Epitome of the Complete Works of Galen

Why it does not happen that everyone falls ill from the same cause.

because neither the quantity or activity of the cause happens to them always in the same way, and because the bodies of living beings differ greatly from one another.
What is required to generate a fever.

Indeed, for a fever to be ignited in a body, it is necessary that the body itself be adapted and capable of receiving febrile heat; that the efficient cause be strong; and that it possess the right time and proximity to the patient: namely, so that it may persist in the action longer, and prevail over the body that is to suffer.
Antecedent causes are said to be those that arise in the body; procatarctic, those that arrive from the outside.

Furthermore, the causes that arise in the human body contrary to nature are called antecedent causes; but those that occur by arriving from the outside are called procatarctic predisposing/external.
Causes of immoderate coldness.

There are also many causes of coldness: such as the proximity of cold things, the quantity and quality of foods, also constriction and relaxation, and finally idleness and immoderate movement: from which occasions it is also established that the fire itself is extinguished.
Whence apoplexy is sometimes contracted.

Wine taken in moderation strangely increases heat.

Although wine taken in moderation, since it is a familiar food, strangely increases heat.
All foods that nourish greatly, if taken immoderately, generate cold diseases.

In general, however, all the best foods, which bring much nourishment to an animal, if they are taken beyond measure, generate cold diseases: just as also other things, which, being refrigerator-natured, are ingested in a similar way. According to the third genus of cause, namely constriction, the habit of the body is also very often cooled: such as that which sometimes induces heavy sleep, lethargy, and apoplexy. The body is then especially tormented by constriction while the veins themselves and the arteries swell and distend with blood, so that no empty space is left into which, when they dilate, they can receive the ambient air. While they are defrauded of this, their innate heat
