Here it may be objected, and some actually object, that he, who leads a regular life, having constantly, when well, made use of food fit for the sick, and in small quantities, has no resource left in case of illness. To this I might, in the first place, answer, that nature, desirous to preserve man in good health as long as possible, informs him, herself, how he is to act in time of illness; for she immediately deprives him, when sick, of his appetite, in order that he may eat but little; because nature (as I have said already) is satisfied with little; wherefore, it is requisite, that a man, when sick, whether he has been a regular or irregular liver, should use no meats, but such as are suited to his disorder; and of these even in a much smaller quantity than he was wont to do, when in health. For were he to eat as much as he used to do, he would die by it; because it would be only adding to the burden, with which nature was already oppressed, by giving her a greater quantity of food, than she can in such circumstances support; and this, I imagine, would be a sufficient caution to any sick person. But, independent of all this, I might answer some others, and still better, that whoever leads a regular life, cannot be sick; or, at least, but seldom, and for a short time; because, by living regularly, he extirpates every seed of sickness; and thus, by removing the cause, prevents the effect; so that he, who pursues a regular course of life, need not be apprehensive of illness, as he need not be afraid of the effect, who has guarded against the cause. Since it therefore appears that a regular life is so profitable and virtuous, so lovely and so holy, it ought to be universally followed and embraced; and more so, as it does not clash with the means or duties of any station, but is easy to all; because, to lead it, a man need not tie himself down to eat so little as I do, or not to eat fruit, fish, and other things of that kind, from which I abstain, who eat little, because it is sufficient for my puny and weak stomach; and fruit, fish, and other things of that kind, disagree with me, which is my reason for not touching them. Those, however, with whom such things agree, may, and ought to eat of them; since they are not by any means forbid the use use of such sustinance. But, then, both they, and all others, are forbid to eat a greater quantity of any kind of food, even of that which agrees with them, than what their stomachs can easily digest; the same is to be understood of drink. Hence it is that those, with whom nothing disagrees, are not bound to observe any rule but that relating to the quantity, and not to the quality, of their food; a rule which they may, without the least difficulty in the world, comply with.
