Deeds

Don’t listen to their words, fix your attention on their deeds.

I am absolutely convinced that no wealth in the world can help humanity forward, even in the hands of the most devoted worker in this cause. The example of great and pure characters is the only thing that can produce fine ideas and noble deeds. Money only appeals to selfishness and always tempts its owners irresistibly to abuse it

I think we have to safeguard ourselves against people who are a menace to others, quite apart from what may have motivated their deeds.

If you want to find out anything from the theoretical physicists about the methods they use, I advise you to stick closely to one principle: don’t listen to their words, fix your attention on their deeds. To him who is a discoverer in this field the products of his imagination appear so necessary and natural that he regards them, and would like to have them regarded by others, not as creations of thought but as given realities.

It is every man’s obligation to put back into the world at least the equivalent of what he takes out of it.
