Empiricism is a theory that states that knowledge comes only or primarily from sensory experience.[1] Empiricism emphasizes the role of empirical evidence in the formation of ideas, over the idea of innate ideas or traditions;[2] empiricists may argue however that traditions (or customs) arise due to relations of previous sense experiences.[3] Empiricism in the philosophy of science emphasizes evidence, especially as discovered in experiments. It is a fundamental part of the Scientific Method that all hypotheses and theories must be tested against observations of the natural world rather than resting solely on a priori reasoning, intuition, or revelation. https://en.wikipedia.org/wiki/Empiricism
