In the next place, many of the so-called evils of life do not involve any actual suffering. If for instance a man loses the sight of one eye, he need not have any pain; and were he originally blind the possession of even one eye would have been thought a priceless blessing. Again, however great may be the sufferings of life, they cannot be as great as its joys, since nearly everyone wishes to go on living. While it is undeniable that human pain, like that of animals, is most useful, serving to warn men of dangers and diseases, which would otherwise lead to their destruction.
Moreover, in a material world like ours, if the forces of nature act according to fixed laws, a certain amount of suffering seems inevitable. If, for example, the force of gravity always acts as it does, it will occasionally cause a tower to fall and injure someone. Such an event could only be avoided by God's continually interfering with these forces. But this would render all human life a hopeless confusion. While, at present, owing to these forces being invariable, a great deal of the evil which might otherwise result from them can be foreseen and avoided. If, however, men will not avoid it,—if, for instance, in spite of the numerous eruptions of Vesuvius, they still choose to go and live on its slopes,—it is hard to see how they can blame anyone but themselves. In the same way, if a man chooses to sit on the safety valve of an engine, it is his own fault if he gets blown up.
And even in other cases, when the evil cannot be foreseen, as in an unexpected earthquake, it is at least open to doubt whether it is any worse for a number of men to die like this, suddenly and together, than that they should all die in the usual way, slowly, one by one, and often after a long illness. It of course appeals more to the imagination, but it probably involves less suffering.
Thus we may say that human suffering, excluding that due to man himself, is by no means so great as it seems; that it is, as a rule, more than counter-balanced by human happiness; and that a certain amount seems not only useful, but in a world like ours inevitable. But though all these considerations are undoubtedly true, and undoubtedly lessen the difficulty, they do not remove it altogether.
The following appears to be the true explanation: that though God foreknew all this suffering when He created the world, and in this sense designed it, He need not have desired it, but may have desired something else, for the attainment of which, this suffering was a necessary condition. And this something else must obviously have been the training and perfecting of man's character; for which, some kind of suffering seems essential.
For if there were no suffering in the world, there could be no fortitude, no bravery, no patience, no compassion, no sympathy with others, no self-sacrifice for their good—nothing, in fact, that constitutes the highest type of man. In other words, a being such as man, can only be made perfect through suffering. Therefore this suffering implies no defect in God's design. It is a means, and, as far as we can judge, the only possible means for developing the highest and noblest character in man, such a character indeed as alone makes him worthy of admiration. Moreover, a man's character can only be formed by himself, it cannot be given him ready-made, for then it would not be his character at all; and it can only be formed gradually, it cannot be done all at once. Therefore, if God wishes a man to have the special character acquired by constantly bearing suffering, it can only be obtained by constantly giving him suffering to bear.
Here, then, we have the most probable explanation of the physical evils which man endures. Their object is to develop and perfect his character; and as this is a good object, and as it cannot be obtained in any other way, they may well have been designed by a good God.
(3.) Moral evil in man.
But we now come to the most difficult part of the subject, the existence of moral evil in man. This, as before said, is the chief cause of human misery, and might it not have been avoided? In other words, could not all sin have been excluded from the world? But assuming man to be a free being, it could not have been avoided, for freedom is always liable to abuse. Therefore, if God decided that man was to be free in some cases to act right or wrong, it necessarily follows that he may act wrong. No Omnipotence could possibly alter this without destroying man's freedom. Hence, though God designed all the moral evil in the world, He need not have desired it, but (as before) may have desired some totally different object, for the attainment of which, this evil was a necessary condition.
