Reflection and Apperception

According to Robert Pippin, the most important feature of Kant’s theory of thinking, account-giving, and judging is that “judging is apperceptive” (Hegel’s Realm of Shadows, p. 103). “Apperception” is a term coined by Leibniz. The “ap-” prefix etymologically suggests a redoubling of perception, or a “perception of perception”. Leibniz broadens its meaning to cover all forms of self-awareness. Aristotle’s surviving texts include only a few lines about the “common sense”, which both synthesizes inputs from different senses into perceptions of objects, and is the root of self-awareness. Kant’s first and third Critiques greatly expand on this.

Pippin quotes Kant’s Critique of Pure Reason, “I find that a judgment is nothing other than the way to bring given cognitions to the objective unity of apperception” (p. 102), commenting, “This is a new theory of judgment and accordingly grounds a new logic” (ibid). That judging is apperceptive is for Hegel a logical truth.

Therefore, for Hegel “it is quite misleading for Kant to formulate the point by saying that the ‘I think’ must ‘accompany’ (begleiten) all my representations (B132). Representing objects is not representing objects, a claiming to be so, unless apperceptive (which is in effect what the B132 passage claims). And that has to mean, in a very peculiar sense that is important to Hegel and that will take some time to unpack, that such judgings are necessarily and inherently reflexive, and so at the very least are self-referential, even if such a reflected content is not substantive, does not refer to a subject’s focusing on her judging activity as if it were a second consciousness.”

“Virtually everything in [Hegel’s] Logic of significance descends in one way or another from the proper understanding of this claim” (p. 103).

He quotes Hegel, “The concept, when it has progressed to a concrete existence which is itself free, is none other than the ‘I’ or pure self-consciousness” (p. 104).

I like to turn this last point around, and say that self-consciousness, the pure ‘I’, for Hegel is none other than the concept — not a static self-image, but a pure reference to the active taking of things to be thus-and-such. My individual essence as a “rational” animal is constituted by all that I care about and hold to be true, as confirmed in my actions and follow-through, not by what I happen to believe about myself.

What Pippin calls the “very peculiar” sense in which apperceptive judging inherently involves reflection and self-reference seems completely normal to me. My self-consciousness straightforwardly consists of what I actually care about and hold to be true, not some abstract “consciousness of consciousness”, in which ordinary consciousness would be its own object. It is not mere organic consciousness or “awareness”, but self-consciousness — Kantian discursive “taking as” — that is inherently reflexive.

This is a relational reflexivity that does not presuppose a substantial “self”, only a kind of “adverbial” self-reference. Takings have reasons, which in turn have other reasons. When all goes well, the reasons mutually support one another, and there is no infinite regress. This results in what Kant calls a unity of apperception, which is a truer, deeper self than any self-image we may have, and indeed not an image at all — and not something presupposed or achieved once and for all, but something we must constantly aim for anew, even when we did just achieve it.

We are the sum of our takings. Meanwhile, what we take to be the case — and what we take to be important or good — is not necessarily what we say it is, but what our actions and follow-through imply.

Wisdom and Judgment

For Aristotle, the ultimate aim of a talking animal as such is wisdom, which cannot be separated from ethical sensitivity and concern for others. This wisdom might be characterized as an excellence in reflective judgment or interpretation.

There has, however, come to be a traditional view of what is called judgment — especially common in early modern logic — that reduces it to the grammatical form of predication (“A is B”), and its truth to a matter of simple correspondence to fact, which is presumed to be independently knowable. Predication on this view aims to be a kind of authoritative saying of how things are, grounded in putatively immediate truth that is not supposed to depend on any kind of normative inquiry or process of interpretation in order to be known. Things just factually are certain ways, and judgments are conclusions produced immediately that are supposed to correspond to the facts. Judgments are either right, and thereby count as objective; or wrong, and to be dismissed as merely subjective. But in neither case do they involve any depth of engagement or extensive activity. They are “shallow”.

