Karl Popper

He was a Austrian philosopher, sociologist and science theorist born in 1902, he is considered to be a critic rationalist, he meant that reason gets to a confidence vote but to do this we need to verify the content empirically. For him the Scientific Knowledge is true knowledge but could be wrong, it is not certain.




He expose his vision of the science of philosophy in his work, Logic of Scientific Discovery, he takes the problem of limits between the science and metaphysics, and proposes the search of a Demarcation Problem, to distinguish the scientific propositions of those that aren't. This statement does not decides of the truth or falsity of a proposition, but if can be studied in science, or in metaphysics.














Critic Method: the scientific knowledge is always hypothetical, its mainly localize the mistakes to get the truth, science shouldn't be based on faith, but in reason.




Principle of Falsifiability: in order to a theory to be called as a "scientific", it needs to be fasifiable, the promoter has to prove it with reality to get to the final conclusion, validate it o refute it.




Scientific Theories, are not definitive, is always latent the possibility to find new facts or new discovers, to make a new conclusion and postulate other theory.
