 Talk about the use of an expression, like the use of safety-pins and table-knives, helps us to avoid thinking that we are talking about any queer relations or queer entities; to suppose or half-suppose that “studying the meaning of the phrase ‘the solar system’ [is] … the same thing as studying the solar system” (1953, 306). It reminds us, for example, that when enquiring into the problems of perception or in discussing the concepts of seeing, hearing, and smelling, we are not tackling the questions of opticians, neuro-physiologists or psychologists. We are rather after accounts of how certain words work, “namely words like ‘see’, ‘look’, ‘overlook’, ‘blind’, ‘visualise’, and lots of other affiliated expressions” (1953, 317).
