John Locke is the founding father of this concept. What is Empiricism?

Empiricism is particularly about the subject to reject the corresponding version of Intuition or deduction. In so far we know our subject our knowledge is posterior dependent on the sense of experience. Empiricists even deny the implication of innate concepts such as innate ideas in the subject area. They have been rejecting the corresponding version of the superiority of reason. As we know that reason alone not provide us knowledge, it doesn't give us superior knowledge. They generally reject the indispensability of reason. It suggests that knowledge can only be gained by experience. No one clearly explained the empiricism concept properly. When it comes to nature, the world beyond our reach, the experience is our sole source of information. The reason might inform us about relations among ideas are only based on the sense of experience.

the theory that all knowledge is derived from sense-experience. Stimulated by the rise of experimental science, it developed in the 17th and 18th centuries, expounded in particular by John Locke, George Berkeley, and David Hume.