This dogmatic way of thinking, criticized by Kant and Hegel, is utterly alien to the kind of spirit of rational inquiry promoted by Plato and Aristotle, who thought that assertions should be grounded in reasons shareable and discussible with other humans, and not on vain claims of immediate insight. But both this reductive use of “judgment” for the mere immediate production of a representation, and the reduction of truth to a correspondence to presumed fact, have often been wrongly characterized as Aristotelian, when they are really of much later origin.

I would suggest that the very idea of better or worse judgment, or of judgment as something of which there could be an excellence, is incompatible with the shallow black-and-white view of judgment as simply right or wrong. Judgment as activity is anything but an immediate production. It is an extensive and intensive activity of interpretation and reflection.

The contemporary American philosopher Robert Brandom writes, “Here is perhaps Kant’s deepest and most original idea…. What distinguishes judging and intentional doing from the activities of non-sapient creatures is not that they involve some special sort of mental processes, but that they are things knowers and agents are in a distinctive way responsible for…. Judgments and actions make knowers and agents liable to characteristic kinds of normative assessment. Kant’s most basic idea is that minded creatures are to be distinguished from unminded ones not by a matter-of-fact ontological distinction (the presence of mind-stuff), but by a normative deontological one. This is his normative characterization of the mental” (Reason in Philosophy, pp. 32-33; see Kantian Intentionality).

Over the course of many posts, we have seen not only that what Aristotle calls nous and gets translated as “intellect” is an activity and not a stuff, but also that it is intrinsically concerned to seek the better in each instance. The highest good for Aristotle is not a pre-given content, but the result of a truly consistent aiming at the better in life, where what is better is intelligible, and once again not pre-given, but expressible in terms of reasons that any human can share in evaluating.

A important notion of responsibility is also implicit in Aristotle, as when he points out that the freedom of ethical beings is not an arbitrary license, but is commensurate with the taking of responsibility. For Aristotle, unfree beings have no responsibility insofar as they are unfree. It is free beings capable of real deliberation and choice that have responsibility.

On the other hand, at a top level Aristotle prefers to stress the affirmative values of friendship, love, and reciprocity over the constraints of responsibility. For Aristotle, an ethically serious person guided by affirmative aims will turn out to be responsible in her actions. Kant was more distrustful of our affirmative aims, as possibly biased by our individual impulse, and therefore tended to emphasize duty and responsibility as more reliable motivators for ethical action. Aristotle has the more optimistic view that there can be such a thing as desire that is consistent with reason about what is better. (See also Intellectual Virtue, Love; The Goal of Human Life).

Primordial Choice?

Plotinus speaks of a primordial choice implicitly made by every human: to turn either toward the separated soul, or away from it. The idea is that such a choice comes first, and is not conditioned by anything. This is completely unlike Aristotle’s treatment of choice.

Aristotle discusses choice in the context of concrete ethical doings. A choice is the outcome of a deliberation, not something undertaken in a vacuum. Our freedom consists in many such choices, based on reasons. Our unfreedom consists in part in constraint by the cumulative consequences of all our previous choices.

(I call this particular kind of unfreedom superficial because because it is “unfree” mainly in the shallow sense that it is not completely unconditioned. A conditioning grounded in reasons that we assent to is very unlike a conditioning by relations of force. In a deeper sense, a grounding in reasons doesn’t at all make us less free; indeed, many philosophers have made a grounding in reasons the very criterion of freedom. Of course, our choices may also have unintended consequences, and we have to live with these as well. That is a less superficial unfreedom. And we may be swayed by passion or imagination, which is another kind. Or we may be constrained by relations of force.)

In modern times, various writers have abstracted the notion of unconditioned choice even further, so that in principle anything could be a matter of purely arbitrary decision. Completely unconditioned choice can only be arbitrary. Here lie the seeds of tyranny. (See also Desire of the Master.)

