A Research of Popper’s View of Scientific Knowledge

Popper’s view of Knowledge shows in three aspects. The first is the division of scientific knowledge. Scientific knowledge is always hypothetic. Suppose that people can regulate a judging experiment, which can falsify theories. Then the theory is scientific; It is suppose that it is refused to regulate the potential falsifier, then the theory is false scientific. The second is the growing of scientific knowledge. New questions can cause creature or composer, which can add new object to the third world of knowledge. Every step can bring about new and unexpected facts and also new refutation. The last is the evaluation and criterion of scientific knowledge. The criterion of a theory is not the evidence that it has gained, but is the degree of its falsification and the strictness of its testing. Confirmation degree has nothing to do with the true and false, but only shows the appropriateness degree of people,s temporarily accepting a conjecture with questions.
