Perhaps, however, they will maintain that it was in the matter of _logic_ that Erasistratus associated himself with the Peripatetic philosophers? Here they show ignorance of the fact that these philosophers never brought forward false or inconclusive arguments, while the Erasistratean books are full of them. So perhaps somebody may already be asking, in some surprise, what possessed Erasistratus that he turned so completely from the doctrines of Hippocrates, and why it is that he takes away the attractive faculty from the biliary[204] passages in the liver--for we have sufficiently discussed the kidneys--alleging [as the cause of bile-secretion] a favourable situation, the narrowness of vessels, and _a common space_ into which the veins from the gateway [of the liver][205] conduct the unpurified blood, and from which, in the first place, the [biliary] passages take over the bile, and secondly, the [branches] of the vena cava take over the purified blood. For it would not only have done him no harm to have mentioned the idea of _attraction_, but he would thereby have been able to get rid of countless other disputed questions.
