VI] evil or ugly, which are purely imaginary, is essential to the Ideal. In this case the burden of proof lies the other way. It cannot be doubted that the appreciation of tragedy is a great positive good; and it seems almost equally certain that the virtues of compassion, courage, and self-control contain such goods. And to all these the cognition of things which would be evil, if they existed, is analytically necessary. Here then we have things of which the existence must add value to any whole in which they are contained; nor is it possible to assure ourselves that any whole, from which they were omitted, would thereby gain more in its value as a whole, than it would lose by their omission. We have no reason to think that any whole, which did not contain them, would be so good on the whole as some whole in which they were obtained. The case for their inclusion in the Ideal is as strong as that for the inclusion of material qualities (§ 123, above). Against the inclusion of these goods nothing can be urged except a bare possibility.

Finally (3) it is important to insist that, as was said above, these mixed virtues have a great practical value, in addition to that which they possess either in themselves or as mere means. Where evils do exist, as in this world they do, the fact that they are known and properly appreciated, constitutes a state of things having greater value as a whole even than the same appreciation of purely imaginary evils. This state of things, it has been said, is never positively good on the whole; but where the evil, which reduces its total value to a negative quantity, already unavoidably exists, to obtain the intrinsic value which belongs to it as a whole will obviously produce a better state of affairs than if the evil had existed by itself, quite apart from the good element in it which is identical with the appreciation of imaginary evils, and from any ulterior consequences which its existence may bring about. The case is here the same as with retributive punishment. Where an evil already exists, it is well that it should be pitied or hated or endured, according to its nature; just as it may be well that some evils should be punished. Of course, as in all practical cases, it often happens that the attainment of this good is incompatible with the attainment of another and a greater one. But it is important
