The highest form of bliss is living with a certain degree of folly.

Where ignorance is bliss, 'Tis folly to be wise.

Now I believe I can hear the philosophers protesting that it can only be misery to live in folly, illusion, deception and ignorance, but it isn't -it's human.

Human folly does not impede the turning of the stars.

The most exquisite folly is made of wisdom too fine spun

A fool and a wise man are alike both in the starting-place--their birth, and at the post--their death; only they differ in the race of their lives.