Negation and Negativity

“Hegel is willing to say some extraordinary things about the concept he sometimes calls ‘negation’, sometimes ‘negativity’. What he has been taken to mean has been the source of most of the criticism of Hegel: that he confused logical negation with actual opposition, as in the oppositions of forces or magnitudes in general in the world; that he thought everything in the world contradicted itself, and so believed that pairs of contradictory judgments could both be affirmed; or simply that what he said about negation and contradiction cannot be coherently understood. And any commentator must face the fact that he invoked the notion of negation in many different contexts in many different ways. So the first task is to have in view that variety of contexts before we can understand what they all might have in common (if anything)” (Pippin, Hegel’s Realm of Shadows, p. 139).

Some time ago I touched on the most elementary parts of this thorny issue in Contradiction vs Polarity. My basic sense at this point is that Hegel does indeed have very worthwhile things to say on this very distinctive theme of his, but that the standard connotations of his core vocabulary for talking about it — negation, negativity, contradiction — are so impoverished relative to what he really means in his extensive and varied metaphorical uses of it that the vocabulary does not communicate well.

Pippin identifies five somewhat overlapping contexts that ought to be taken into account in a serious interpretation of Hegelian negation: the nature of thinking; the talk about freedom; the nature of intelligibility; the notion of speculative truth; and the talk about contradiction.

In the context of the nature of thinking, he says “In the simplest sense, we are talking about the logical structure of apperceptive intentional knowledge, as well as the ontological status of agency. What it means to claim that the intelligibility of any content of empirical knowledge is not… wholly ‘positive’… is best understood by contrast. If it were not so and were wholly positive, subjectivity would be something like a mere complex registering and responding device (of the same ontological status as a thermometer) ” (p. 141).

“As we have seen, one is not simply wholly absorbed in the presence of the world to one, not wholly and merely reactive to the stimulation of sensibility, and that ‘not’ is the beginning (but certainly not the end) of all the logical issues of negation that emerge in Hegel’s philosophy, at both the phenomenological and the logical level. In making such a judgment I ‘negate’ the mere immediacy or givenness of perceptual content, negate it as immediate and putatively given, and take up, am always taking up, a position of sorts about what is there, what is the case” (p. 142).

The suggestion is that all “taking” of things to be thus-and-such for Hegel implicitly involves a negation of immediacy.

“What thinking is is such a ‘negation’ of one’s immediate ‘positive’ state. (One can say: this negation of mere immediacy is ‘taking a stand’, rather than being put into a state.) Any thinking could be a seeming-to-be-the-case, not what is the case, and that possibility is constitutive of the act’s being a judging in the first place…. The constitutive feature attended to in a Hegelian philosophical logic is the fact that judgments are potentially responsive to reasons and revisions just qua judgments” (ibid).

Pippin thus cites responsiveness to reasons as another non-obvious instance of negation for Hegel.

“And in being an agent, I am not simply causally responsive to inclinations and desires; there is no ‘fullness of positive being’ here either. I interrupt or negate positive being (what I feel inclined to do, experience as wanting to do) by deliberating and resolving what to do” (p. 143).

Deliberation is another non-obvious instance.

“As noted before, the closest first and general approximation of what he means is Aristotelian: subjectivity (thinking and acting according to norms) is the distinct being-at-work… of the biological life form that is the human, reason-responsive substance; this in the same sense in which Aristotle says, if the eye were body, seeing would be its form, its distinctive being-at work” (ibid).

Subjectivity in general is another.

“Instead of thinking of the fundamental act of understanding as a synthesis of independent, originally unrelated elements, either by subsuming an individual under a concept, or by including one concept under another, we should understand ourselves, both in experience and in logical reflection, beginning with ‘wholes’, never with experiential or logical subsentential simples [individual words] or atoms” (pp. 143-144).

