Good and evil.

There's no way. My personal opinion is that evil doesn't exist; there is only good. We are often too constrained by our own perceptions to see this good... And that's where these distinctions arise – "good" and "evil," "right" and "wrong"... To be even more precise, they exist at the level of an individual, but not at the level of the world – after all, each of us actually feels what good and evil are. And any sophisticated judgments, that is, their definitions, only obscure the meaning of these words. :)

And one more thing from my creed – no matter how hard we try to mess things up, the world will still turn for the better...
