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.
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.
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.
Our words must be judged by our deeds; and in striving for a lofty ideal we must use practical methods; and if we cannot attain all at one leap, we must advance towards it step by step, reasonably content so long as we do actually make some progress in the right direction.
The reasonable man will adjust to the demands of his environment. The unreasonable man expects his environment to adjust to his own needs. Therefore, all progress depends upon the unreasonable man.
