One atom in this universe cannot move without dragging the whole world along with it. There cannot be any progress without the whole world following in the wake, and it is becoming every day dearer that the solution of any problem can never be attained on racial, or national, or narrow grounds.
The brutalities of progress are called revolutions. When they are over we realize this: that the human race has been roughly handled, but that it has advanced.
Chemistry ceases to improve when one element is found from which all others are deductible. Physics ceases to progress when one force is found of which all others are manifestations. So religion ceases to progress when unity is reached, which is the case with Hinduism.
To study the meaning of man and of life — I am making significant progress here. I have faith in myself. Man is a mystery: if you spend your entire life trying to puzzle it out, then do not say that you have wasted your time. I occupy myself with this mystery, because I want to be a man.
Science has given to this generation the means of unlimited disaster or of unlimited progress. There will remain the greater task of directing knowledge lastingly towards the purpose of peace and human good.
