 				<p>Here I find myself obliged to finish my dissertation on my new method of lovemaking; it seems to me that it is becoming rather obscure, and so a little more explanation of the nature of this discovery will not be out of place, seeing that it does not become everybody at all times of life.</p>
 				<p>For instance, I would not recommend it to anybody under twenty. The inventor himself did not practice it at that period of his life. To make full use of the invention one must have experienced all the sorrows of life without being disheartened, and all its pleasures without being surfeited. The difficulty lies in this, that it is especially useful at that period of life when reason counsels us to abandon the habits of youth, and it can then transition or intermediary step between the age of pleasure and the age of wisdom⁠—a step (as all moralists have observed) fraught with immense difficulties. Few, indeed, have the courage to take the leap boldly; and often, after having taken it, they feel bored to death on the other side; and, shamefaced, and with snowy locks, they are compelled to re-cross the ditch. And this is exactly what they will be spared by adopting my new method of lovemaking. The greatest number of our pleasures in reality being nothing but the play of the imagination, it is essential to offer it an innocent field, in order to divert it from the objects we ought to renounce, almost in the same way as one offers playthings to children when one refuses them sweetmeats.</p>
-				<p>In this way we gain time to obtain a firm footing on the threshhold of wisdom, without being too forcibly reminded that we have reached this stage of life; and, moreover, the circumstance that one attains to it by the path of folly, will greatly facilitate its access to most people.</p>

 				<p>I really believe that I was not deceived in the hope of being useful, when I seized my pen, and it only remains for me to defend myself against the promptings of self-esteem, which I might lawfully feel at having revealed truths like these to mankind.</p>
