Nietzsche famously criticized received notions of good and evil, and pointed out the inglorious role of “reactive” and resentful thinking about morals. To negatively frame our notions of goodness and virtue in terms of emotional reactions to bad things done by others is not an auspicious beginning for ethics. It results in a bad order of explanation that puts negative judgments of others before positive consideration of what is right.
Nietzsche pointed out that this occurs more often than we might think. A recurring emphasis on negative, blaming attitudes toward other people over affirmative values is unfortunately all too common not only in ordinary life and actually existing religious practice, but across what passes for the political spectrum. We ought to distance ourselves from this, and develop our values in positive rather than negative terms. We should aim to be good by what we do, not by contrasting ourselves with those other people. As an antidote to resentment, Nietzsche recommended we cultivate forgetfulness of wrongs done by others. I would add that we can have strong concern for justice without focusing on blame or revenge.
Like Aristotle, but without ever mentioning the connection, Nietzsche emphasized a certain sort of character development, and effectively advocated something close to Aristotle’s notion of magnanimity, or “great-souledness” as contrasted with small-mindedness. But in common with some modern interpretations of “virtue ethics”, Nietzsche tended to make whatever a presumably great-souled person might in fact do into a criterion, and consequently downplayed the role of the rational deliberation jointly emphasized by Aristotle and Kant.
Unfortunately, Nietzsche seems to have been so outraged by what he saw as widespread hypocrisy that he sometimes failed to take his own advice to avoid dwelling on the negative. This comes out in his tendency to make sweeping historical generalizations. Thus, he presented all religion in a negative light, and even went so far as to blame the “moralism” of Socrates and Plato for many later historical ills, while failing to note his own partial convergence with Aristotle.
Even at the peak of my youthful enthusiasm for Nietzsche, this negative judgment of Socrates and Plato always seemed wrong to me. Textual evidence just does not support the attribution of primarily “resentful” attitudes to either of them. On the contrary, Socrates and Plato began a completely unprecedented attempt to understand what is good in positive terms, and took great care to avoid prejudice in the process.
Partly as a consequence of his sweeping rejection of Socrates and Plato, Nietzsche looked for alternate heroes among the pre-Socratics, especially favoring Heraclitus. (In the 20th century, with different motivations, Heidegger expanded on Nietzsche’s valorization of the pre-Socratics over Plato and Aristotle, claiming that Heraclitus and Parmenides “had Being in sight” in ways that Plato and Aristotle did not. This seems to me like nonsense. As distinct from poetry and other artistic endeavors (which I value highly, but in a different way), philosophy is not about primordial vision or its recovery; it is about rational understanding and development toward an end, starting from wherever we actually find ourselves. While the pre-Socratics are important in a sort of prehistory of philosophy, the level of rational development they achieved was minimal. Extended rational development first bloomed with Plato, and then was taken to a yet higher level by Aristotle.)
Nietzsche also denied the reality or effective relevance of anything like Aristotelian potentiality, claiming that only what is actual is real. The semantic or expressive category of potentiality underwrites logical and linguistic modality, which among other things in turn underwrites the possibility of expressing objective judgments of “should”, as well as of causality, of which Nietzsche seems to have taken a Humean view. The general role of potentiality and modality is independent of all issues of the correctness or possibly prejudiced character of particular judgments.
Nietzsche’s denial of potentiality is thus related to a denial of any objective good and evil. It is akin to other views that attempt to explain values by facts. He thought mostly in terms of actually occurring valuations, and did distinguish better from worse ones, but mainly in terms of a kind of ad hominem argument from great-souledness or small-mindedness.
In my view, he should have been content to point out that many particular judgments are prejudiced or incorrect, and at any moment we have no sure way of knowing we accurately recognize which these are. Objectivity in ethics cannot be assumed as a starting point, but that does not mean there can never be any. Where it occurs, it is a relative status that is the product of a development. (See also Genealogy.)
Nietzsche’s poetic notion of the Eternal Return does in a way partly make up for his overly strong denial of any objective good or evil. The Eternal Return works especially as an ethical, selective thought that distinguishes purely affirmative valuations from others. I used to want to think this was enough to recover something objective that acts like a notion of good as affirmativeness, but that is contrary to what he says explicitly.
