There can be no advice where man has no power to choose his course of behavior.
Man is not fully conditioned and determined but rather determines himself whether he gives in to conditions or stands up to them. In other words, man is ultimately self-determining. Man does not simply exist but always decides what his existence will be, what he will become in the next moment.
To be sure, a human being is a finite thing, and his freedom is restricted. It is not freedom from conditions, but it is freedom to take a stand toward the conditions.
