Hume on Causes

The great British empiricist philosopher David Hume (1711-1776) wrote that “There are no ideas which occur in metaphysics more obscure and uncertain than those of ‘power’, ‘force’, ‘energy’, or ‘necessary connection'” (An Inquiry Concerning Human Understanding, Library of Liberal Arts ed., p. 73).

Hume is most famous for his critique of naive or dogmatic assumptions about causality. “[T]here is not, in any particular instance of cause and effect, anything which can suggest the idea of power and necessary connection” (p. 75). To me, it seems to be the idea of an underlying power or force responsible for causality that he is mainly questioning. He has no doubt that we continually experience instances of cause and effect.

“[There is] no such thing as chance in the world” (p. 69). “[T]he conjunction between motives and voluntary actions is as regular and uniform as that between the cause and effect in any part of nature” (p. 98). Clearly, then, he did believe in the reality of cause and effect, but only wanted to reject naive claims about our knowledge of the world that purport to link experienced instances of cause and effect to explanations in terms of the operation of underlying powers. What we actually experience in these cases is just lawful regularity.

“It is certain that the easy and obvious philosophy will always, with the generality of mankind, have the preference above the accurate and abstruse…. The fame of Cicero flourishes at present, but that of Aristotle is utterly decayed” (pp. 16-17). But on the other hand, “All polite letters are nothing but pictures of human life in various attitudes and situations…. An artist must be better qualified to succeed in this undertaking who, besides a delicate taste and a quick apprehension, possesses an accurate knowledge of the internal fabric, the operations of the understanding, the workings of the passions…. However painful soever this inward search or inquiry may appear, it becomes in some manner requisite to those who would describe with success the obvious and outward appearances of life and manners…. Accuracy is, in every case, advantageous to beauty, and just reasoning to delicate sentiment. In vain would we exalt the one by depreciating the other” (p. 19). Clearly, then, Hume’s polemic against scholastic modes of reasoning does not at all mean he simply rejects the values of “accurate and abstruse” philosophy.

Neoplatonizing tendencies in the Aristotelian commentary tradition led to the common Latin scholastic view of causes as metaphysical powers operating behind the scenes that Hume is mainly concerned to criticize. Aristotle himself identified causes more broadly and much less speculatively with every kind of “reasons why” things are as they are and behave as they do. He did so without making extravagant claims to certain knowledge. Whereas scholastic philosophers characteristically debated the pros and cons of accepting various abstract propositions, Aristotle himself was fundamentally concerned with the use of reason to help interpret concrete human experience (see Aristotelian Causes).

Hume is a great philosopher, and so far I have focused on a positive appropriation of his work, having some points in common with themes I have been pursuing about causality and the notion of power. Robert Brandom’s innovative reading of Kant’s response to Hume points out that there are distinct limits to Hume’s approach.

“Kant read Hume’s practical and theoretical philosophies as raising variants of a single question. On the side of practical reasoning, Hume asks what our warrant is for moving from descriptions of how things are to prescriptions of how they ought to be. How can we rationally justify the move from ‘is’ to ‘ought’? On the side of theoretical reasoning, Hume asks what our warrant is for moving from descriptions of what in fact happens to characterizations of what must happen and what could not happen…. Hume’s predicament is that he finds that even his best understanding of facts doesn’t yield an understanding of either of the two sorts of rules governing and relating those facts, underwriting assessments of which of the things that actually happen (all he thought we can directly experience) ought to happen (are normatively necessary) or must happen (are naturally necessary).”

“Kant’s response to the proposed predicament is that we cannot be in the situation that Hume envisages: understanding matter-of-factual empirical claims perfectly well, but having no idea what is meant by modal or normative ones” (Brandom, Reason in Philosophy, p. 54).

Brandom continues, “To judge, claim, or believe that the cat is on the mat, one must have at least a minimal practical ability to sort material inferences in which that content is involved (as premise or conclusion) into good ones and bad ones, and to discriminate what is from what is not materially incompatible with it. Part of doing that is associating with those inferences ranges of counterfactual robustness…. So, for example, one must have such dispositions as to treat the cat’s being on the mat as compatible with a nearby tree being somewhat nearer, or the temperature a few degrees higher, but not with the sun being as close as the tree or the temperature being thousands of degrees higher. One must know such things as that the cat might chase a mouse or flee from a dog, but that the mat can do neither, and that the mat would remain essentially as it is if one jumped up and down on it or beat it with a stick, while the cat would not. It is not that there is any one of the counterfactual inferences I have mentioned that is necessary for understanding what it is for the cat to be on the mat. But if one makes no distinctions of this sort — treats the possibility of the cat’s jumping off the mat or yawning as on a par with is sprouting wings and starting to fly, or suddenly becoming microscopically small; does not at all distinguish between what can and cannot happen to the cat and what can and cannot happen to the mat — then one does not count as understanding the claim well enough to endorse it” (pp. 54-55).

