Concerning the methods which nature hath afforded for computing time and space.
I Introduce here the subject proposed, because it affords several curious examples of the power of passion to adjust objects to its gratification; a lesson that cannot be too much inculcated, as there is not perhaps another bias in human nature that hath an influence so universal, and that is so apt to make us wander from truth as well as from justice.
I begin with time; and the question shortly is, What was the measure of time before artificial measures were invented? and, What is the measure at present when these are not at hand? I speak not of months and days, which we compute by the moon and sun; but of hours, or in general of the time that runs betwixt any two occurrences when there is not access to the sun. The only natural measure we have, is the train of our thoughts; and we always judge the time to be long or short, in proportion to the number of perceptions that have passed through the mind during that interval. This is indeed a very imperfect measure; because in the different conditions of a quick or slow succession, the computation is different. But however imperfect, it is the only measure by which a person naturally calculates time; and this measure is applied on all occasions, without regard to any occasional variation in the rate of succession.
This natural measure of time, imperfect as it is, would however be tolerable, did it labour under no other imperfection than the ordinary variations that happen in the motion of our perceptions. But in many particular circumstances, it is much more fallacious; and in order to explain these distinctly, I must analize the subject. Time is generally computed at two different periods; one while time is passing, another after it is past. I shall consider these separately, with the errors to which each of them is liable. It will be found that these errors often produce very different computations of the same period of time. The computation of time while it is passing, comes first in order. It is a common and trite observation, That to lovers absence appears immeasurably long, every minute an hour, and every hour a day. The same computation is made in every case where we long for a distant event; as where one is in expectation of good news, or where a profligate heir watches for the death of an old man who keeps him from a great estate. Opposite to these are instances not fewer in number. To a criminal the interval betwixt sentence and execution appears miserably short; and the same holds in every case where one dreads an approaching event. Of this even a schoolboy can bear witness: the hour allowed him for play, moves, in his apprehension, with a very swift pace: before he is thoroughly engaged, the hour is gone. A reckoning founded on the number of ideas, will never produce computations so regularly opposite to each other; for a slow succession of ideas is not connected with our wishes, nor a quick succession with our fears. What is it then, that, in the cases mentioned, moves nature to desert her common measure for one very different? I know not that this question ever has been resolved. The false reckonings I have suggested are so common and familiar, that no writer has thought of inquiring for their cause. And indeed, to enter upon this matter at short hand, without preparation, might occasion some difficulty. But to encounter the difficulty, we luckily are prepared by what is said above about the power of passion to fit objects for its gratification. Among the other circumstances that terrify a condemned criminal, the short time he has to live is one. Terror, like our other passions, prone to its gratification, adjusts every one of these circumstances to its own tone. It magnifies in particular the shortness of the interval betwixt the present time and that of the execution; and forces upon the criminal a conviction that the hour of his death approaches with a swift pace. In the same manner, among the other distresses of an absent lover, the time of separation is a capital circumstance, which for that reason is greatly magnified by his anxiety and impatience. He imagines that the time of meeting comes on very slow, or rather that it will never come. Every minute is thought of an intolerable length. Here is a fair and I hope satisfactory account, why we reckon time to be tedious when we long for a future event, and not less fleet when we dread the event. This account is confirmed by other instances. Bodily pain fixt to one part, produceth a slow train of perceptions, which, according to the common measure of time, ought to make it appear short. Yet we know, that in such a state time has the opposite appearance. Bodily pain is always attended with a degree of impatience and an anxiety to be rid of it, which make us judge every minute to be an hour. The same holds where the pain shifts from place to place; but not so remarkably, because such a pain is not attended with the same degree of impatience. The impatience a man hath in travelling through a barren country or in bad roads, makes him imagine, during the journey, that time goes on with a very slow pace. We shall show afterward that he makes a very different computation when his journey is at an end.
How ought it to stand with a man who apprehends bad news? It will probably be thought, that the case of this man resembles that of a criminal, who, in reckoning the short time he has to live, imagines every hour to be but a minute, and that time flies swift away. Yet the computation here is directly opposite. Reflecting upon this difficulty, there appears one capital circumstance in which the two cases differ. The fate of the criminal is determined: in the case under consideration, the man is still in suspense. Every one knows how distressful suspense is to the bulk of mankind. Such distress we wish to get rid of at any rate, even at the expence of bad news. This case therefore, upon a more narrow inspection, resembles that of bodily pain. The present distress in both cases, makes the time appear extremely tedious.
The reader probably will not be displeased, to have this branch of the subject illustrated in a pleasant manner, by an author acquainted with every maze of the human heart, and who bestows ineffable grace and ornament upon every subject he handles.
Rosalinda. I pray you, what is’t a clock?
Orlando. You should ask me, what time o’ day; there’s no clock in the forest.
Ros. Then there is no true lover in the forest; else, sighing every minute, and groaning every hour, would detect the lazy foot of Time, as well as a clock.
Orla. Why not the swift foot of Time? Had not that been as proper?
