From Wikipedia
In philosophy, empiricism is an epistemological theory that holds that knowledge or justification comes only or primarily from sensory experience.[1] It is one of several views within epistemology, along with rationalism and skepticism. Empiricism emphasizes the central role of empirical evidence in the formation of ideas, rather than innate ideas or traditions.[2] However, empiricists may argue that traditions (or customs) arise due to relations of previous sensory experiences
