The Two Uses of Language
The relative importance o f the two sets o f factors varies enor mously. A sufficiently hungry man will eat almost anything which can be chewed or swallowed. The nature o f the sub stance, within these limits, has very little effect upon his behav iour. A replete person, by contrast, will only eat such things as he expects will taste pleasant, or regards as possessing definite ben eficial properties, for example, medicines. His behaviour, in other words, depends almost entirely upon the character o f his optical or olfactory stimulation.
