The most famous book that talks to us of precisely “human” happiness, the proper happiness of man in so far as he is man in this world, is, no doubt, Aristotle’s Ethics. Here he tells us, as if looking into our own souls in our own time, that everything we do, all the particular, singular things in which our actions exist and which constitute the outlines of our lives, we do because we seek to be happy by the doing of these actions. This seeking to be happy in each particular act is what unites all the things that do exist in so far as they are touched by human minds and hands. All human beings reveal the same curious variety of longings in their origins. The world, in other words, is full of things that came to be because someone sought to be happy and did something to attain this purpose, albeit not always the right thing or the best thing..
Aristotle next explains to us that we can have differing ideas of that in which this happiness consists, but even here, the general diversity is not so great when we come to examine it. The great variations that seem at first sight evident in human searchings can be subsumed under four general headings. Some think that happiness is money, some pleasure, some honour or power, and still others think it consists in human contemplation of truth, of knowing the things that are. Happiness, Aristotle tells us; is an activity, it is an activity of our highest faculties on the highest objects
