Never let an inventor run a company. You can never get him to stop tinkering and bring something to market

The generosity of the Earth allows us to feed all mankind; we know enough about ecology to keep the Earth a healthy place; there is enough room on the Earth, and there are enough materials, so that everybody can have adequate shelter; we are quite competent enough to produce sufficient supplies of necessities so that no one need live in misery.

There are three things healthy people most need to do - to be creatively productive, to render service, and to act in accordance with their moral impulses. In all three respects modern society frustrates most people most of the time.

It might be said that it is the ideal of the employer to have production without employees and the ideal of the employee is to have income without work.

I have no doubt that it is possible to give a new direction to technological development, a direction that shall lead it back to the real needs of man, and that also means: to the actual size of man. Man is small, and, therefore, small is beautiful.

There can be nothing sacred in something that has a price.

Our task - and the task of all education - is to understand the present world, the world in which we live and make our choices.
