Ethical metaphysics is fundamentally an attempt, however disguised, to give legislative force to our own wishes

If everything must have a cause, then God must have a cause. If there can be anything without a cause, it may just as well be the world as God, so that there cannot be any validity in that argument

No great achievement is possible without persistent work.

Reason is a harmonising, controlling force rather than a creative one.

Our mental make-up is suited to a life of very severe physical labor

The world that we must seek is a world in which the creative spirit is alive, in which life is an adventure full of joy and hope, based rather upon the impulse to construct than upon the desire to retain what we possess or to seize what is possessed by others.
