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.

Nothing is destroyed until it is replaced.

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

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