VI. It is commonly said of Pyrrho, who was by so much the most famous of all the sceptics, that he in a manner obscured the others, by giving his name to the system of universal doubt, which at this day is called Pyrrhonism, and the sectaries of it Pyrrhonists; and he was so positive in maintaining, that we should suspend our opinion, with respect to all we saw, or felt, that he would not turn the least aside, to avoid being run over by a mad horse, or bit by a mad dog; nor would he slacken his pace, although he was warned that he was advancing near the edge of a precipice; and that he would have perished a thousand times by these dangers, if his friends, who were attentive to his safety, had not prevented his running headlong into them. But although this account of him is much vulgarized, I do not know whether any other antient author, except Antigonus Carystius, a Greek historian, who was contemporary with, or lived very nearly in the days of Pyrrho, has vouched the truth of it; at least the learned La Mothe de la Vayer, quotes him as the only author, who attests the relation; and it is even doubtful whether Antigonus Carystius asserts the thing positively, because in the _Præparat. Evang. lib. 14. cap. 18._ of Eusebius, we find this author quoted for a fact, which contradicts that relation; which is, that Pyrrho, when a dog was once about to run at him, climbed up a tree to get out of his way, and avoid the danger. Upon which occasion, those who were present, raillied him upon the difference there was between his doctrine and his practice.
