but you will call it sour, its quality is sour, and that is a fact. if u cook, and u dont put enoug spices in the food, its quality is bland, and that is a fact at that time, u can add some spices later and its quality will be spicy and that will be a fact at that time.
it is ok u dont ahve to argue with nai-rosnhi student. because she believes that there is no hope is alloted with "Facts", as they are there whether we believe them or not.
whereas in this apple case, quality is deciphering the nature of that specific apple, which changes everything.....but facts dont change.
ps. it is always good to separate allegories with qualities.
