Moral philosophy

Virtue and Knowledge

The Socratic-Platonic claim that virtue is a kind of knowledge — that no one does wrong willingly, that to know the good is to do it, and that vice is a form of ignorance — and the long debate it provoked.

The Socratic identity

The claim that virtue is a kind of knowledge is the heart of Socratic ethics and the foundation of Plato's moral philosophy. The platform reads it as one of the most consequential and most disputed ideas in the history of thought: that to know the good truly is to do it, that no one does wrong willingly (the "Socratic paradox"), and that vice is therefore a form of ignorance rather than wickedness. If a person genuinely knew that an action was bad for them — bad for their soul, the most important thing they have — they could not, on this view, choose it.

What follows

The platform reads the consequences of this claim as far-reaching. If virtue is knowledge, then it can in principle be taught and learned — the question the Meno pursues — and the central task of ethics becomes the pursuit of the knowledge of the good, which is the task of philosophy itself. It also means that the wrongdoer is to be pitied and corrected rather than merely punished, since he acts from ignorance; and that the philosopher, who alone possesses the knowledge of the good, is alone fully virtuous and alone fit to rule. The platform reads the whole structure of Platonic politics as resting on this ethical foundation.

The objection

The platform reads the permanent objection as the phenomenon of akrasia — weakness of will, acting against one's own better judgement. We seem, constantly, to know the good and fail to do it, choosing the worse while seeing the better. Aristotle would take this objection seriously, arguing that virtue requires not only knowledge but the habituation of desire and the training of character, so that one comes to want the good and not merely to know it. The platform reads this as one of the deepest divisions between Plato and Aristotle: whether virtue is finally a matter of knowledge or of formed character.

Why it matters for Virtue & Power

Virtue and knowledge is the ethical root of Plato's entire system — the ground of his theory of education, justice and rule — and one of the platform's central moral-philosophical themes. It is the legacy of Socrates in Plato, read in the legacy of Socrates in Plato, and the point on which the platform's reading of virtue ethics turns.
