their discoveries, and thought the Art worthy of being ascribed to
a god, as is the established belief. For they did not suppose that
the dry or the moist, the hot or the cold, or any of these are either
injurious to man, or that man stands in need of them, but whatever
in each was strong, and more than a match for a man's constitution,
whatever he could not manage, that they held to be hurtful, and sought
to remove. Now, of the sweet, the strongest is that which is intensely
sweet; of the bitter, that which is intensely bitter; of the acid,
that which is intensely acid; and of all things that which is extreme,
for these things they saw both existing in man, and proving injurious
to him. For there is in man the bitter and the salt, the sweet and
the acid, the sour and the insipid, and a multitude of other things
having all sorts of powers both as regards quantity and strength.
These, when all mixed and mingled up with one another, are not apparent,
neither do they hurt a man; but when any of them is separate, and
stands by itself, then it becomes perceptible, and hurts a man. And
thus, of articles of food, those which are unsuitable and hurtful
to man when administered, every one is either bitter, or intensely
so, or saltish or acid, or something else intense and strong, and
therefore we are disordered by them in like manner as we are by the
secretions in the body. But all those things which a man eats and
drinks are devoid of any such intense and well-marked quality, such
as bread, cake, and many other things of a similar nature which man
is accustomed to use for food, with the exception of condiments and
confectioneries, which are made to gratify the palate and for luxury.
And from those things, when received into the body abundantly, there
is no disorder nor dissolution of the powers belonging to the body;
but strength, growth, and nourishment result from them, and this for
no other reason than because they are well mixed, have nothing in
them of an immoderate character, nor anything strong, but the whole
forms one simple and not strong substance.
PART 15
I cannot think in what manner they who advance this doctrine, and
transfer Art from the cause I have described to hypothesis, will cure
men according to the principle which they have laid down. For, as
far as I know, neither the hot nor the
