THREE:It remains to be seen whether the system which we are examining is consistent with itself. It is not. The Prime Mover, being unextended, cannot be located outside the sidereal sphere; nor can he be brought into immediate contact with it more than with any other part of the cosmos. If the aether has a motion proper to itself, then no spiritual agency is required to keep it in perpetual rotation. If the crystalline spheres fit accurately together, as they must, to avoid leaving a vacuum anywhere, there can be no friction, no production of heat, and consequently no effect produced on the sublunary sphere. Finally, no rotatory or other movement can, taken alone, have any conceivable connexion with the realisation of a possibility, in the sense of progress from a lower to a higher state of being. It is merely the perpetual exchange of one indifferent position for another.We must add, that while Epicurus was right in regarding the beliefs entertained about a future life as a source of painful anxiety, he was only justified in this opinion by the deeper truth, which he ignored, that they are simply the natural dread of death under another form.178 The most appalling pictures of damnation would, taken by themselves, probably add but little to human misery. The alarming effect even of earthly punishments is found to depend on their certainty much more93 than on their severity; and the certainty of suffering what nobody has ever experienced must be small indeed. Besides, the class most interested in enlarging on the dark side of immortality are also interested in showing that its dangers may be bought off at a comparatively trifling cost. What Epicurus said about the inexorable fate of the physicists might here be turned against himself. He removed terrors which there was a possibility of exorcising, and substituted a prospect of annihilation whence there was no escape.179
But I must explain to you how all this mistaken idea of denouncing pleasure and praising pain was born and I will give you a complete account of the system, and expound the actual teachings of the great
