I do not, however, mean, that, for the knowledge and cure of such disorders, as often befall those who do not live regularly, there is no occasion for a physician, and that his assistance ought to be slighted. For, if we are apt to receive such great comfort from friends, who come to visit us in our illness, though they do no more than testify their concern for us, and bid us be of good cheer; how much more regard ought we to have for the physician, who is a friend that comes to see us in order to relieve us, and promises us a cure? But for the bare purpose of keeping ourselves in good health, I am of the opinion, that we should consider as a physician this regular life, which, as we have seen, is our natural and proper physic, since it preserves men, even those of a bad constitution, in health; makes them live sound and hearty to the age of one hundred and upwards; and prevents their dying of sickness, or through a corruption of their humours, but merely by a dissolution of their radical moisture, when quite exhausted; all which effects several wise men have attributed to potable gold, and the elixir, sought for by many, but discovered by few. However to confess the truth, men, for the most part, are very sensual and intemperate, and love to satisfy their appetites, and to commit every excess; therefore, seeing that they cannot avoid being greatly injured by such excess, as often as they are guilty of it, they, by way of apologizing for their conduct, say, that it is better to live ten years less, and enjoy themselves; not considering, of what importance are ten years more of life, especially a healthy life, and at a maturer age; when men become sensible of their progress in knowledge and virtue, which cannot attain to any degree of perfection before this period of life.
