Abstract
Early in the Nicomachean Ethics Aristotle writes, “It is a common principle which must be accepted that we must act in accord with orthos logos. What orthos logos is will be discussed later”. Although scholars have pored over Aristotle’s Ethics for centuries and can paraphrase what he says about orthos logos, obscurity remains as to just what he understands by it. This obscurity can be dispelled by focusing once again on those few sections in Aristotle familiar to all students of the Ethics which bear most directly upon the topic. Aristotle explains what he understands by orthos logos in the context of being good at deliberating. Since he frequently illustrates deliberating by instances of deliberation in the practice of an art, we may first examine what he has to say about deliberating in such a context.
