John Locke, a leading philosopher of British empiricism

Empiricism is a theory that states that knowledge comes only or primarily from sensory experience.<ref>{{#invoke:citation/CS1|citation |CitationClass=book }}</ref> One of several views of epistemology, the study of human knowledge, along with rationalism and skepticism, empiricism emphasizes the role of experience and evidence, especially sensory experience, in the formation of ideas, over the notion of innate ideas or traditions;<ref>{{#invoke:citation/CS1|citation |CitationClass=book }}{{ safesubst:#invoke:Unsubst||$N=Page needed |date=__DATE__ |$B= {{#invoke:Category handler|main}}{{#invoke:Category handler|main}}[page needed] }}</ref> empiricists may argue however that traditions (or customs) arise due to relations of previous sense experiences.<ref>Hume, David.

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.

Empiricism, often used by natural scientists, says that "knowledge is based on experience" and that "knowledge is tentative and probabilistic, subject to continued revision and falsification."<ref>Shelley, M. (2006). Empiricism. In F. English (Ed.), Encyclopedia of educational leadership and administration. (pp. 338-339). Thousand Oaks, CA: SAGE Publications, Inc.</ref> One of the epistemological tenets is that sensory experience creates knowledge. The scientific method, including experiments and validated measurement tools, guides empirical research.
