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. The tiler on the roof does not know what it is to be dizzy, and those who are used to the dark will not be afraid.

There is another advantage to be gained from our games in the dark. But if these games are to be a success I cannot speak too strongly of the need for gaiety. Nothing is so gloomy as the dark: do not shut your child up in a dungeon, let him laugh when he goes, into a dark place, let him laugh when he comes out, so that the thought of the game he is leaving and the games he will play next may protect him from the fantastic imagination which might lay hold on him.

There comes a stage in life beyond which we progress backwards. I feel I have reached this stage. I am, so to speak, returning to a past career. The approach of age makes us recall the happy days of our childhood. As I grow old I become a child again, and I recall more readily what I did at ten than at thirty. Reader, forgive me if I sometimes draw my examples from my own experience. If this book is to be well written, I must enjoy writing it.

I was living in the country with a pastor called M. Lambercier. My companion was a cousin richer than myself, who was regarded as the heir to some property, while I, far from my father, was but a poor orphan. My big cousin Bernard was unusually timid, especially at night. I laughed at his fears, till M. Lambercier was tired of my boasting, and determined to put my courage to the proof. One autumn evening, when it was very dark, he gave me the church key, and told me to go and fetch a Bible he had left in the pulpit. To put me on my mettle he said something which made it impossible for me to refuse.

I set out without a light; if I had had one, it would perhaps have been even worse. I had to pass through the graveyard; I crossed it bravely, for as long as I was in the open air I was never afraid of the dark.

As I opened the door I heard a sort of echo in the roof; it sounded like voices and it began to shake my Roman courage. Having opened the door I tried to enter, but when I had gone a few steps I stopped. At the sight of the profound darkness in which the vast building lay I was seized with terror and my hair stood on end. I turned, I went out through the door, and took to my heels. In the yard I found a little dog, called Sultan, whose caresses reassured me. Ashamed of my fears, I retraced my steps, trying to take Sultan with me, but he refused to follow. Hurriedly I opened the door and entered the church. I was hardly inside when terror again got hold of me and so firmly that I lost my head, and though the pulpit was on the right, as I very well knew, I sought it on the left, and entangling myself among the benches I was completely lost. Unable to find either pulpit or door, I fell into an indescribable state of mind. At last I found the door and managed to get out of the church and run away as I had done before, quite determined never to enter the church again except in broad daylight.

I returned to the house; on the doorstep I heard M. Lambercier laughing, laughing, as I supposed, at me. Ashamed to face his laughter, I was hesitating to open the door, when I heard Miss Lambercier, who was anxious about me, tell the maid to get the lantern, and M. Lambercier got ready to come and look for me, escorted by my gallant cousin, who would have got all the credit for the expedition. All at once my fears departed, and left me merely surprised at my terror. I ran, I fairly flew, to the church; without losing my way, without groping about, I reached the pulpit, took the Bible, and ran down the steps. In three strides I was out of the church, leaving the door open. Breathless, I entered the room and threw the Bible on the table, frightened indeed, but throbbing with pride that I had done it without the proposed assistance.

You will ask if I am giving this anecdote as an example, and as an illustration, of the mirth which I say should accompany these games. Not so, but I give it as a proof that there is nothing so well calculated to reassure any one who is afraid in the dark as to hear sounds of laughter and talking in an adjoining room. Instead of playing alone with your pupil in the evening, I would have you get together a number of merry children; do not send them alone to begin with, but several together, and do not venture to send any one quite alone, until you are quite certain beforehand that he will not be too frightened.

I can picture nothing more amusing and more profitable than such games, considering how little skill is required to organise them. In a large room I should arrange a sort of labyrinth of tables, armchairs, chairs, and screens. In the inextricable windings of this labyrinth I should place some eight or ten sham boxes, and one real box almost exactly like them, but well filled with sweets. I should describe clearly and briefly the place where the right box would be found. I should give instructions sufficient to enable people more attentive and less excitable than children to find it. [Footnote: To practise them in attention, only tell them things which it is clearly to their present interest that they should understand thoroughly; above all be brief, never say a word more than necessary. But neither let your speech be obscure nor of doubtful meaning.] Then having made the little competitors draw lots, I should send first one and then another till the right box was found. I should increase the difficulty of the task in proportion to their skill.

Picture to yourself a youthful Hercules returning, box in hand, quite proud of his expedition. The box is placed on the table and opened with great ceremony. I can hear the bursts of laughter and the shouts of the merry party when, instead of the looked-for sweets, he finds, neatly arranged on moss or cotton-wool, a beetle, a snail, a bit of coal, a few acorns, a turnip, or some such thing. Another time in a newly whitewashed room, a toy or some small article of furniture would be hung on the wall and the children would have to fetch it without touching the wall. When the child who fetches it comes back, if he has failed ever so little to fulfil the conditions, a dab of white on the brim of his cap, the tip of his shoe, the flap of his coat or his sleeve, will betray his lack of skill.

