"Learning is not attained by chance, it must be sought for with ardor and diligence" — Abigail Smith Adams

Erudition can produce foliage without bearing fruit.

The visible mark of extraordinary wisdom and power appear so plainly in all the works of creation

The only fence against the world is a thorough knowledge of it

I have studied many philosophers and many cats. The wisdom of the cats is infinitely superior.

A book is a mirror: If an ass peers into it, you can't expect an apostle to look out

One's first step in wisdom is to question everything - and one's last is to come to terms with everything
