I do not care to multiply the material for these collections of maxims. I shall only add one last and solemn truth. It is this,--that under the conditions of human life unhappiness also is necessary. Indeed, if one cared to state it in a paradox, he might say that unhappiness is essential to happiness. In the first place, as the experience of life plainly shows, unhappiness is inevitable, and one must in one way or another reconcile himself to it. The most to which one can attain in this human lot is perfect adjustment to one’s destiny; that inward and permanent peace which, as Isaiah says, is like an “overflowing stream.” It is this peace and this alone which Christ promises to his disciples, and it is this, and no outward satisfaction, which the Apostle Paul expects for his fellow-Christians, when, at the end of his unpeaceful life, he prays that “the peace of Christ may rule” in their hearts. Thus, for real happiness the outward issue of events may come to have no high importance. Stoicism endeavored to solve the problem of happiness by developing insensibility to pain, but its endeavor was vain. The problem of happiness is to be solved in quite another way. One must accept his suffering and unhappiness, and adjust himself to them. And to this end one is, first of all, helped by considering what unhappiness implies, and by living consistently above the sway of momentary feeling. For unhappiness does us good in no less than three ways,--ways which are cumulative in their effect. It is, in the first place, a punishment, the natural consequence of our deeds. It is, thus considered, a part of those deeds themselves, and therefore must follow them as surely as a logical consequence follows its premise. Unhappiness is, secondly, a cleansing process, waking us to greater seriousness and greater receptivity to truth. Thirdly, unhappiness recalls us to self-examination and fortifies us by disclosing what is our own strength, and what is God’s strength. By no other experience does one attain that spiritual courage which is far removed from self-confidence and very near to humility. In a word, it must be said that the deeper life of man and that noble bearing which we remark in some people, and which no one, whatever be his station, can falsely assume, are attained only through faithful endurance of misfortune. That word of the Apostle Paul, “We glory in tribulations,” is, like many of his sayings, absolutely unintelligible to any one who has not experienced what renewal of power and what profound happiness may be discovered through misfortune itself. It is a form of happiness which one never forgets if he has once really experienced it. This, then, is the riddle of life which perplexes many a man and turns him from the right way,--that good people do not get the good things which might seem to them their due.