Brandom concludes, “If that is right, then in being able to employ concepts such as cat and mat in ordinary empirical descriptive claims one already knows how to do everything one needs to know how to do in order to deploy concepts such as possible and necessary — albeit fallibly and imperfectly” (p. 55).

I am actually a little more sympathetic to Hume, in that I don’t read him as categorically rejecting the validity of concepts of necessity, only any possibility of certain knowledge of how they apply to the real world. I personally like the position of Leibnitz that necessity is real but always hypothetical, never categorical. But Brandom is right that Hume does not go on to emphasize how essential our fallible understanding of necessity is to our understanding of ordinary experience.

Kinds of Reason

As Aristotle might remind us, “reason” is said in many ways. All forms of reason are potentially valuable, but there is a very important distinction between what I’ve been calling the ethical reason that is intimately involved with who we are, and other forms that are more like tools we can use. Also, ethical reason relies on concrete judgments of things, rather than formal manipulations.

In some ways — in terms of the role I see it playing — ethical reason is more like what some people have called “will”. I prefer to avoid the term “will” because it is too often associated with an arbitrary power of decision. I do very much think of ethical reason as the thing in us that ultimately decides things large and small, but the kind of decision involved is always at least implicitly ethical (concerning what we “should” do), and therefore by no means arbitrary.

Common complaints against “reason” concern what I would call what I would call a usurpation of the place of ethical reason by the tool-like kinds of reason, or claims made on their behalf. Contrary to the claims of a certain ill-conceived modernity, tool-like reason can aid us in utilitarian calculations that may help inform decisions, but cannot by itself provide an adequate basis for decision, which is always ultimately ethical.

Whereas tool-like reason aims at precision, ethical reason is maximally inclusive in what it takes takes into account. This inclusiveness is its strong point, but at the same time makes it especially fallible. Due to the fact that we are situated beings in the world, there is no such thing as an infallible decisionmaking process we could use. Aristotle already pointed out that ethical reason is less precise than other forms. Tool-like reason achieves its precision by excluding considerations that ethical reason cannot ignore.

Because of this, concrete realizations of ethical reason can be better or worse. In general, human beings are called rational animals not because we are perfectly rational, but because we have the capability for reason. Especially in the case of ethical reason, that capability is always a matter of degrees. We all use it all the time, and do better or worse. We can also learn or be inspired to do better than we did before.

Fallible Humanity

Fallible Man (French ed. 1960) was the next installment after Freedom and Nature in Paul Ricoeur’s project for a philosophy of will. This account of our fallibility was to set the stage for the following installment dealing with the problem of evil, which I will address separately.

The main body of this shorter book develops a nice interweaving of Aristotelian and Kantian anthropology, with special emphasis on the role of feeling. We are “intermediate” beings, mediating beings, and as such there is an inherent “disproportion” in our relations to self. “[T]his ‘disproportion’ of self to self would be the ratio of fallibility” (p. 4; emphasis in original).

Ricoeur says we can retain neither the Cartesian distinction between a finite understanding and an infinite will, nor any other convenient mapping of “finite” and “infinite” to separate faculties. Character makes us finite, but our participation in language involves us in what he calls a kind of infinity. An ethical Self finally uniting these aspects of our being should be considered as an end and ongoing project rather than an actuality.

Philosophical anthropology has to proceed as a “second order elucidation of a nebula of meaning which at first has a pre-philosophical character” (p. 8). As a consequence, method has to be dissociated from the idea of a starting point. “Philosophy does not start anything independently” (ibid).

He adopts the language of Blaise Pascal (1623-62) on the “pathos” of human “misery”. I don’t like such pessimistic rhetoric, but fortunately Ricoeur says the whole pre-comprehension of this “misery” is contained in the more moderate Platonic myths of the soul.

“The [Platonic] soul… is the very movement from the sensible toward the intelligible… its misery is shown in that it is at first perplexed and searches…. The soul holds opinions and makes mistakes; it is not vision… but an aim. It is not contact and possession… but tendency and tension” (pp. 12-13). “Instead of a well-balanced structure, it is a non-determined movement, a system of tensions which emerges” (p. 14). Plato speaks of an ambiguous power of the soul that is affected by both reason and desire, and results from a kind of mixture. For Plato, the account must take a mythical form, because such matters cannot be explained in terms of permanent realities.

My body is a “zero origin” that ties every perception to a point of view (p. 33). Invoking a common Husserlian theme, Ricoeur notes that perception involves inference about the back sides of things that we cannot see, and so on.

