Such relativity is no less true in regard to the ratiocinative combinations of each individual, than in regard to his percipient capacities _ib._ Evidence from Plato proving implication of Subject and Object, in regard to the intelligible world 121 The Protagorean measure is even more easily shown in reference to the intelligible world than in reference to sense 122 Object always relative to Subject--Either without the other, impossible. Plato admits this in Sophistes 126 Plato's representation of the Protagorean doctrine in intimate conjunction with the Herakleitean 126 Relativity of sensible facts, as described by him _ib._ Relations are nothing in the object purely and simply without a comparing subject 127 Relativity twofold--to the comparing Subject--to another object, besides the one directly described _ib._ Statement of the doctrine of Herakleitus--yet so as to implicate it with that of Protagoras 128 Agent and Patient--No absolute Ens 129 Arguments derived from dreams, fevers, &c., may be answered 130 Exposition of the Protagorean doctrine, as given here by Sokrates is to a great degree just. You cannot explain the facts of consciousness by independent Subject and Object 131 Plato's attempt to get behind the phenomena. Reference to a double potentiality--Subjective and Objective 133 Arguments advanced by the Platonic Sokrates against the Protagorean doctrine. He says that it puts the wise and foolish on a par--that it contradicts the common consciousness. Not every one, but the wise man only, is a measure 135 In matters of present sentiment every man can judge for himself. Where future consequences are involved special knowledge is required 136 Plato, when he impugns the doctrine of Protagoras, states that doctrine without the qualification properly belonging to it. All belief relative to the condition of the believing mind 137 All exposition and discussion is an assemblage of individual judgments and affirmations. This fact is disguised by elliptical forms of language 139 Argument--That the Protagorean doctrine equalises all men and animals. How far true. Not true in the sense requisite to sustain Plato's objection 141 Belief on authority is true to the believer himself--The efficacy of authority resides in the believer's own mind 142 Protagorean formula--is false, to those who dissent from it 143 Plato's argument that the wise man alone is a measure--Reply to it _ib._ Plato's argument as to the distinction between present sensation and anticipation of the future 145 The formula of Relativity does not imply that every man believes himself to be infallible _ib._ Plato's argument is untenable--That if the Protagorean formula be admitted, dialectic discussion would be annulled--The reverse is true--Dialectic recognises the autonomy of the Individual mind 146 Contrast with the Treatise De Legibus--Plato assumes infallible authority--sets aside dialectic 148
