To say that a philosophy is not good because it has been refuted is like saying that the soccer game was pointless because neither team scored a goal despite playing very hard. All the important philosophies in the world have been attacked and refuted several times—but that has actually strengthened these philosophies, enabling them to dominate our culture and politics. Philosophical criticism makes a philosophy relevant by placing it in the historical context. The worst thing that can happen to a philosophy is neglect by other schools. For instance, the 20th century philosophy of Existentialism became popular in the 1960s when Jean-Paul Sartre was at the peak of his career, but after the 1980s, the philosophers started ignoring Sartre and that pushed Existentialism into oblivion.
