We make our buildings and afterwards they make us. They regulate the course of our lives.

Every man lives in two realms, the internal and the external. The internal is that realm of spiritual ends expressed in art, literature, morals, and religion. The external is that complex of devices, techniques, mechanisms, and instrumentalities by means of which we live.

In the long run of history, destructive means cannot bring about constructive ends.

I refuse to accept the idea that the 'isness' of man's present nature makes him morally incapable of reaching up for the eternal 'oughtness' that forever confronts him.

One of the great philosophical debates of the centuries has been over the whole question of ends and means. In a real sense, the end is pre-existent in the means; the means represent the ideal in the making, and the end in process. In the long run of history, immoral means cannot bring about moral ends.

The trouble isn't so much that our scientific genius lags behind, but our moral genius lags behind. The great problem facing modern man is that, that the means by which we live have outdistanced the spiritual ends for which we live.
