Emile by Jean-Jacques Rousseau (most read book in the world TXT) 📕

A child is smaller than a man; he has not the man’s strength or reason, but he sees and hears as well or nearly as well; his sense of taste is very good, though he is less fastidious, and he distinguishes scents as clearly though less sensuously. The senses are the first of our faculties to mature; they are those most frequently overlooked or neglected.

To train the senses it is not enough merely to use them; we must learn to judge by their means, to learn to feel, so to speak; for we cannot touch, see, or hear, except as we have been taught.

There is a mere natural and mechanical use of the senses which strengthens the body without improving the judgment. It is all very well to swim, run, jump, whip a top, throw stones; but have we nothing but arms and legs? Have we not eyes and ears as well; and are not these organs necessary for the use of the rest? Do not merely exercise the strength, exercise all the senses by which it is guided; make the best use of every one of them, and check the results of one by the other. Measure, count, weigh, compare. Do not use force till you have estimated the resistance; let the estimation of the effect always precede the application of the means. Get the child interested in avoiding insufficient or superfluous efforts.

If in this way you train him to calculate the effects of all his movements, and to correct his mistakes by experience, is it not clear that the more he does the wiser he will become?

Take the case of moving a heavy mass; if he takes too long a lever, he will waste his strength; if it is too short, he will not have strength enough; experience will teach him to use the very stick he needs. This knowledge is not beyond his years. Take, for example, a load to be carried; if he wants to carry as much as he can, and not to take up more than he can carry, must he not calculate the weight by the appearance? Does he know how to compare masses of like substance and different size, or to choose between masses of the same size and different substances? He must set to work to compare their specific weights. I have seen a young man, very highly educated, who could not be convinced, till he had tried it, that a bucket full of blocks of oak weighed less than the same bucket full of water.

All our senses are not equally under our control. One of them, touch, is always busy during our waking hours; it is spread over the whole surface of the body, like a sentinel ever on the watch to warn us of anything which may do us harm. Whether we will or not, we learn to use it first of all by experience, by constant practice, and therefore we have less need for special training for it. Yet we know that the blind have a surer and more delicate sense of touch than we, for not being guided by the one sense, they are forced to get from the touch what we get from sight. Why, then, are not we trained to walk as they do in the dark, to recognise what we touch, to distinguish things about us; in a word, to do at night and in the dark what they do in the daytime without sight? We are better off than they while the sun shines; in the dark it is their turn to be our guide. We are blind half our time, with this difference: the really blind always know what to do, while we are afraid to stir in the dark. We have lights, you say. What always artificial aids. Who can insure that they will always be at hand when required.

I had rather Emil’s eyes were in his finger tips, than in the chandler’s shop.

If you are shut up in a building at night, clap your hands, you will know from the sound whether the space is large or small, if you are in the middle or in one corner. Half a foot from a wall the air, which is refracted and does not circulate freely, produces a different effect on your face. Stand still in one place and turn this way and that; a slight draught will tell you if there is a door open. If you are on a boat you will perceive from the way the air strikes your face not merely the direction in which you are going, but whether the current is bearing you slow or fast. These observations and many others like them can only be properly made at night; however much attention we give to them by daylight, we are always helped or hindered by sight, so that the results escape us. Yet here we use neither hand nor stick. How much may be learnt by touch, without ever touching anything!

I would have plenty of games in the dark! This suggestion is more valuable than it seems at first sight. Men are naturally afraid of the dark; so are some animals. [Footnote: This terror is very noticeable during great eclipses of the sun.] Only a few men are freed from this burden by knowledge, determination, and courage.

I have seen thinkers, unbelievers, philosophers, exceedingly brave by daylight, tremble like women at the rustling of a leaf in the dark. This terror is put down to nurses’ tales; this is a mistake; it has a natural cause. What is this cause? What makes the deaf suspicious and the lower classes superstitious? Ignorance of the things about us, and of what is taking place around us. [Footnote: Another cause has been well explained by a philosopher, often quoted in this work, a philosopher to whose wide views I am very greatly indebted.]

