Theory-Practice Dichotomy
[Consider the catch phrase:] “This may be good in theory, but it doesn’t work in practice.” What is a theory? It is a set of abstract principles purporting to be either a correct description of reality or a set of guidelines for man’s actions. Correspondence to reality is the standard of value by which one estimates a theory. If a theory is inapplicable to reality, by what standard can it be estimated as “good”? If one were to accept that notion, it would mean: a. that the activity of man’s mind is unrelated to reality; b. that the purpose of thinking is neither to acquire knowledge nor to guide man’s actions. (The purpose of that catch phrase is to invalidate man’s conceptual faculty.)