Hegel presents this last point as a sort of inversion of Kant, and it does speak to some of Kant’s language. But I would argue that the true starting point of Kantian synthesis is not experiential or logical atoms, but rather the sensible manifold in intuition, which is only potentially differentiable. This brings Kant closer to Hegel. True, the manifold has such a loose unity that arguably it might have trouble qualifying as a “whole”, but even less does it consist in already predifferentiated “atoms”. In Kant I think we have no basis for identifying putative atoms in experience until “after” the figurative synthesis of imagination has done its work. (It is the preconscious, in a non-Kantian sense “spontaneous” figurative synthesis that for Kant creates an inevitable gap between being and thinking, and that for Hegel gives us the fixed representations relied upon by common sense.)

In the context of freedom, Pippin says that “In the same way that judging, insofar as it is genuine, holds open the possibility of its negation or disconfirmation, just by being judging, not by virtue of any second, reflective act…, a deliberation about action, if it is to be a deliberation, is open to the force of reasons the agent has already accepted by deliberating at all, a possibility criterial for his acting at all…. [Hegel] is insisting on the logical or categorical requirements of the normative, and in that sense (the sense in which freedom is normatively constrained judgment and rational action), the negative (here only the possibility of not doing what I am powerfully inclined to do) is ‘that by which a person is free’. (And he does not mean any uncaused causality, but that which counts to the subject as a reason” (p. 147).

Normativity in general thus counts as depending on a kind of negation.

“In terms of the structure of the Logic, what Hegel will want to argue is that we cannot adequately explain freedom if we consider just a determinate property that some beings happen to have…, and we cannot explain it either as a kind of essential ideal, manifest in but never adequately expressed in its appearances, in concrete individual actions…. We need the logic of the Concept, in which concepts are said to ‘give themselves their own content’ and be ‘self-determining’ in a way indebted to [the] Kantian claim on self-legislation…. Any philosophical determination of actuality must be understood as ‘self-legislating’ in the broad sense [that] reason relies only on itself in determining such a normative structure. These are not empirical questions. There is no flash of ‘essence intuition’ (Wesenschau) giving access to a world of abstract immaterial objects, essences” (p. 148).

Self-legislation too involves some subtle kind of negation.

In the context of the nature of intelligibility, Pippin says “Every determination of every sort of content in the Logic is a negation of some insufficient determinacy that must be able to be conceived positively” (p. 153). This is another way of characterizing the basis of the notorious “movement” in Hegel’s logic.

The determination of content for sure involves negation.

In the context of speculative truth, he mentions that “[E]valuative judgments, like ‘this action is good’, or our familiar ‘this is a bad house’, will be paradigmatic examples of judgment in the logic of the Concept. They do not qualitatively specify a thing by distinguishing it from other things; they do not identify the appearances that show the ‘essence’ of the thing; they understand the content ‘in terms of its concept'” (p. 154).

Evaluation of anything against its concept is another subtle variety.

In the context of the notorious “contradiction”, Pippin says “So in a general sense, one has to say that a thing… ‘includes’ its contrary, or more precisely its relation to its contrary, in order to be, and be known to be, what it is. Neither of these ‘moments’ of negation involves contradiction in the Aristotelian sense because ‘is’ and ‘is not’, while said of the same thing and at the same time, are not meant in the same sense. But Hegel wants for various reasons to call such an analyzed state a ‘contradiction’, and there is some ground in the use of the term for saying that…. In the simplest sense, personifying the process, what someone intends to say, means to say, can be ‘contradicted’ by what is actually said, what he finds he has to or can say” (p. 156).

Evaluation of any outcome against intent is another.

Pippin notes that Hegel says retrospectively at the end of the Logic that the abstract treatment typical of the logic of being and the logic of essence is due to “mere opinion” or lack of awareness of what it is actually treating. “It cannot say what it means to say” (p. 157). This is yet another way of characterizing the Logic‘s “movement”.

Logical “movement” is another.

“Hegel’s speculative notion of contradiction is not predicate or sentence negation…. [H]e means to focus attention on concept negation…. Now concepts, understood as rules, have content by being understood to have the content that they have. To understand a rule is to know how to use it, and in using it, to know one is following it…. So understanding… is not… ‘grasping a content’ but understanding what the rule instructs us to think. That is, the concept is always already a moment of discursive activity, a thinking through of its implications” (pp. 158-159).

