Of these demonstrations, one characteristic feature is, that they are presented in antagonising pairs or Antinomies: except the third, which professes to mediate between the first and second, though only by introducing new difficulties. We have four distinct Antinomies: the first and second, the fourth and fifth, the sixth and seventh, the eighth and ninth, stand respectively in emphatic contradiction with each other. Moreover, to take the demonstrations separately--the first, fifth, seventh, ninth, end in conclusions purely negative: the other four end in double and contradictory conclusions. The purpose is formally proclaimed, of showing that the same premisses, ingeniously handled, can be made to yield these contradictory results.[47] No attempt is made to reconcile the contradictions, except partially by means of the third, in reference to the two preceding. In regard to the fourth and fifth, sixth and seventh, eighth and ninth, no hint is given that they can be, or afterwards will be, reconciled. The dialogue concludes abruptly at the end of the ninth demonstration, with these words: "We thus see that--whether Unum exists or does not exist--Unum and Cætera both are, and are not, all things in every way--both appear, and do not appear, all things in every way--each in relation to itself, and each in relation to the other".[48] Here is an unqualified and even startling announcement of double and contradictory conclusions, obtained from the same premisses both affirmative and negative: an announcement delivered too as the fulfilment of the purpose of Parmenides. Nothing is said at the end to intimate how the demonstrations are received by Sokrates, nor what lesson they are expected to administer to him: not a word of assent, or dissent, or surprise, or acknowledgment in any way, from the assembled company, though all of them had joined in entreating Parmenides, and had expressed the greatest anxiety to hear his dialectic exhibition. Those who think that an abrupt close, or an abrupt exordium, is sufficient reason for declaring a dialogue not to be the work of Plato (as Platonic critics often argue), are of course consistent in disallowing the Parmenides. For my part, I do not agree in the opinion. I take Plato as I find him, and I perceive both here and in the Protagoras and elsewhere, that he did not always think it incumbent upon him to adapt the end of his dialogues to the beginning. This may be called a defect, but I do not feel called upon to make out that Plato's writings are free from defects; and to acknowledge nothing as his work unless I can show it to be faultless.