More broadly, our character may be viewed as the summation of many limiting “perspectives”, at the same time that our engagement in acts of conceptual determination implicitly involves a degree of “transgression” of those pre-given limitations (p. 38).

Ricoeur argues that our very ability to recognize something as a perspective implicitly involves a “transgression” or escape from limitation by the perspective. “Therefore, I am not merely a situated onlooker, but a being who intends and expresses as an intentional transgression of the situation” (p. 41). “[T]he project of a phenomenology of perception, wherein the moment of saying is postponed and the reciprocity of saying and seeing is destroyed, is ultimately untenable” (p. 42). “I say more than I see” (p. 44). Referring to Hegel, he adds “We are always already in the dimension of truth” (p. 46). “The fact that the self is at variance with itself is the indefeasible worm in the fruit of the immediate” (ibid; emphasis in original). “Here again we must not move too quickly to the side of the subject, act or noesis, but proceed reflectively beginning with the object, content and noema” (p. 49). Referring to Aristotle, he talks about the “power of the verb” to express affirmation and judgment. “I myself become a synthesis of speech and perspective in this projection of objectivity” (p. 61). “[I]f point of view is a characteristic of openness, namely its narrowness, openness indicates that my point of view is transgressed” (p. 62).

Ricoeur says these considerations suggest something like the Kantian transcendental synthesis of imagination, in its mediating role between the passivity of sensible intuition and the activity of thought. He also relates them to the experience of time.

“Plato… advised against rushing headlong into the abyss of the infinite or into that of the One but recommended learning to linger in between…. What Plato said of the One we can apply to the totality. Nothing gives rise to deception more than the idea of totality. All too quickly it has been said: It is here, it is there, it is Mind, it is Nature, it is History. Violence is the next step” (pp. 73-74). Instead, the idea of totality should be taken as a task, a Kantian imperative.

Our practical finitude is summed up in the notion of character. Ricoeur provocatively suggests that our practical “infinitude” with respect to the constitution of meaning is summed up in Aristotle’s notion of happiness. What extends the mediation of the Kantian transcendental synthesis of imagination into the practical domain, he says, is the constitution of the person through Kantian respect.

“Character is the finite openness of my existence taken as a whole” (p. 89). There is no science of character. Ricoeur says “My humanity is my essential community with all that is human outside myself…. [M]y character is that humanity seen from somewhere” (p. 93).

Desire too fundamentally involves a kind of openness. We are not enclosed within our desire. But there is also an affective opacity or closing involved in attachment.

Bergson is quoted saying each feeling of sufficient depth represents the whole soul.

“The person is the Self which was lacking to the ‘I’ of the Kantian ‘I think’…. The Self is aimed at rather than experienced…. There is no experience of the person in itself and for itself” (p. 106). The person is the synthesis of the “antithetical notions” of character and happiness. “[T]he person is primarily the ideal of the person” (p. 110).

According to Ricoeur, feeling already overcomes the duality of subject and object. It simultaneously tells us something about both. Feeling is essentially concerned with values, and simultaneously with what is. “If one does not take into consideration the primordial disproportion of vital desire and intellectual love (or of spiritual joy), one entirely misses the specific nature of human affectivity” (p. 140).

Not pleasure itself but a blind preference for pleasure is evil. “[H]appiness, restored by the reflection on the ‘excellences’ of the ‘good’ man, is ultimately the highest form of the pleasant” (p. 148). Thomistic and Cartesian analysis of the passions fails to see the “innocence of ‘difference’ under the cloak of vain and deadly ‘preference'” (p. 163). “[E]ncountering of another person is what breaks the finite, cyclic pattern of the sensible appetite” (p. 168).

Kantian anthropology should learn from Aristotle’s treatment of pleasure, and seek to discover behind passions an innocent quest that is “no longer mad and in bondage but constitutive of human praxis and the human Self” (p. 170). Later he quotes Hegel saying all great accomplishments involve passion, while a morality that simply condemns passion is deadly and too often hypocritical.

“The quest for reciprocity, which no will to live can account for, is the true passage from consciousness to self-consciousness” (p. 184). “I esteem myself as a thou for another” (p. 188). “[T]his belief, this credence, this trust, constitutes the very feeling of my worth” (p. 189). “[I]ts character of belief makes its corruptions possible: what is believed is presumed; and the presumption of the preesumed can turn into the presumption of the presumptuous” (p. 190). According to Ricoeur, the unstable, ambiguous “middle part” of the soul in Plato’s myth mixes the vital and the spiritual. Feeling prospectively binds things together, in the process creating the disproportion of self to self. This is the fragility of the human being, with immense potential for both good and evil.
