SECTION 49. That Time works great changes, and that all things are
in their nature fleeting—these are truths that should never be forgotten. Hence, in whatever case you may be, it is well to picture to yourself the opposite: in prosperity, to be mindful of misfortune; in friendship, of enmity; in good weather, of days when the sky is overcast; in love, of hatred; in moments of trust, to imagine the betrayal that will make you regret your confidence; and so, too, when you are in evil plight, to have a lively sense of happier times—what a lasting source of true worldly wisdom were there! We should then always reflect, and not be so very easily deceived; because, in general, we should anticipate the very changes that the years will bring.
Perhaps in no form of knowledge is personal experience so indispensable as in learning to see that all things are unstable and transitory in this world. There is nothing that, in its own place and for the time it lasts, is not a product of necessity, and therefore capable of being fully justified; and it is this fact that makes circumstances of every year, every month, even of every day, seem as though they might maintain their right to last to all eternity. But we know that this can never be the case, and that in a world where all is fleeting, change alone endures. He is a prudent man who is not only undeceived by apparent stability, but is able to forecast the lines upon which movement will take place.[47]

[ Chance plays so great a part in all human affairs that when a man tries to ward off a remote danger by present sacrifice, the danger often vanishes under some new and unforeseen development of events; and then the sacrifice, in addition to being a complete loss, brings about such an altered state of things as to be in itself a source of positive danger in the face of this new development. In taking measures of precaution, then, it is well not to look too far ahead, but to reckon with chance; and often to oppose a courageous front to a danger, in the hope that, like many a dark thunder-cloud, it may pass away without breaking.]
But people generally think that present circumstances will last, and that matters will go on in the future as they have clone in the past. Their mistakes arises from the fact that they do not understand the cause of the things they see—causes which, unlike the effects they produce, contain in themselves the germ of future change. The effects are all that people know, and they hold fast to them on the supposition that those unknown causes, which were sufficient to bring them about, will also be able to maintain them as they are. This is a very common error; and the fact that it is common is not without its advantage, for it means that people always err in unison; and hence the calamity which results from the error affects all alike, and is therefore easy to bear; whereas, if a philosopher makes a mistake, he is alone in his error, and so at a double disadvantage.[48]

[ I may remark, parenthetically, that all this is a confirmation of the principle laid down in Die Welt als Wille und Vorstellung (Bk. I. p. 94: 4th edit.), that error always consists in making a wrong inference, that is, in ascribing a given effect to something that did not cause it.]
But in saying that we should anticipate the effects of time, I mean that we should mentally forecast what they are likely to be; I do not mean that we should practically forestall them, by demanding the immediate performance of promises which time alone can fulfill. The man who makes his demand will find out that there is no worse or more exacting usurer than Time; and that, if you compel Time to give money in advance, you will have to pay a rate of interest more ruinous than any Jew would require. It is possible, for instance, to make a tree burst forth into leaf, blossom, or even bear fruit within a few days, by the application of unslaked lime and artificial heat; but after that the tree will wither away. So a young man may abuse his strength—it may be only for a few weeks—by trying to do at nineteen what he could easily manage at thirty, and Time may give him the loan for which he asks; but the interest he will have to pay comes out of the strength of his later years; nay, it is part of his very life itself.
There are some kinds of illness in which entire restoration to health is possible only by letting the complaint run its natural course; after which it disappears without leaving any trace of its existence. But if the sufferer is very impatient, and, while he is still affected, insists that he is completely well, in this case, too, Time will grant the loan, and the complaint may be shaken off; but life-long weakness and chronic mischief will be the interest paid upon it.
Again, in time of war or general disturbance, a man may require ready money at once, and have to sell out his investments in land or consols for a third or even a still smaller fraction of the sum he would have received from them, if he could have waited for the market to right itself, which would have happened in due course; but he compels Time to grant him a loan, and his loss is the interest he has to pay. Or perhaps he wants to go on a long journey and requires the money: in one or two years he could lay by a sufficient sum out of his income, but he cannot afford to wait; and so he either borrows it or deducts it from his capital; in other words, he gets Time to lend him the money in advance. The interest he pays is a disordered state of his accounts, and permanent and increasing deficits, which he can never make good.
Such is Time's usury; and all who cannot wait are its victims. There is no more thriftless proceeding than to try and mend the measured pace of Time. Be careful, then, not to become its debtor.
