 Reznek, for instance, argues that to judge “that homosexuality is a disease we first have to make a value-judgment. We have first to judge that we would be worse off being homosexual” (1987, 212). Reznek then says that we could discover that homosexuality is not a disease if we find out that it develops by a normal psychological process. Reznek calls this is a form of constructivism (or normativism, in his terms) because value judgments have conceptual priority: but in fact in the case he describes it seems that value judgments are actually only heuristics, drawing our attention to whether something might be wrong with someone. If the initial judgment can be overturned by a biological discovery, then it seems that biological facts are necessary for a final judgment. That is to say that our concept of disease necessarily involves both biological and evaluative judgments. That is a version of naturalism, since the biological facts are the ultimate foundation for the judgment. Indeed, naturalism seems to explain why constructivist interpretations are sometimes correct. We say now that homosexuality was never a disease, and was just diagnosed on moral grounds, because it was not caused by malfunctions according to any even moderately correct theory of human biology or psychology. Values stopped people from getting the science right, but homosexuality was correctly understood, and no longer seen as a disease, when the science was done in a properly disinterested way.
