In
philosophy generally, empiricism is a
theory of knowledge emphasizing the role of
experience, especially
sensory perception, in the formation of ideas, while discounting the notion of
innate ideas.In the
philosophy of science, empiricism is a theory of knowledge which emphasizes those aspects of scientific knowledge that are closely related to experience, especially as formed through deliberate experimental arrangements. It is a fundamental requirement of
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. Hence, science is considered to be methodologically empirical in nature.
