Our topic now is justice, in two senses:
- Lawfulness.
- Equity.
That doesn’t mean we’re talking about equality before the law. Instead of lawfulness and equity, we might refer to morality and fairness. What we are really trying to do is understand what Aristotle means, when he says that “the dikaion” (τὸ δίκαιον) is one of the following:
- “The nomimon” (τὸ νόμιμον).
- “The ison” (τὸ ἴσον).
Why would we want to do understand this? Well, that last Greek word appears as a suffix in isoskeles (ἰσοσκελής), which has become our word “isosceles” for the same thing. The ison is the equal. A triangle is isosceles when two of its legs are equal. Each of those legs is a skelos (σκέλος), while the remaining side is the basis (βάσις), the base.
