The Human being (n.) is a synthesis of the infinite and finite, of the temporal and the eternal, of freedom and necessity.
A Human being (n.) is 'what we all know', by Democritus' definition — from which Sextus Empiricus wittily concludes that a human being is a dog.

The Human being (n.) must be found while one is young; Diogenes with his lantern by day should not be mocked, for whoever has not found a man in youth may need one.
Human being (n.) is not lower than the distinctions we invent but high above them: at the solemn moment, and at death, we say not 'Your Majesty' but simply 'Man!'
