'That which is actually found in the phantasms' is 'definite likenesses of the natures of sensible things.' The objection may be raised, than when these likenesses are 'dematerialised,' all likeness to sensible material things is lost. The answer, I take it, is that 'dematerialising' means only 'universalising'. I have a universal idea of a rainbow without blinding my mind's eye to its colours.
