They say French is more chaste than other languages; for my own part I think it more obscene; for it seems to me that the purity of a language does not consist in avoiding coarse expressions but in having none.  Indeed, if we are to avoid them, they must be in our thoughts, and there is no language in which it is so difficult to speak with purity on every subject than French.  The reader is always quicker to detect than the author to avoid a gross meaning, and he is shocked and startled by everything.  How can what is heard by impure ears avoid coarseness?  On the other hand, a nation whose morals are pure has fit terms for everything, and these terms are always right because they are rightly used.  One could not imagine more modest language than that of the Bible, just because of its plainness of speech.  The same things translated into French would become immodest.  What I ought to say to Emile will sound pure and honourable to him; but to make the same impression in print would demand a like purity of heart in the reader.

I should even think that reflections on true purity of speech and the sham delicacy of vice might find a useful place in the conversations as to morality to which this subject brings us; for when he learns the language of plain-spoken goodness, he must also learn the language of decency, and he must know why the two are so different.  However this may be, I maintain that if instead of the empty precepts which are prematurely dinned into the ears of children, only to be scoffed at when the time comes when they might prove useful, if instead of this we bide our time, if we prepare the way for a hearing, if we then show him the laws of nature in all their truth, if we show him the sanction of these laws in the physical and moral evils which overtake those who neglect them, if while we speak to him of this great mystery of generation, we join to the idea of the pleasure which the Author of nature has given to this act the idea of the exclusive affection which makes it delightful, the idea of the duties of faithfulness and modesty which surround it, and redouble its charm while fulfilling its purpose; if we paint to him marriage, not only as the sweetest form of society, but also as the most sacred and inviolable of contracts, if we tell him plainly all the reasons which lead men to respect this sacred bond, and to pour hatred and curses upon him who dares to dishonour it; if we give him a true and terrible picture of the horrors of debauch, of its stupid brutality, of the downward road by which a first act of misconduct leads from bad to worse, and at last drags the sinner to his ruin; if, I say, we give him proofs that on a desire for chastity depends health, strength, courage, virtue, love itself, and all that is truly good for man—­I maintain that this chastity will be so dear and so desirable in his eyes, that his mind will be ready to receive our teaching as to the way to preserve it; for so long as we are chaste we respect chastity; it is only when we have lost this virtue that we scorn it.
