The useless search of philosophers for a cause of the universe is a regressus in infinitum (a stepping backwards into the infinite) and resembles climbing up an endless ladder, the recurring question as to the cause of the cause rendering the attainment of a final goal impossible.

We are sorry to confess that biological hypotheses have not yet completely got out of the second phase, and that ghost of ‘vital force’ still haunts many wise heads.

The universe, as we see it, is the result of regularly working forces, having a causal connection with each other and therefore capable of being understood by human reason.

For the thinker the world is a thought; for the wit, an image; for the enthusiast, a dream; for the inquirer, truth.

A creative force that either creates itself or arises from nothing, and which is a causa sui (its own cause), exactly resembles Baron Munchhausen, who drew himself out of the bog by taking hold of his own hair.

Death is the surest calculation that can be made.
