"My passionate sense of social justice and social responsibility has always contrasted oddly with my pronounced lack of need for direct contact with other human beings and human communities.

On his mental development:

On motivation:
AP
"The ideals that have lighted my way, and time after time have given me new courage to face life cheerfully, have been Kindness, Beauty, and Truth. Without the sense of kinship with men of like mind, without the occupation with the objective world, the eternally unattainable in the field of art and scientific endeavors, life would have seemed empty to me. The trite objects of human efforts possessions, outward success, luxury have always seemed to me contemptible."

On education:
AP
"The aim [of education] must be the training of independently acting and thinking individuals who, however, see in the service to the community their highest life problem."
On ambition:
AP
"Nothing truly valuable arises from ambition or from a mere sense of duty; it stems rather from love and devotion towards men and towards objective things."