“[T]he considerations discussed so far should not be understood to be matters of formal clarity…. As Hegel insisted, we are not studying how we think about (or talk about) matters (or even how we ‘must’ think). The question is a question about ‘any possible intelligibility’, and so about being in its intelligibility, … not ‘our ways’ of rendering intelligible” (p. 160).

All the above varieties of “negation” involve normativity in one way or another. Here Pippin again emphasizes the universality of criteria of intelligibility that Hegel counterposes to the Kantian gap between thinking and being.

“The forms of intelligibility are the forms of what could be true, although they do not settle the question of what, in particular, is true” (p. 175).

“[O]ur first orientation in trying to understand Hegelian negation should be not the logical operation of predicate or sentence negation, but real opposition…. [Michael] Wolff also thinks that the controversy in the eighteenth century about positive and negative magnitudes, especially as it surfaced in Kant, as well as the emerging clarity about negative numbers, played a far larger role in the development of Hegel’s thinking about negation and contradiction than did a reflection on the logic of the formal operator” (pp. 177-178).

Real opposition is an instance of contrariety, which is actually much more relevant to Hegel than formal logical contradiction.

“Hegel’s category of becoming, so important at the beginning of the logic of being, owes much to Hegel’s defense of Newton and the latter’s doctrine of the becoming equal of magnitudes” (pp. 178-179).

“Critics like Crusius were aghast at the idea of forces having positive and negative values. But Kant understood that such ‘values’ (and here again an important precedent for Hegel) had those values in relation to each other, not absolutely, that they were relative values, arbitrarily reversible even” (pp. 179-180).

Negative magnitudes are another instance of contrariety.

“This is not the sense of contradiction throughout the Logic, but it gives us enough background… to appreciate that Hegel is neither a lunatic for saying that ‘everything is contradictory’, nor a mystical Heraclitean” (p. 180).

Pippin devotes nearly half of this chapter to critical remarks about Brandom’s interpretation of Hegelian negation as material incompatibility, which involves a more nuanced form of contrariety. He says Brandom’s reading very well captures the meaning of negation in Hegel’s logic of being, but is inadequate for what Hegel goes on to do in the logic of essence and the logic of the concept. For example, material incompatibility alone is insufficient to explain things like the “self-legislation” of the concept or the idea of the good, but Hegel at least claims that these have something to do with the concept of negation.

Brandom’s interpretation of Hegelian negation seemed to me incomparably clearer than Hegel himself, so until now I have adopted it enthusiastically as a charitable rendering of what Hegel ought to have said to better express his meaning. This is the first of many counter-arguments to Brandom I have seen that really seems to me to at least raise a serious question, but for now I will forego another lengthy tangent.

Next in this series: Deeper Truth

Facts and Incomplete Information

A modern notion of hard-nosed common sense is to appeal exclusively to positive facts. This is also a major basis of simplistic notions of empirical science. Serious scientific methodologies are more indirect, and quite a bit more involved.

From a broadly Kantian point of view that I think Plato and Aristotle would also endorse, all putative facts are really just assertions of facts, made by people. The validity of the corresponding assertions depends on the soundness of the reasons that lead us to believe them. Thus, regardless of whether our concern is ethical or scientific, it is always the quality of reasons that matters in assessing the validity of assertions.

The notion of a fair and objective weighing of evidence for or against an assertion presupposes that we symmetrically consider the pro and con, as Plato emphasized in his discussions of “dialectic”. But the simplistic bias for positive facts results in an inherently asymmetrical treatment any time we have to deal with incomplete information, because what putative facts we currently have in our possession is in part a matter of sheer chance.

