על השיכרות מ״וOn Drunkenness 46
א׳
1[190] For instance, how do we apprehend colours? Surely by means of the externals, air and light, and the internal moisture in the eye itself. How do we discriminate between sweet and bitter? Can we do so without the juices in the mouth, both those which are in accord with nature and those which are not? Surely not. Again, do the odours produced by burning incense present to us the natures of the substances in a pure and simple form, or in a combination, in which themselves and air, or sometimes also the fire which dissolves the material, are joined with the faculty possessed by the nostrils?
ב׳
2[191] From this we deduce that we do not apprehend colours, but only the combination produced by the light and the material substances to which the colours belong, nor smells, but only the mixture of the emanation from the substances with the all-admitting air; nor flavours, but only the something produced by the application of what we taste to the moisture in our mouths.
