The opposite of reductionism is

holism Holism () is the idea that various systems (e.g. physical, biological, social) should be viewed as wholes, not merely as a collection of parts. The term "holism" was coined by Jan Smuts in his 1926 book '' Holism and Evolution''."holism, n." OED O ...

, a word coined by Jan Smuts in Holism and Evolution, that understanding a system can be done only as a whole. One form of antireductionism (epistemological) holds that we simply are not capable of understanding systems at the level of their most basic constituents, and so the program of reductionism must fail. The other kind of antireductionism (ontological) holds that such a complete explanation in terms of basic constituents is not possible even in principle for some systems. Robert Laughlin, e.g. supports this view. Disciplines such as cybernetics and systems theory embrace a non-reductionist view of science, sometimes going as far as explaining phenomena at a given level of hierarchy in terms of phenomena at a higher level, in a sense, the opposite of a reductionist approach. Although breaking complex phenomena into parts is a key method in science, there are those complex phenomena (e.g. in physics, psychology, sociology, ecology) where the approach does not work. Antireductionism also arises in academic fields such as history, economics, anthropology, medicine, and biology as attempts to explain complex phenomena using reductionist models do not provide satisfactory insight.

Most reductionists accept that consciousness ''seems'' to be different from brain states (or functions) but claim that science will ''discover'' it to be nothing more than a state or function of the brain. In short, they mostly accept that brains states and conscious states are ''conceivably'' different, but deny that they are ''actually'' different (in the universe we happen to inhabit)Max Velmans; ''Understanding consciousness'', Note 26, page 262.

Velmans himself is not in agreement with this reductionist stance. Opposition to this ''mind = brain'' reductionism is found in many authors. An often mentioned issue is that science cannot explain the

However, others find that the conflict between reductionism and antireductionism is "one of the central problems in the philosophy of psychology...an updated version of the old mind-body problem: how levels of theories in the behavioral and brain sciences relate to one another. Many contemporary philosophers of mind believe that cognitive-psychological theories are not reducible to neurological theories...most nonreductive physicalists prefer the idea of a one-way dependence of the mental on the physical."
