Life is certain to the will, and the present is certain to life. Time is like a perpetually revolving globe. The hemisphere which is sinking is like the past, that which is rising is like the future, while the indivisible point at the top is like the actionless present. Or, time is like a running river and the present is a rock on which it breaks but which it cannot remove with itself. Therefore we are not concerned to investigate the past antecedent to life, nor to speculate on the future subsequent to death. We should simply seek to know the present, that being the sole form in which the will manifests itself. Therefore, if we are satisfied with life as it is, we may confidently regard it as endless and banish the fear of death as illusive. Our spirit is of a totally indestructible nature, and its energy endures from eternity to eternity. It is like the sun, which seems to set only to our earthly eyes, but which, in reality, never sets, but shines on unceasingly. The problem of the freedom of the will is solved by the considerations which have been thus outlined. Since the will is not phenomenon, is not idea or object, but thing-in-itself, is not determined as a consequent through any reason, and knows no necessity, therefore it is _free_. But the person is never free, although he is the phenomenon of a free will, for this indisputable reason, that he is already the determined phenomenon of the free volition of this will, and is constrained to embody the direction of that volition in a multiplicity of actions. Repentance never results from a change of will, for this is impossible, but from a change of knowledge. The essential in what I have willed I must continue to will, for I am identical with this will which lies outside time and change. Therefore I cannot repent of what I have willed, though I can repent of what I have done; because, constrained by false notions, I was led to do what did not accord with my will. Repentance is simply the discovery of this fuller and more correct knowledge. SENECA On Benefits