In a fact-biased approach, if there happen to be insufficient facts in our possession to adequately support a hypothesis, the hypothesis is likely to be be dismissed out of hand as “speculation”, regardless of how inherently plausible it might otherwise be. We end up assuming something is not true merely because we cannot empirically prove it is true. This is independent of any other prejudice that may also enter into situations involving human judgment.

Once again, I want to recommend a prudent suspension or qualification of belief in cases of incomplete information, rather than active disbelief. (See also Debate on Prehistory.)

Cause

Aristotle flourished before the great flowering of Greek mathematics that gave us Euclid, Ptolemy, Apollonius, and Aristarchus. In his day, mathematics amounted to just arithmetic and simple geometry. In spite of the famous Pythagorean theorem that the square constructed from the hypotenuse of a right triangle is equal in area to the sum of the squares constructed from the other two sides, the historic reality of the Pythagorean movement had more to do with number mysticism, other superstitions, and curious injunctions like “don’t eat beans” than it did with real mathematics.

I think Aristotle was entirely right to conclude that arithmetic and simple geometry were of little use for explaining change in the natural world. I’ve characterized his physics as grounded in a kind of semantic inquiry that Aristotle pioneered. We are not used to thinking about science this way, as fundamentally involved with a very human inquiry about the meaning of experience in life, rather than predictive calculation. For Aristotle, the gap between natural science and thoughtful reflection about ordinary experience was much smaller than it is for us.

Aristotle invented the notion of cause as a semantic tool for expressing the reasons why changes occur. Aristotle’s notion is far more abstract than the metaphor of impulse or something pushing on something else that guided early modern mechanism. Even though the notion of cause was originally developed in a text included in Aristotle’s Physics, the “semantic” grounding of Aristotelian physics places it closer to logic than to modern physical inquiries.

I think the discussion of the kinds of causes could equally well have been grouped among his “logical” works. In fact, the form in which we have Aristotle’s works today is the result of the efforts of multiple ancient editors, who sometimes stitched together separate manuscripts, so there is room for a legitimate question whether the discussion of causes was originally a separate treatise. We tend to assume that there must be something inherently “physical” about the discussion of causes, but this is ultimately due to a circular argument from the fact that the more detailed version of it came down to us as part of the Physics (there is another, briefer one that came down to us as part of the Metaphysics).

Since Hume and especially since the later 19th century, many authors have debated about the role of causes in science. Bertrand Russell argued in the early 20th century that modern science does not in fact depend on what I have called the modern notion of cause.

More recently, Robert Brandom has argued that the purpose of logic is “to make explicit the inferential relations that articulate the semantic contents of the concepts expressed by the use of ordinary, nonlogical vocabulary”. I see Aristotelian causes in this light.

I want to recommend a return to a notion of causes in general as explanatory reasons rather than things that exert force. This can include all the mathematics used in modern science, as well as a broader range of reasons relevant to life. (See also Aristotelian Causes; Mechanical Metaphors; Causes: Real, Heuristic?; Effective vs “Driving”; Secondary Causes.)

Everyday Belief

In ordinary life we are guided by well-founded beliefs about many things of which, strictly speaking, we do not have knowledge. Our beliefs are still well-founded in the sense that if asked, we can give reasons for them, and plausibly respond to questions about those reasons. We ought to continue to hold those beliefs, unless and until we are confronted with better reasons for a different conclusion.

Brandom would remind us that we have an implicit ethical obligation to keep our beliefs in good repair. We have a responsibility for the consequences of applying our beliefs. We have a responsibility not to hypocritically pretend to hold incompatible beliefs. In general, we have a responsibility to take our explicit and implicit commitments seriously. This entails a willingness to participate in dialogue, to explain our reasons and answer questions about them.

Opinion, Belief, Knowledge?

There is an empiricist commonplace that identifies “knowledge” with “justified true belief”. This makes knowledge an especially good kind of belief. I regard that as a flat-out category mistake.

