把这一句，留给此刻的你
It has generally been assumed that of two opposing systems of philosophy, e.g., realism and idealism, one only can be true and one must be false; and so philosophers have been hopelessly divided on the question, which is the true one.
一般认为，在现实主义和唯心主义这两种对立的哲学体系中，只有一种是正确的，另一种必须是错误的;因此，哲学家们在这个问题上产生了无可救药的分歧，这个问题才是真正的问题。
