"Little inconveniences, exertions, pains.--these are the only things in which we rightly feel our life at all. If these be not there, existence becomes worthless, or worse; {102} success in putting them all away is fatal. So it is men engage in athletic sports, spend their holidays in climbing up mountains, find nothing so enjoyable as that which taxes their endurance and their energy. This is the way we are made, I say. It may or may not be a mystery or a paradox; it is a fact. Now, this enjoyment in endurance is just according to the intensity of life: the more physical vigor and balance, the more endurance can be made an element of satisfaction. A sick man cannot stand it. The line of enjoyable suffering is not a fixed one; it fluctuates with the perfectness of the life. That our pains are, as they are, unendurable, awful, overwhelming, crushing, not to be borne save in misery and dumb impatience, which utter exhaustion alone makes patient,--that our pains are thus unendurable, means not that they are too great, but that _we are sick_. We have not got our proper life. So you perceive pain is no more necessarily an evil, but an essential element of the highest good."[3] But the highest good can be achieved only by our getting our proper life; and that can come about only by help of a moral energy born of the faith that in some way or other we shall succeed in getting it if we try pertinaciously enough. This world _is_ good, we must say, since it is what we make it,--and we shall make it good. How can we exclude from the cognition of a truth a faith which is involved in the creation of the truth? _M_ has its character indeterminate, susceptible of forming part of a thorough-going pessimism on the one hand, or of a meliorism, a moral (as distinguished from a sensual) optimism on the other. All depends on the character of the {103} personal contribution _x_. Wherever the facts to be formulated contain such a contribution, we may logically, legitimately, and inexpugnably believe what we desire. The belief creates its verification. The thought becomes literally father to the fact, as the wish was father to the thought.[4]