I want to suggest that knowledge is not a kind of belief or opinion at all. As usual, I don’t claim to “know” what I “suggest” with some force as interesting or worthy of consideration, so in particular I do not claim to know that knowledge is not belief or opinion. (I am also not trying to say exactly what knowledge is, only to delimit it somewhat.)

What I am doing is recommending a different use of the word “knowledge”, that at minimum distinguishes it from belief or opinion. This is based on the belief or opinion that the belief or opinion that “knowledge is not belief or opinion” is a well-founded belief or opinion.

I read Plato as very sharply distinguishing “knowledge” properly so-called (epistémé) from any kind of doxa (opinion or belief). This would rule out the identification of knowledge with justified true belief.

It is not uncommon, however, to see claims that Plato himself identified knowledge with justified true belief. I will offer a different interpretation of the main relevant passage here. I apologize for using the old Jowett translation, which is easily accessible online.

“Then when the jurors are rightly persuaded of something one could not actually know except by being present — when they judge it, that is, on hearsay, and yet with a true opinion, they judge it without knowledge; even though, if their decision is sound, their persuasion is correct” (Plato, Theaetetus 201).

Ignoring the particular criterion of knowledge mentioned in the example, the essential is that on reflection, we should all be able to agree that there are cases in which we would say that someone has a true opinion without knowledge. So far, this is agnostic to whether or not knowledge is justified true opinion. It just establishes that true opinion in itself is not knowledge.

“When therefore anyone conceives a true opinion of anything without a reasoned statement, his mind is free from error about it, but does not know it; for the man who cannot give and accept a reasoned statement about anything, has not knowledge of it: but when he adds to his true opinion a reasoned statement, he has in addition all that is required to constitute knowledge” (202).

Here it is very important to distinguish between statements about knowledge and statements about someone who has it. What is argued in the above quotation is that the person who has a true opinion and a reasoned statement has what she needs for knowledge.

I would agree that a person who has knowledge can reasonably be said also to believe what she knows. But it does not follow from this that knowledge itself is any kind of belief, or in particular that knowledge is just true belief accompanied by a reasoned statement. Nothing in the argument excludes the possibility that knowledge itself — as distinct from the person who has both knowledge and belief — is tied only to the reasoned statement, and is in itself independent of the person’s belief.

I think this is already sufficient to disprove the claim that this section of the Theaetetus expresses the view that knowledge is reducible to justified true belief.

If knowledge were tied only to the reasoned statement, it would still be true that the person who also had a true belief would have what she needed for knowledge. Again, I don’t mean to say that “reasoned statement” is sufficient by itself to define knowledge, even though I think it gives an important hint. It is worth noting, however, that Plato’s mention of a reasoned statement is more specific than the simple mention of justification.

Also, “truth” is said in more than one way. The kind of truth that could reasonably be said of a belief or opinion is only a correspondence to facts. The kind of truth of principal interest to Plato was very different from this.

I also think there is a broad category of acquaintance that is extremely important to humans, but is different from knowledge. The kind of experience I find interesting is mainly not ephemeral immediate experience, but the more substantial thing that we mean when we say someone is “experienced”. (See also Imagination, Emotion, Opinion; Consciousness, Personhood; A Criterion for Knowledge?; Everyday Belief; Belief is Different from Faith.)

History of Ethics: Plato

Traditional communities, even the most “primitive” known to modern anthropology, have well-defined, generally accepted ways of distinguishing good and bad actions. Hegel called this “ethical substance”.

What I call “ethics” involves a second level, in which the criteria for good and bad are subject to discussion. Here we are not simply laying down the law, but inquiring into the principles that ought to govern distinctions between good and bad. The oldest documented example of this kind of inquiry in our planetary family of cultures is the writings of Plato. How much of the literary character of Socrates in Plato is attributable to the historic Socrates is debated by scholars, but need not concern us here. It is in Plato that we find an actual record of Socratic inquiry. Other so-called “minor Socratic” schools also claimed to be inspired by Socrates, but left no record of critical give and take comparable to what we find in the dialogues of Plato.

