What was nous?
Nous referred to the intellect or the faculty of understanding — the part of the mind that grasps truth directly. It sat at the very heart of Greek ideas about reason.
How did Aristotle distinguish wisdom?
Aristotle separated sophia (theoretical wisdom about universal truths) from phronesis (practical wisdom about how to act well). He regarded both as genuine forms of excellence of mind.
Why does practical wisdom matter?
Phronesis is the capacity to make good decisions in real, messy situations. Aristotle saw it as essential to a flourishing life — something raw cleverness alone can never replace.
How does this influence us today?
The Greek distinction between knowing facts and knowing how to live wisely still shapes debates about whether an IQ score captures everything that matters about the human mind.
