en-wikipedia-org-190		On Passions - Wikipedia			.html	text/html	5535	528	74	The principal source for the On Passions is the polemical commentary by Galen in his On the Doctrines of Hippocrates and Plato which contains most of the surviving quotations.[15] The other main source is Cicero's Tusculan Disputations Book IV which contains a discussion of the Stoic passions which is derived from Chrysippus.[15] A small amount of supplementary information is provided by writers such as Diogenes Laërtius, Stobaeus, Calcidius, and Origen.[15] Cicero uses Chrysippus' On Passions as a major source for the fourth book of his Tusculan Disputations.[28] Some passages in his third book are also drawn from the same source.[28] Cicero may well have used an epitome made by a later Stoic rather than the full text.[28] He provides extra details not mentioned by Galen, and is comparatively unbiased.[28] However, there are no direct quotations from Chrysippus in Cicero's account; he mixes in material drawn from other philosophy schools; and he intersperses his own comments.[29] 	./cache/en-wikipedia-org-190.html	./txt/en-wikipedia-org-190.txt
