SUBSECT. VI.—_Parents a cause by Propagation_.
That other inward inbred cause of Melancholy is our temperature, in whole or part, which we receive from our parents, which [1312]Fernelius calls Praeter naturam, or unnatural, it being an hereditary disease; for as he justifies [1313]Quale parentum maxime patris semen obtigerit, tales evadunt similares spermaticaeque paries, quocunque etiam morbo Pater quum generat tenetur, cum semine transfert, in Prolem; such as the temperature of the father is, such is the son's, and look what disease the father had when he begot him, his son will have after him; [1314]and is as well inheritor of his infirmities, as of his lands. And where the complexion and constitution of the father is corrupt, there ([1315]saith Roger Bacon) the complexion and constitution of the son must needs be corrupt, and so the corruption is derived from the father to the son. Now this doth not so much appear in the composition of the body, according to that of Hippocrates, [1316]in habit, proportion, scars, and other lineaments; but in manners and conditions of the mind, Et patrum in natos abeunt cum semine mores. Seleucus had an anchor on his thigh, so had his posterity, as Trogus records, lib. 15. Lepidus, in Pliny l. 7. c. 17, was purblind, so was his son. That famous family of Aenobarbi were known of old, and so surnamed from their red beards; the Austrian lip, and those Indian flat noses are propagated, the Bavarian chin, and goggle eyes amongst the Jews, as [1317] Buxtorfius observes; their voice, pace, gesture, looks, are likewise derived with all the rest of their conditions and infirmities; such a mother, such a daughter; their very [1318]affections Lemnius contends to follow their seed, and the malice and bad conditions of children are many times wholly to be imputed to their parents; I need not therefore make any doubt of Melancholy, but that it is an hereditary disease. [1319] Paracelsus in express words affirms it, lib. de morb. amentium to. 4. tr. 1; so doth [1320]Crato in an Epistle of his to Monavius. So doth Bruno Seidelius in his book de morbo incurab. Montaltus proves, cap. 11, out of Hippocrates and Plutarch, that such hereditary dispositions are frequent, et hanc (inquit) fieri reor ob participatam melancholicam intemperantiam (speaking of a patient) I think he became so by participation of Melancholy. Daniel Sennertus, lib. 1. part 2. cap. 9, will have his melancholy constitution derived not only from the father to the son, but to the whole family sometimes; Quandoque totis familiis hereditativam, [1321]Forestus, in his medicinal observations, illustrates this point, with an example of a merchant, his patient, that had this infirmity by inheritance; so doth Rodericus a Fonseca, tom. 1. consul. 69, by an instance of a young man that was so affected ex matre melancholica, had a melancholy mother, et victu melancholico, and bad diet together. Ludovicus Mercatus, a Spanish physician, in that excellent Tract which he hath lately written of hereditary diseases, tom. 2. oper. lib. 5, reckons up leprosy, as those [1322]Galbots in Gascony, hereditary lepers, pox, stone, gout, epilepsy, &c. Amongst the rest, this and madness after a set time comes to many, which he calls a miraculous thing in nature, and sticks for ever to them as an incurable habit. And that which is more to be wondered at, it skips in some families the father, and goes to the son, [1323]or takes every other, and sometimes every third in a lineal descent, and doth not always produce the same, but some like, and a symbolizing disease. These secondary causes hence derived, are commonly so powerful, that (as [1324]Wolfius holds) saepe mutant decreta siderum, they do often alter the primary causes, and decrees of the heavens. For these reasons, belike, the Church and commonwealth, human and Divine laws, have conspired to avoid hereditary diseases, forbidding such marriages as are any whit allied; and as Mercatus adviseth all families to take such, si fieri possit quae maxime distant natura, and to make choice of those that are most differing in complexion from them; if they love their own, and respect the common good.