Plato clearly recognized the weakness of argument from authority, and put the reasoned examination of principles before the mere fact of anyone’s say-so. He further pointed out that assertions about God’s will and its applicability to real-world cases need to be evaluated as human assertions, on the same footing as others. In discussions about truth, there are no specially privileged assertions or asserters. He set a strong ideal of sincerely seeking knowledge rather than assuming we have it, and by example promoted the modest attitude that humans should avoid making strong claims that human knowledge cannot validate. Many of his most important ideas are only presented as what I call “suggestions”.

Provocatively, Plato suggested that all beings desire the good, and that the Good is the most ultimate formative principle of all things. This reduces evil to ignorance of the true Good. The tendentious claim here is that evil is a kind of lack or defect, and that no one who aims at what is really evil properly understands what they are doing. This gives fundamental ethical significance to knowledge and the quest for better understanding. Treating evil as due to some lack of understanding also suggests a way of forgiving the evil-doer.

For Plato, wisdom and goodness are correlative. Wisdom especially includes the recognition of what we do not know. It is superior to any law. The most wise are the best qualified to govern, but do not want the job and must be coaxed into doing it.

Plato was unconcerned with questions like who decides who is wise, preferring to focus instead on how such judgments should be made. For the latter, he suggested the same kind of free and open dialogue and examination of reasons as for any other questions about truth.

Leibniz on Justice vs Power

In Meditation on the Common Concept of Justice (ca. 1703), Leibniz made points that deserve to be quoted at length. Editor Patrick Riley notes that “Leibniz’ radical formulation of this question follows Plato’s Euthyphro (9E-10E) almost literally, though Plato was dealing with ‘holiness’ rather than justice” (Leibniz, Political Writings, p. 45).

Leibniz says, “It is agreed that whatever God wills is good and just. But there remains the question whether it is good and just because God wills it or whether God wills it because it is good and just: in other words, whether justice and goodness are arbitrary or whether they belong to the necessary and eternal truths about the nature of things, as do numbers and proportions” (ibid).

For present purposes, what is important is whether justice and goodness depend on an arbitrary will or have criteria of their own, not whether those criteria are necessary and eternal.

To say that justice and goodness depend upon an arbitrary will “would destroy the justice of God. For why praise him because he acts according to justice, if the notion of justice, in his case, adds nothing to that of action? And to say… my will takes the place of reason, is properly the motto of a tyrant” (pp. 45-46; brackets in original).

“This is why certain persons, too devoted to the absolute right of God, who have believed that he could justly condemn innocent people and even that this might actually happen, have done wrong to the attributes that make God lovable, and, having destroyed the love of God, they left only fear [behind]” (p. 46; brackets in original).

“Thus all [Lutheran] theologians and most of those of the Roman Church, and also most of the ancient Church Fathers and the wisest and most esteemed philosophers, have been for the second view, which holds that goodness and justice have their grounds… independent of will and of force.”

“Plato in his dialogues introduces and refutes a certain Thrasymachus, who, wishing to explain what justice is, [says] that is just… which is agreeable or pleasant to the most powerful. If that were true, there would never be a sentence of a sovereign court, nor of a supreme judge, which would be unjust, nor would an evil but powerful man ever be blameworthy. And what is more, the same action could be just or unjust, depending on the judges who decide, which is ridiculous. It is one thing to be just and another to pass for it, and to take the place of justice.”

“A celebrated English philosopher named Hobbes, who is noted for his paradoxes, had wished to uphold almost the same thing as Thrasymachus: for he wants God to have the right to do everything, because he is all-powerful. This is a failure to distinguish between right and fact. For what one can do is one thing, what one should do, another” (pp. 46-47; brackets added).

“[I]f power were the formal reason of justice, all powerful persons would be just, each in proportion to his power; which is contrary to experience.”

“It is thus a question of finding this formal reason, that is to say, the why of this attribute, or this concept which should teach us what justice is” (p. 48). By “formal” Leibniz here means something like “essential”.
