Remember always that there not so very much difference between various people as we seem to imagine. Maps and atlases show us countries in different colors. Undoubtedly people do differ from one another, but they resemble each other also a great deal, and it is well to keep this in mind and not misled by colors on the map or by national boundaries.

It is science alone that can solve the problems of hunger and poverty, of insanitation and illiteracy, of superstition and deadening custom and tradition, of vast resources running to waste, or a rich country inhabited by starving people... Who indeed could afford to ignore science today? At every turn we have to seek its aid... The future belongs to science and those who make friends with science.

What the mysterious is I do not know. I do not call it God because God has come to mean much that I do not believe in. I find myself incapable of thinking of a deity or of any unknown supreme power in anthropomorphic terms, and the fact that many people think so is continually a source of surprise to me. Any idea of a personal God seems very odd to me.

When the present is full of gloom, the past becomes haven of refuge that provides relief and inspiration.

Unity must be of the mind and heart, a sense of belonging together and of facing together those who attack it.

Action to be effective must be directed to clearly conceived ends.
