Monist

Monism is the view that attributes oneness or singleness (Greek:μόνος) to a concept (e.g., existence). Substance monism is the philosophical view that a variety of existing things can be explained in terms of a single reality or substance. Another definition states that all existing things go back to a source that is distinct from them (e.g., in Neoplatonism everything is derived from The One). This is often termed priority monism, and is the view that only one thing is ontologically basic or prior to everything else.

Another distinction is the difference between substance and existence monism, or stuff monism and thing monism. Substance monism posits that only one kind of stuff (e.g., matter or mind) exists, although many things may be made out of this stuff. Existence monism posits that, strictly speaking, there exists only a single thing (e.g., the universe), which can only be artificially and arbitrarily divided into many things.

There are two sorts of definitions for monism:

Although the term "monism" is derived from Western philosophy to typify positions in the mind–body problem, it has also been used to typify religious traditions. In modern Hinduism, the term "absolute monism" is being used for Advaita Vedanta.

The term "monism" was introduced in the 18th century by Christian von Wolff in his work Logic (1728), to designate types of philosophical thought in which the attempt was made to eliminate the dichotomy of body and mind and explain all phenomena by one unifying principle, or as manifestations of a single substance.

The mind–body problem in philosophy examines the relationship between mind and matter, and in particular the relationship between consciousness and the brain. The problem was addressed by René Descartes in the 17th century, resulting in Cartesian dualism, and by pre-Aristotelian philosophers, in Avicennian philosophy, and in earlier Asian and more specifically Indian traditions.

It was later also applied to the theory of absolute identity set forth by Hegel and Schelling. Thereafter the term was more broadly used, for any theory postulating a unifying principle. The opponent thesis of dualism also was broadened, to include pluralism. According to Urmson, as a result of this extended use, the term is "systematically ambiguous".
