All these observations combine to prove that the jealous fury of the males of certain animals proves nothing with regard to man; and the exceptional case of those southern regions were polygamy is the established custom, only confirms the rule, since it is the plurality of wives that gives rise to the tyrannical precautions of the husband, and the consciousness of his own weakness makes the man resort to constraint to evade the laws of nature.

Among ourselves where these same laws are less frequently evaded in this respect, but are more frequently evaded in another and even more detestable manner, jealousy finds its motives in the passions of society rather than in those of primitive instinct. In most irregular connections the hatred of the lover for his rivals far exceeds his love for his mistress; if he fears a rival in her affections it is the effect of that self-love whose origin I have already traced out, and he is moved by vanity rather than affection. Moreover, our clumsy systems of education have made women so deceitful, [Footnote: The kind of deceit referred to here is just the opposite of that deceit becoming in a woman, and taught her by nature; the latter consists in concealing her real feelings, the former in feigning what she does not feel. Every society lady spends her life in boasting of her supposed sensibility, when in reality she cares for no one but herself.] and have so over-stimulated their appetites, that you cannot rely even on the most clearly proved affection; they can no longer display a preference which secures you against the fear of a rival.

True love is another matter. I have shown, in the work already referred to, that this sentiment is not so natural as men think, and that there is a great difference between the gentle habit which binds a man with cords of love to his helpmeet, and the unbridled passion which is intoxicated by the fancied charms of an object which he no longer sees in its true light. This passion which is full of exclusions and preferences, only differs from vanity in this respect, that vanity demands all and gives nothing, so that it is always harmful, while love, bestowing as much as it demands, is in itself a sentiment full of equity. Moreover, the more exacting it is, the more credulous; that very illusion which gave rise to it, makes it easy to persuade. If love is suspicious, esteem is trustful; and love will never exist in an honest heart without esteem, for every one loves in another the qualities which he himself holds in honour.

When once this is clearly understood, we can predict with confidence the kind of jealousy which Emile will be capable of experiencing; as there is only the smallest germ of this passion in the human heart, the form it takes must depend solely upon education: Emile, full of love and jealousy, will not be angry, sullen, suspicious, but delicate, sensitive, and timid; he will be more alarmed than vexed; he will think more of securing his lady-love than of threatening his rival; he will treat him as an obstacle to be removed if possible from his path, rather than as a rival to be hated; if he hates him, it is not because he presumes to compete with him for Sophy’s affection, but because Emile feels that there is a real danger of losing that affection; he will not be so unjust and foolish as to take offence at the rivalry itself; he understands that the law of preference rests upon merit only, and that honour depends upon success; he will redouble his efforts to make himself acceptable, and he will probably succeed. His generous Sophy, though she has given alarm to his love, is well able to allay that fear, to atone for it; and the rivals who were only suffered to put him to the proof are speedily dismissed.

But whither am I going? O Emile! what art thou now? Is this my pupil? How art thou fallen! Where is that young man so sternly fashioned, who braved all weathers, who devoted his body to the hardest tasks and his soul to the laws of wisdom; untouched by prejudice or passion, a lover of truth, swayed by reason only, unheeding all that was not hers? Living in softness and idleness he now lets himself be ruled by women; their amusements are the business of his life, their wishes are his laws; a young girl is the arbiter of his fate, he cringes and grovels before her; the earnest Emile is the plaything of a child.

So shift the scenes of life; each age is swayed by its own motives, but the man is the same. At ten his mind was set upon cakes, at twenty it is set upon his mistress; at thirty it will be set upon pleasure; at forty on ambition, at fifty on avarice; when will he seek after wisdom only? Happy is he who is compelled to follow her against his will! What matter who is the guide, if the end is attained. Heroes and sages have themselves paid tribute to this human weakness; and those who handled the distaff with clumsy fingers were none the less great men.

If you would prolong the influence of a good education through life itself, the good habits acquired in childhood must be carried forward into adolescence, and when your pupil is what he ought to be you must manage to keep him what he ought to be. This is the coping-stone of your work. This is why it is of the first importance that the tutor should remain with young men; otherwise there is little doubt they will learn to make love without him. The great mistake of tutors and still more of fathers is to think that one way of living makes another impossible, and that as soon as the child is grown up, you must abandon everything you used to do when he was little. If that were so, why should we take such pains in childhood, since the good or bad use we make of it will vanish with childhood itself; if another way of life were necessarily accompanied by other ways of thinking?

The stream of memory is only interrupted by great illnesses, and the stream of conduct, by great passions. Our tastes and inclinations may change, but this change, though it may be sudden enough, is rendered less abrupt by our habits. The skilful artist, in a good colour scheme, contrives so to mingle and blend his tints that the transitions are imperceptible; and certain colour washes are spread over the whole picture so that there may be no sudden breaks. So should it be with our likings. Unbalanced characters are always changing their affections, their tastes, their sentiments; the only constant factor is the habit of change; but the man of settled character always returns to his former habits and preserves to old age the tastes and the pleasures of his childhood.

If you contrive that young people passing from one stage of life to another do not despise what has gone before, that when they form new habits, they do not forsake the old, and that they always love to do what is right, in things new and old; then only are the fruits of your toil secure, and you are sure of your scholars as long as they live; for the revolution most to be dreaded is that of the age over which you are now watching. As men always look back to this period with regret so the tastes carried forward into it from childhood are not easily destroyed; but if once interrupted they are never resumed.

Most of the habits you think you have instilled into children and young people are not really habits at all; they have only been acquired under compulsion, and being followed reluctantly they will be cast off at the first opportunity. However long you remain in prison you never get a taste for prison life; so aversion is increased rather than diminished by habit. Not so with Emile; as a child he only did what he could do willingly and with pleasure, and as a man he will do the same, and the force of habit will only lend its help to the joys of freedom. An active life, bodily labour, exercise, movement, have become so essential to him that he could not relinquish them without suffering. Reduce him all at once to a soft and sedentary life and you condemn him to chains and imprisonment, you keep him in a condition of thraldom and constraint; he would suffer, no doubt, both in health and temper. He can scarcely breathe in a stuffy room, he requires open air, movement, fatigue. Even at Sophy’s feet he cannot help casting a glance at the country and longing to explore it in her company. Yet he remains if he must; but he is anxious and ill at ease; he seems to be struggling with himself; he remains because he is a captive. “Yes,” you will say, “these are necessities to which you have subjected him, a yoke which you have laid upon him.” You speak truly, I have subjected him to the yoke of manhood.
