One of the most interesting and harmful delusions to which men and nations can be subjected is that of imagining themselves special instruments of the Divine Will.

Life and hope for the world are to be found only in the deeds of love.

Without effort and change, human life cannot remain good. It is not a finished Utopia that we ought to desire, but a world where imagination and hope are alive and active.

Machines have altered our way of life, but not our instincts. Consequently, there is maladjustment.

If a man is offered a fact which goes against his instincts, he will scrutinize it closely, and unless the evidence is overwhelming, he will refuse to believe it. If, on the other hand, he is offered something which affords a reason for acting in accordance to his instincts, he will accept it even on the slightest evidence. The origin of myths is explained in this way.

Science may set limits to knowledge, but should not set limits to imagination.

The mind is a strange machine which can combine the materials offered to it in the most astonishing ways.
