The universal survey of life as a whole, an advantage which man has over the animal through his faculty of reason, is also comparable to a geometrical, colourless, abstract, reduced plan of his way of life. He is therefore related to the animal as the navigator, who by means of chart, compass, and quadrant knows accurately at any moment his course and position on the sea, is related to the uneducated crew who see only the waves and skies. It is therefore worth noting, and indeed wonderful to see, how man, besides his life in the concrete, always lives a second life in the abstract. In the former he is abandoned to all the storms of reality and to the influence of the present; he must struggle, suffer, and die like the animal. But his life in the abstract, as it stands before his rational consciousness, is the calm reflection of his life in the concrete, and of the world in which he lives; it is precisely that reduced chart or plan previously mentioned. Here in the sphere of calm deliberation, what previously possessed him completely and moved him intensely appears to him cold, colourless, and, for the moment, foreign and strange; he is a mere spectator and observer. In respect of this withdrawal into reflection, he is like an actor who has played his part in one scene, and takes his place in the audience until he must appear again. In the audience he quietly looks on at whatever may happen, even though it be the preparation of his own death (in the play); but then he again goes on the stage, and acts and suffers as he must. From this double life proceeds that composure in man, so very different from the thoughtlessness of the animal. According to previous reflection, to a mind made up, or to a recognized necessity, a man with such composure suffers or carries out in cold blood what is of the greatest, and often most terrible, importance to him, such as suicide, execution, duels, hazardous enterprises of every kind fraught with danger to life, and generally things against which his whole animal nature rebels. We then see to what extent reason is master of the animal nature, and we exclaim to the strong: ferreum certe tibi cor! (Truly hast thou a heart of iron!) [Iliad, xxiv, 521.] Here it can really be said that the faculty of reason manifests itself practically, and thus practical reason shows itself, wherever action is guided by reason, where motives are abstract concepts, wherever the determining factors are not individual representations of perception, or the impression of the moment which guides the animal.
