teach children these virtues by name alone; they must learn them unconsciously through experience.
But speaking of death, what steps shall I take with regard to my pupil and the smallpox? Shall he be inoculated in infancy, or shall I wait till he takes it in the natural course of things? The former plan is more in accordance with our practice, for it preserves his life at a time when it is of greater value, at the cost of some danger when his life is of less worth; if indeed we can use the word danger with regard to inoculation when properly performed.
But the other plan is more in accordance with our general principles—to leave nature to take the precautions she delights in, precautions she abandons whenever man interferes. The natural man is always ready; let nature inoculate him herself, she will choose the fitting occasion better than we.
Do not think I am finding fault with inoculation, for my reasons for exempting my pupil from it do not in the least apply to yours. Your training does not prepare them to escape catching smallpox as soon as they are exposed to infection. If you let them take it anyhow, they will probably die. I perceive that in different lands the resistance to inoculation is in proportion to the need for it; and the reason is plain. So I scarcely condescend to discuss this question with regard to Emile. He will be inoculated or not according to time, place, and circumstances; it is almost a matter of indifference, as far as he is concerned. If it gives him smallpox, there will be the advantage of knowing what to expect, knowing what the disease is; that is a good thing, but if he catches it naturally it will have kept him out of the doctor's hands, which is better.
An exclusive education, which merely tends to keep those who have received it apart from the mass of mankind, always selects such teaching as is costly rather than cheap, even when the latter is of more use. Thus all carefully educated young men learn to ride, because it is costly, but scarcely any of them learn to swim, as it costs nothing, and an artisan can swim as well as any one. Yet without passing through the riding school, the traveller learns to mount his horse, to stick on it, and to ride well enough for practical purposes; but in the water if you cannot swim you will drown, and we cannot swim unless we are taught. Again, you are not forced to ride on pain of death, while no one is sure of escaping such a common danger as drowning. Emile shall be as much at home in the water as on land. Why should he not be able to live in every element? If he could learn to fly, he should be an eagle; I would make him a salamander, if he could bear the heat.
People are afraid lest the child should be drowned while he is learning to swim; if he dies while he is learning, or if he dies because he has not learnt, it will be your own fault. Foolhardiness is the result of vanity; we are not rash when no one is looking. Emile will not be foolhardy, though all the world were watching him. As the exercise does not depend on its danger, he will learn to swim the Hellespont by swimming, without any danger, a stream in his father's park; but he must get used to danger too, so as not to be flustered by it. This is an essential part of the apprenticeship I spoke of just now. Moreover, I shall take care to proportion the danger to his strength, and I shall always share it myself, so that I need scarcely fear any imprudence if I take as much care for his life as for my own.
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,
