A. There aren't any 'general ideas'. | B. General ideas are innate | ||
C. General ideas are formed by subtracting from a set of particular ideas the elments that the members don't have in common | D. The only truly general ideas are ideas of numbers, and this is why mathematics is so central to knowledge | ||
Berkeley thinks we make general judgements in virtue of using particular ideas in a special way.
C. is the position he was attacking - Locke's.
He didn't think there were any general ideas - just particular ideas which could be used on occasion to stand for others.
So both B. and D. are mistaken, leaving A. as the correct answer.
