“…In physics, quantum theory (e.g., Bohr, 1963;Bohm, 1980) has illuminated a relationship between the observed and the method of observation-the latter playing a fundamental role in constructing the former. 4 In biology, the theory of evolution has been revised to embrace the idea that organisms co-construct their world rather than passively adapt to it, resulting in the conclusion that or~anisms are inevitably a part of what they observe, not separate from I it [see Margulis and Sagan (1987), Lovelock (1988) and Ho (1989) for some general accounts]. Finally, in psychology, scientists have' argu~d that much of what human beings assume is factual is actually what is socially relevant within a particular discursive context (e.g., Middleton and Edwards, 1990;Gergen, 1991;Shotter, 1993;Harre and Gillett, 1994).…”
