What is positivist philosophy?

Positivism is a philosophical school that rose in the late19th century. It is one of the early schools of western modern philosophy contemporary with Marxism. Its main idea is to oppose Hegel's deduction of a set of irrelevant dialectics, but to inherit the British empiricism tradition, thinking that only knowledge that has been proved by practice is reliable knowledge, and philosophy should be based on this knowledge.

The so-called "people can never prove that a scientific theory is correct" is actually a proposition that existed before positivism. The philosophical term is "Hume's puzzle", which means that individual experiments can't prove universal truth (that is, even if an experiment succeeds a hundred times and a thousand times, it can't be said that it proves an inevitable truth, and there is a huge logical fault here). While inheriting the British empiricism tradition, positivism also faces the dilemma of empiricism, that is, Hume's problem. As long as Hume's problem is not solved, we can never say that the scientific theory we have mastered through experiments is inevitable, that is to say, we can't prove the truth of any theory.
