Intelligence is not the ability to store information, but to know where to find it.

If you want your children to be smart, tell them stories. If you want them to be really smart, tell them more stories. If you want your children to be brilliant, tell them even more stories.

I do not like to state an opinion on a matter unless I know the precise facts.

Freedom of teaching and of opinion in book or press is the foundation for the sound and natural development of any people.

From the standpoint of daily life, however, there is one thing we do know: that we are here for the sake of each other - above all for those upon whose smile and well-being our own happiness depends, and also for the countless unknown souls with whose fate we are connected by a bond of sympathy. Many times a day I realize how much my own outer and inner life is built upon the labors of my fellow men, both living and dead, and how earnestly I must exert myself in order to give in return as much as I have received.

I have not eaten enough of the tree of knowledge, though in my profession I am obligated to feed on it regularly.

It seems to me that the idea of a personal God is an anthropological concept which I cannot take seriously. I also cannot imagine some will or goal outside the human sphere... Science has been charged with undermining morality, but the charge is unjust. A man's ethical behavior should be based effectually on sympathy, education, and social ties and needs; no religious basis is necessary. Man would indeed be in a poor way if he had to be restrained by fear of punishment and hope of reward after death.
