In order to understand people, we have to understand their way of life and approach. If we wish to convince them, we have to use their language in the narrow sense of the mind. Something that goes even much further than that is not the appeal to logic and reason, but some kind of emotional awareness of the other people.

Act with courage and dignity; stick to the ideals that give meaning to life.

Every little thing counts in a crisis.

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

Science and technology have freed humanity from many burdens and given us this new perspective and great power. This power can be used for the good of all. If wisdom governs our actions; but if the world is mad or foolish, it can destroy itself just when great advances and triumphs are almost without its grasp.

The future belongs to science and those who make friends with science.

Time is not measured by the passing of years but by what one does, what one feels, and what one achieves.
