Positivism is a theory of knowledge according to which the only kind of sound knowledge available to human kind is that if science grounded in observation.

nd now that man's history has been for the first time systematically considered as a whole, and has been found to be, like all other phenomena, subject to invariable laws, the preparatory labours of modern Science are ended.

Nothing is destroyed until it is replaced.

All good intellects have repeated, since Bacon's time, that there can be no real knowledge but which is based on observed facts.

Every science consists in the coordination of facts; if the different observations were entirely isolated, there would be no science.

The sacred formula of positivism: love as a principle, the order as a foundation, and progress as a goal.

If we do not allow free thinking in chemistry or biology, why should we allow it in morals or politics?
