Idealism, material and soul are three concepts on the focus of discussions in the history of thought. It is difficult to maintain a discussion in the history of philosophy by leaving out either the material or the soul in particular. When we talk about philosophers, we categorize them as materialists or spiritualists from time to time. This categorization contains a reference to the philosopher's ontology and epistemology.
