““For if we understood or said that colour is not in a coloured body, or that it is separated from it, there would be error in this opinion or assertion. But if we consider colour and its properties, without reference to the apple which is coloured; or if we express in words what we thus understand, there is no error in such an opinion or assertion, because an apple is not essential to colour, and therefore, colour can be understood independently of the apple.””
