Logic is like the sword - those who appeal to it, shall perish by it.
Man has such a predilection for systems and abstract deductions that he is ready to distort the truth intentionally, he is ready to deny the evidence of his senses only to justify his logic.
From a drop of water a logician could infer the possibility of an Atlantic or a Niagara without having seen or heard of one or the other.
The want of logic annoys. Too much logic bores. Life eludes logic, and everything that logic alone constructs remains artificial and forced.
Logic is one thing, the human animal another. You can quite easily propose a logical solution to something and at the same time hope in your heart of hearts it won't work out.
A mind all logic is like a knife all blade. It makes the hand bleed that uses it.
The fact that logic cannot satisfy us awakens an almost insatiable hunger for the irrational.
