Basically, there are three schools of thought regarding human moral responsibility. First, there is nihilism. Nihilism argues that there is no God, hence anything one wishes to do is permitted. Second, there is relativism.
Relativism contends that all conduct is relative to the circumstance.
Thus, each individual must decide what is moral or immoral in a given situation. Ultimately, every man is his own judge of the matter. Third, there is absolutism. There are two fundamental categories of situation ethicists. The foregoing declaration is wholly void of reason.
