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.
Ludwig BuchnerThe 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.
Ludwig BuchnerWe are sorry to confess that biological hypotheses have not yet completely got out of the second phase, and that ghost of โvital forceโ still haunts many wise heads.
