Although the longest term of human life, and the probability, at any given age, of reaching this term, have been computed, nothing is more uncertain than the continuance of each individual life: very few attain the maximum. The greatest risks in life are at its beginning; the less one has lived, the less prospect he has of living.

Of all children born, only about half reach youth; and it is probable that your pupil may never attain to manhood. What, then, must be thought of that barbarous education which sacrifices the present to an uncertain future, loads the child with every description of fetters, and begins, by making him wretched, to prepare for him some far-away indefinite happiness he may never enjoy! Even supposing the object of such an education reasonable, how can we without indignation see the unfortunate creatures bowed under an insupportable yoke, doomed to constant labor like so many galley-slaves, without any certainty that all this toil will ever be of use to them! The years that ought to be bright and cheerful are passed in tears amid punishments, threats, and slavery. For his own good, the unhappy child is tortured; and the death thus summoned will seize on him unperceived amidst all this melancholy preparation. Who knows how many children die on account of the extravagant prudence of a father or of a teacher? Happy in escaping his cruelty, it gives them one advantage; they leave without regret a life which they know only from its darker side.[2]

Émile — Part 29

O men, be humane! it is your highest duty; be humane to all conditions of men, to every age, to everything not alien to mankind. What higher wisdom is there for you than humanity? Love childhood; encourage its sports, its pleasures, its lovable instincts. Who among us has not at times looked back with regret to the age when a smile was continually on our lips, when the soul was always at peace? Why should we rob these little innocent creatures of the enjoyment of a time so brief, so transient, of a boon so precious, which they cannot misuse? Why will you fill with bitterness and sorrow these fleeting years which can no more return to them than to you? Do you know, you fathers, the moment when death awaits your children? Do not store up for yourselves remorse, by taking from them the brief moments nature has given them. As soon as they can appreciate the delights of existence, let them enjoy it. At whatever hour God may call them, let them not die without having tasted life at all.
