reductionism

the doctrine that, either in practice or in principle, the propositions of one science can be explained in terms of the propositions of another, e.g. the reduction of chemistry to physics, or the reduction of sociology to psychology.

The contrasting doctrine is that particular sciences may be irreducible to other sciences. For Durkheim, for example, social reality is an ‘emergent’ reality, a reality sui generis irreducible to other sciences such as psychology. Similarly, those sociologists who emphasize human meanings as the basis of social explanations also see this level of analysis as irreducible. In practice, the relationships between the sciences are complex, with no pattern, or view of the pattern, of these relationships being in the ascendancy. Sometimes the subject matter of one science can be illuminated by analogies with, or reduction to, another; at other times attempted reductions of analogies will be misplaced or misleading.
