The brute is much more content with mere existence than man; the plant is wholly so; and man finds satisfaction in it just in proportion as he is dull and obtuse. Accordingly, the life of the brute carries less of sorrow with it, but also less of joy, when compared with the life of man; and while this may be traced, on the one side, to freedom from the torment of care and anxiety, it is also due to the fact that hope, in any real sense, is unknown to the brute. It is thus deprived of any share in that which gives us the most and best of our joys and pleasures, the mental anticipation of a happy future, and the inspiriting play of phantasy, both of which we owe to our power of imagination. If the brute is free from care, it is also, in this sense, without hope; in either case, because its consciousness is limited to the present moment, to what it can actually see before it. The brute is an embodiment of present impulses, and hence what elements of fear and hope exist in its nature—and they do not go very far—arise only in relation to objects that lie before it and within reach of those impulses: whereas a man’s range of vision embraces the whole of his life, and extends far into the past and future.
