Despite the large number of philosophical schools and subtle nuances between many, all philosophies are said to fall into one of two primary categories, which are defined in contrast to each other: Idealism, and materialism. The basic proposition of these two categories pertains to the nature of reality, and the primary distinction between them is the way they answer two fundamental questions: "what does reality consist of and how does it originate?" To idealists, spirit or mind is primary, and created matter secondary. To materialists, matter is primary and mind or spirit is secondary, a product of matter acting upon matter.

The materialist view is perhaps best understood in its opposition to the doctrines of immaterial substance applied to the mind historically, famously by René Descartes

Schopenhauer wrote that "...materialism is the philosophy of the subject who forgets to take account of himself". He claimed that an observing subject can only know material objects through the mediation of the brain and its particular organization. The way that the brain knows determines the way that material objects are experienced. "Everything objective, extended, active, and hence everything material, is regarded by materialism as so solid a basis for its explanations that a reduction to this (especially if it should ultimately result in thrust and counter-thrust) can leave nothing to be desired. But all this is something that is given only very indirectly and conditionally, and is therefore only relatively present, for it has passed through the machinery and fabrication of the brain, and hence has entered the forms of time, space, and causality, by virtue of which it is first of all presented as extended in space and operating in time."

Marx and Engels used the term "materialism" to refer to a theoretical perspective that holds the satisfaction of everyday economic needs is the primary reality in every epoch of history. Opposed to German idealist philosophy, materialism takes the position that society and reality originate from a set of simple economic acts which human beings carry out in order to provide the material necessities of food, shelter, and clothing. Materialism takes as its starting point that before anything else, human beings must produce their everyday economic needs through their physical labor and practical productive activity. This single economic act, Marx believed, gives rise to a system of social relations which include political, legal and religious models usually intended to facilitate this process or justify the current social system in existence.

Defining matter

The nature and definition of matter - like other key concepts in science and philosophy - have occasioned much debate. Is there a single kind of matter which everything is made of (hyle

), or is it lacking them (prima materia)?

One challenge to the traditional concept of matter as tangible "stuff" came with the rise of field physics in the 19th century. However the conclusion that materialism is false may be premature. Relativity

. But if the definition of "matter" is extended to "anything whose existence can be inferred from the observed behaviour of traditional matter" then there is no reason in principle why entities whose existence materialists normally deny should not be considered as "matter".

While it is believed by many physical scientists that the concept of matter has merely changed, rather than being eliminated, some have taken a more extreme position. For instance Werner Heisenberg
