in some cases, it may be that practices grow to support each other, a notion he called 'coadaptation', deriving from the biological term. Functional analysis, then, was just the attempt to explain stability by discovering how practices fit together to sustain that stability; the 'function' of practice was just its role in sustaining the overall social structure, insofar as there was a stable social structure (Radcliffe-Brown 1957). This is far from the 'functional explanation' later impugned by Carl Hempel and others. It is also clearly distinct from Malinowski's notion of function, a point which is often ignored by Radcliffe-Brown's detractors. "Malinowski has explained that he is the inventor of functionalism, to which he gave its name. His definition of it is clear; it is the theory or doctrine that every feature of culture of any people past or present is to be explained by reference to seven biological needs of individual human beings. I cannot speak for the other writers to whom the label functionalist is applied by the authors, though I very much doubt if Redfield or Linton accept this doctrine. As for myself I reject it entirely, regarding it as useless and worse. As a consistent opponent of Malinowski's functionalism I may be called an anti-functionalist." Concept of social structure While Lévi-Strauss (1958) claimed that social structure and the social relations that are its constituents are theoretical constructions used to model social life, Radcliffe-Brown only half-agreed "to say we are studying social structures is not exactly the same thing as saying that we study social relations, which is how some sociologists define their subject. A particular social relation between two persons (unless they be Adam and Eve in the Garden of Eden) exists only as part of a wide network of social relations, involving many other persons, and it is this network which I regard as the object of our investigations. "I am aware, of course, that the term "social structure" is used in a number of different senses, some of them very vague. This is unfortunately true of many other terms commonly used by anthropologists. The choice of terms and their definitions is a matter of scientific convenience, but one of the characteristics of a science as soon as it has passed the first formative period is the existence of technical terms which are used in the same precise meaning by all the students of that science.
