Gilbert actually treats the essential and accidental features of a thing as being on a par, at least as far as individuation goes.8 All of them are possessed as singular features, and serve as parts of the total form that guarantees individuality. Also, unlike his predecessors and contemporaries, Gilbert does not confuse the question of what makes something individual with the question of how we know something is individual. He sees clearly that accidents merely show us that one individual is distinct from another, without making it be distinct (non facit, sed probat).9
