Hume’s Empiricism
Contrary to rationalism, represented by Descartes, empiricism, emerging in Britain, took the position of explaining mental phenomena on the basis of natural laws discovered empirically.
In order to find a complete system of sciences, David Hume (1711-76) analyzed the mental processes of the human mind objectively, with a new method of finding truth. Through his search for the unchanging, natural laws in the human mind, Hume tried to clarify the foundation of all the sciences, wherein the human mind is involved.
Hume analyzed ideas, which are the elements of the human mind. According to Hume, when simple ideas are associated with each other to bring about complex ideas, there are three principles of association: resemblance, contiguity in time and space, and cause and effect. Among these three, he held that the resemblance of ideas and the contiguity of ideas are sure knowledge, whereas cause and effect is merely a subjective belief.
As a result, Hume’s empiricism fell into skepticism, which asserted that objective knowledge can not be obtained even through inductive inference based on experience and observation. He came to deny all forms of metaphysics and even regarded the natural sciences as insecure.
