Abraham Lincoln:
Euclid's first common notion is this: "Things which are equal to the same thing are equal to each other." That's a rule of mathematical reasoning. It's true because it works; has done and will always will do. In his book, Euclid says this is "self-evident." You see, there it is, even in that two-thousand year old book of mechanical law: it is a self-evident truth of things which are equal to the same thing, are equal to each other. We begin with equality. That's the origin, isn't it? That balance-that's fairness, that's justice.