When under special conditions we cannot form a fair idea of distance, when we can only judge things by the size of the angle or rather of the image formed in our eyes, we cannot avoid being deceived as to the size of these objects. Every one knows by experience how when we are travelling at night we take a bush near at hand for a great tree at a distance, and vice versa. In the same way, if the objects were of a shape unknown to us, so that we could not tell their size in that way, we should be equally mistaken with regard to it. If a fly flew quickly past a few inches from our eyes, we should think it was a distant bird; a horse standing still at a distance from us in the midst of open country, in a position somewhat like that of a sheep, would be taken for a large sheep, so long as we did not perceive that it was a horse; but as soon as we recognise what it is, it seems as large as a horse, and we at once correct our former judgment.

Whenever one finds oneself in unknown places at night where we cannot judge of distance, and where we cannot recognise objects by their shape on account of the darkness, we are in constant danger of forming mistaken judgments as to the objects which present themselves to our notice. Hence that terror, that kind of inward fear experienced by most people on dark nights. This is foundation for the supposed appearances of spectres, or gigantic and terrible forms which so many people profess to have seen. They are generally told that they imagined these things, yet they may really have seen them, and it is quite possible they really saw what they say they did see; for it will always be the case that when we can only estimate the size of an object by the angle it forms in the eye, that object will swell and grow as we approach it; and if the spectator thought it several feet high when it was thirty or forty feet away, it will seem very large indeed when it is a few feet off; this must indeed astonish and alarm the spectator until he touches it and perceives what it is, for as soon as he perceives what it is, the object which seemed so gigantic will suddenly shrink and assume its real size, but if we run away or are afraid to approach, we shall certainly form no other idea of the thing than the image formed in the eye, and we shall have really seen a gigantic figure of alarming size and shape. There is, therefore, a natural ground for the tendency to see ghosts, and these appearances are not merely the creation of the imagination, as the men of science would have us think.—Buffon, Nat. Hist.

In the text I have tried to show that they are always partly the creation of the imagination, and with regard to the cause explained in this quotation, it is clear that the habit of walking by night should teach us to distinguish those appearances which similarity of form and diversity of distance lend to the objects seen in the dark. For if the air is light enough for us to see the outlines there must be more air between us and them when they are further off, so that we ought to see them less distinctly when further off, which should be enough, when we are used to it, to prevent the error described by M. Buffon. [Whichever explanation you prefer, my mode of procedure is still efficacious, and experience entirely confirms it.] Accustomed to perceive things from a distance and to calculate their effects, how can I help supposing, when I cannot see, that there are hosts of creatures and all sorts of movements all about me which may do me harm, and against which I cannot protect myself? In vain do I know I am safe where I am; I am never so sure of it as when I can actually see it, so that I have always a cause for fear which did not exist in broad daylight. I know, indeed, that a foreign body can scarcely act upon me without some slight sound, and how intently I listen! At the least sound which I cannot explain, the desire of self-preservation makes me picture everything that would put me on my guard, and therefore everything most calculated to alarm me.

I am just as uneasy if I hear no sound, for I might be taken unawares without a sound. I must picture things as they were before, as they ought to be; I must see what I do not see. Thus driven to exercise my imagination, it soon becomes my master, and what I did to reassure myself only alarms me more. I hear a noise, it is a robber; I hear nothing, it is a ghost. The watchfulness inspired by the instinct of self-preservation only makes me more afraid. Everything that ought to reassure me exists only for my reason, and the voice of instinct is louder than that of reason. What is the good of thinking there is nothing to be afraid of, since in that case there is nothing we can do?

The cause indicates the cure. In everything habit overpowers imagination; it is only aroused by what is new. It is no longer imagination, but memory which is concerned with what we see every day, and that is the reason of the maxim, “Ab assuetis non fit passio,” for it is only at the flame of imagination that the passions are kindled. Therefore do not argue with any one whom you want to cure of the fear of darkness; take him often into dark places and be assured this practice will be of more avail than all the arguments of philosophy.
