Genius is not inspired. Inspiration is perspiration.

Sticking to it is the genius.

One may certainly admire man as a mighty genius of construction, who succeeds in piling an infinitely complicated dome of concepts upon an unstable foundation, and, as it were, on running water.

True genius resides in the capacity for evaluation of uncertain, hazardous, and conflicting information.

One must indeed be ignorant of the methods of genius to suppose that it allows itself to be cramped by forms.

Adversity is the midwife of genius.
