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.

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

Loyal and efficient work in a great cause, even though it may not be immediately recognized, ultimately bears fruit.

People avoid action. Often because they are afraid of the consequences, for action means risk and danger. Danger seems terrible from a distance; it is not so bad if you have a close look at it

Let us be a little humble; let us think that the truth may not perhaps be entirely with us.

What we really are matters more than what other people think of us.
