2. Contentment is not happiness. A man is content with little, but it takes an immensity of good to satisfy all his desire, and render him perfectly happy. When we say we are content, we signify that we should naturally desire more, but acquiesce in our present portion, seeing that more is not to be had. "Content," says Dr. Bain, "is not the natural frame of any mind, but is the result of compromise." 3. But is not this desire of unmixed happiness unreasonable? Are we not taught to set bounds to our desire? Is not moderation a virtue, and contentment wisdom? Yes, moderation is a virtue, but it concerns only the use of means, not the apprehension of ends. The patient, not to say the physician, desires medicines in moderation, so much as will do him good and no more; but, so far as his end is health, he desires all possible health, perfect health. The last end, then, is to be desired as a thing to possess without end or measure, fully and without defect. 4. We have then these facts to philosophise on: that all men desire perfect happiness: that this desire is natural, springing from the rational soul which sets man above the brute: that on earth man may attain to contentment, and to some happiness, but not to perfect happiness: that consequently nature has planted in man a desire for which on earth she has provided no adequate satisfaction. 5. If the course of events were fitful and wayward, so that effects started up without causes, and like causes under like conditions produced unlike effects, and anything might come of anything, there would be no such thing as that which we call _nature_. When we speak of nature, we imply a regular and definite flow of tendencies, this thing springing from that and leading to that other; nothing from nothing, and nothing leading nowhere; no random, aimless proceedings; but definite results led up to by a regular succession of steps, and surely ensuing unless something occurs on the way to thwart the process. How this is reconciled with Creation and Freewill, it is not our province to enquire: suffice it to say that a _natural_ agent is opposed to a _free_ one, and creation is the starting-point of nature. But to return. Everywhere we say, "this is for that," wherever there appears an end and consummation to which the process leads, provided it go on unimpeded. Now every event that happens is a part of some process or other. Every act is part of a tendency. There are no loose facts in nature, no things that happen, or are, otherwise than in consequence of something that has happened, or been, before, and in view of something else that is to happen, or be, hereafter. The tendencies of nature often run counter to one another, so that the result to which this or that was tending is frustrated. But a tendency is a tendency, although defeated; _this_ was for _that_, although that for which it was has got perverted to something else. There is no tendency which of itself fails and comes to naught, apart from
