Chemicals as Instruments: A Language Game
Luigi Cerruti
Meaning is use: Wittgenstein’s well-known dictum is used as start¬ing point for a language game on the English word ‘instrument’ in historical discourse. In this way it is possible to collect a set of words (and correspond¬ing objects) so heterogeneous that the likening ‘chemicals as instruments’ does not seem misplaced. Looking for a better understanding, three classes of chemicals are considered: solvents, indicators, and reagents (just a couple!). The first two classes comprise chemicals, which create new experimental con¬ditions (as the classical air pump), or measure ‘something’ (as the classical thermometer). The third class is more peculiar to chemistry, in that reagents are typical chemical instruments for operating at the microscopic level. In addition, a second language-game is proposed, and it is stressed the deep epistemological difference between physics, which creates ‘phenomena’, and chemistry, which synthesizes substances.
