ONE:To classify further��cutting machines may be divided into those wherein the tools move and the material is fixed, and those wherein the material is moved and the tools fixed, and machines which involve a compound movement of both the tools and the material acted upon.It had been urged against hedonism that pleasure is a process, a movement; whereas the supreme good must be a completed product��an end in which we can rest. Against sensual enjoyments in particular, it had been urged that they are caused by the satisfaction of appetite, and, as such, must result in a mere negative condition, marking the zero point of pleasurable sentiency. Finally, much stress had been laid on the anti-social and suicidal consequences of that selfish grasping at power to which habits of unlimited self-indulgence must infallibly lead. The form given to hedonism by Epicurus is a reaction against these criticisms, a modification imposed on it for the purpose of evading their force. He seems to admit that bodily satisfaction is rather the removal of a want, and consequently of a pain, than a source of positive pleasure. But the resulting condition of liberation from uneasiness is, according to him, all that we can desire; and by extending the same principle to every other good, he indirectly brings back the mental felicity which at first sight his system threatened either to exclude or to reduce to a mere shadow of sensual enjoyment. For, in calculating the elements of unhappiness, we have to deal, not only with present discomfort, but also, and to a far greater extent, with the apprehension of future evil. We dread the loss of worldly goods, of friends, of reputation, of life itself. We are continually exposed to pain, both from violence and from disease. We are haunted by visions of divine vengeance, both here and hereafter. To get rid of all such terrors, to possess our souls in peace, is the highest good��a permanent, as distinguished from a transient state of consciousness��and the proper business of philosophy is to show us how that consummation may be attained.65 Thus we are brought back to that blissful self-contemplation of mind which Aristotle had already declared to be the goal of all endeavour and the sole happiness of God.
