out and thru in its turn is itself eliminated and destroyed, This the dogmatists answer by saying that they do [not merely] not deny the statement, but even plainly assert it. So they were merely using the words as servants, as it was not possible not to refute one statement by another; just as we a «are accustomed to say there is no such thing as space, and yet we have no alternative but to speak of space for the purpose of argument, though not of positive doctrine, and just as we say nothing comes about by necessity and yet have to speak of necessity. This was the sort of interpretation they used to give ; though things appear to be such and such, they are not such in reality but onlv appear such. And they would say that they sought, not thoughts, since thoughts are evidently thought, but the things in which sensation plays a part. Thus the Pyrrhonean principle, as Aenesidemus says in the introduction to his Pyrrhonics, is but a report on phenomena or on any kind of judgement, a report in which all things are brought to bear on one another, and in the comparison are found to present much anomaly and confusion. As to the contradictions in their doubts, they would first show the ways in which things gain credence, and then by the same methods they would destroy belief in them ; for they say those things gain credence which either the senses are agreed upon or which never or at least rarely change, as well as things which become habitual or are determined by law and those which please or excite wonder. They showedj then, on the basis of that which is contrary to what induces belief, that the probabilities on both sides are equal.