This is enough, or more than enough, to show the spirit of these games. Do not read my book if you expect me to tell you everything.

What great advantages would be possessed by a man so educated, when compared with others. His feet are accustomed to tread firmly in the dark, and his hands to touch lightly; they will guide him safely in the thickest darkness. His imagination is busy with the evening games of his childhood, and will find it difficult to turn towards objects of alarm. If he thinks he hears laughter, it will be the laughter of his former playfellows, not of frenzied spirits; if he thinks there is a host of people, it will not be the witches' sabbath, but the party in his tutor's study. Night only recalls these cheerful memories, and it will never alarm him; it will inspire delight rather than fear. He will be ready for a military expedition at any hour, with or without his troop. He will enter the camp of Saul, he will find his way, he will reach the king's tent without waking any one, and he will return unobserved. Are the steeds of Rhesus to be stolen, you may trust him. You will scarcely find a Ulysses among men educated in any other fashion.

I have known people who tried to train the children not to fear the dark by startling them. This is a very bad plan; its effects are just the opposite of those desired, and it only makes children more timid. Neither reason nor habit can secure us from the fear of a present danger whose degree and kind are unknown, nor from the fear of surprises which we have often experienced. Yet how will you make sure that you can preserve your pupil from such accidents? I consider this the best advice to give him beforehand. I should say to Emile, "This is a matter of self-defence, for the aggressor does not let you know whether he means to hurt or frighten you, and as the advantage is on his side you cannot even take refuge in flight. Therefore seize boldly anything, whether man or beast, which takes you unawares in the dark. Grasp it, squeeze it with all your might; if it struggles, strike, and do not spare your blows; and whatever he may say or do, do not let him go till you know just who he is. The event will probably prove that you had little to be afraid of, but this way of treating practical jokers would naturally prevent their trying it again."

Although touch is the sense oftenest used, its discrimination remains, as I have already pointed out, coarser and more imperfect than that of any other sense, because we always use sight along with it; the eye perceives the thing first, and the mind almost always judges without the hand. On the other hand, discrimination by touch is the surest just because of its limitations; for extending only as far as our hands can reach, it corrects the hasty judgments of the other senses, which pounce upon objects scarcely perceived, while what we learn by touch is learnt thoroughly. Moreover, touch, when required, unites the force of our muscles to the action of the nerves; we associate by simultaneous sensations our ideas of temperature, size, and shape, to those of weight and density. Thus touch is the sense which best teaches us the action of foreign bodies upon ourselves, the sense which most directly supplies us with the knowledge required for self-preservation.

As the trained touch takes the place of sight, why should it not, to some extent, take the place of hearing, since sounds set up, in sonorous bodies, vibrations perceptible by touch? By placing the hand on the body of a 'cello one can distinguish without the use of eye or ear, merely by the way in which the wood vibrates and trembles, whether the sound given out is sharp or flat, whether it is drawn from the treble string or the bass. If our touch were trained to note these differences, no doubt we might in time become so sensitive as to hear a whole tune by means of our fingers. But if we admit this, it is clear that one could easily speak to the deaf by means of music; for tone and measure are no less capable of regular combination than voice and articulation, so that they might be used as the elements of speech.

There are exercises by which the sense of touch is blunted and deadened, and others which sharpen it and make it delicate and discriminating. The former, which employ much movement and force for the continued impression of hard bodies, make the skin hard and thick, and deprive it of its natural sensitiveness. The latter are those which give variety to this feeling, by slight and repeated contact, so that the mind is attentive to constantly recurring impressions, and readily learns to discern their variations. This difference is clear in the use of musical instruments. The harsh and painful touch of the 'cello, bass-viol, and even of the violin, hardens the finger-tips, although it gives flexibility to the fingers. The soft and smooth touch of the harpsichord makes the fingers both flexible and sensitive. In this respect the harpsichord is to be preferred.

The skin protects the rest of the body, so it is very important to harden it to the effects of the air that it may be able to bear its changes. With regard to this I may say I would not have the hand roughened by too servile application to the same kind of work, nor should the skin of the hand become hardened so as to lose its delicate sense of touch which keeps the body informed of what is going on, and by the kind of contact sometimes makes us shudder in different ways even in the dark.

Why should my pupil be always compelled to wear the skin of an ox under his foot? What harm would come of it if his own skin could serve him at need as a sole. It is clear that a delicate skin could never be of any use in this way, and may often do harm. The Genevese, aroused at midnight by their enemies in the depth of winter, seized their guns rather than their shoes. Who can tell whether the town would have escaped capture if its citizens had not been able to go barefoot?
