But if I live in a world of nonabsolutes and would fight social injustice on the mood of the moment, how can I establish what social justice is? What criterion do I have to distinguish between right and wrong so that I can know what I should be fighting? Is it not possible that I could in fact acquiesce in evil and stamp out good? The word love cannot tell me how to discern, for within the humanistic framework love can have no defined meaning.
