The infinite wonders of the universe are revealed to us in exact measure as we are capable of receiving them. The keenness of our vision depends not on how much we can see, but on how much we feel.

Personally I do not believe in a national agency devoted only to the negro blind because in spirit and principle I am against all segregation, and the blind already have difficulties enough without being cramped and harassed by social barriers.

We need limitations and temptations to open our inner selves, dispel our ignorance, tear off disguises, throw down old idols, and destroy false standards. Only by such rude awakenings can we be led to dwell in a place where we are less cramped, less hindered by the ever-insistent External. Only then do we discover a new capacity and appreciation of goodness and beauty and truth.

The highest thinkers of the ages, the seers of the tribes and the nations, have been optimists.
