Doubts are good. Confusion is excellent. Questions are awesome.
All these are attempts to expand the wisdom of mind.

Many life-affirming questions lead to an endless spool of disconcerting propositions and contradictory conclusions, and even more troubling, some queries prove unanswerable.

a fool has questions, a wise has answers...

One who sharpens his sword before sharpening his mind has already been conquered by ignorance.

All people share doubts. The lingering question that eventually worms it way into all thinking people’s brain is how to live splendidly and how to die without remorse and regret.

Mind knows the questions, soul knows the answers.
