In short ...

... Nassim Nicholas Taleb's Poetic & Philosophical Aphorisms. (Hat tip, Dave Lull.)

All seem interesting, many are obviously debatable, but no less interesting for that. A sample:

Hatred is much harder to fake than love. You hear of fake love; never of fake hate.

This is a kind of corollary to Jacques Brel's explanation of why he never wrote love songs - that love can be faked, but tenderness cannot.
