longer follow. 'But must not the thought be of something which is the same in all and is the idea? And if the world partakes in the ideas, and the ideas are thoughts, must not all things think? Or can thought be without thought?' 'I acknowledge the unmeaningness of this,' says Socrates, 'and would rather have recourse to the explanation that the ideas are types in nature, and that other things partake of them by becoming like them.' 'But to become like them is to be comprehended in the same idea; and the likeness of the idea and the individuals implies another idea of likeness, and another without end.' 'Quite true.' 'The theory, then, of participation by likeness has to be given up. You have hardly yet, Socrates, found out the real difficulty of maintaining abstract ideas.' 'What difficulty?' 'The greatest of all perhaps is this: an opponent will argue that the ideas are not within the range of human knowledge; and you cannot disprove the assertion without a long and laborious demonstration, which he may be unable or unwilling to follow. In the first place, neither you nor any one who maintains the existence of absolute ideas will affirm that they are subjective.' 'That would be a contradiction.' 'True; and therefore any relation in these ideas is a relation which concerns themselves only; and the objects which are named after them, are relative to one another only, and have nothing to do with the ideas themselves.' 'How do you mean?' said Socrates. 'I may illustrate my meaning in this way: one of us has a slave; and the idea of a slave in the abstract is relative to the idea of a master in the abstract; this correspondence of ideas, however, has nothing to do with the particular relation of our slave to us.--Do you see my meaning?' 'Perfectly.' 'And absolute knowledge in the same way corresponds to absolute truth and being, and particular knowledge to particular truth and being.' Clearly.' 'And there is a subjective knowledge which is of subjective truth, having many kinds, general and particular. But the ideas themselves are not subjective, and therefore are not within our ken.' 'They are not.' 'Then the beautiful and the good in their own nature are unknown to us?' 'It would seem so.' 'There is a worse consequence yet.' 'What is that?' 'I think we must admit that absolute knowledge is the most exact knowledge, which we must therefore attribute to God. But then see what follows: God, having this exact knowledge, can have no knowledge of human things, as we have divided the two spheres, and forbidden any passing from one to the other:--the gods have knowledge and authority in their world only, as we have in ours.' 'Yet, surely, to deprive God of knowledge is monstrous.'--'These are some of the difficulties which are involved in the assumption of absolute ideas; the learner will find them nearly impossible to understand, and the teacher who has to impart them will require superhuman ability; there will always be a suspicion, either that they have no existence, or are beyond human knowledge.' 'There I agree with you,' said Socrates. 'Yet if these difficulties induce you to give up universal ideas, what becomes of the mind? and where are the reasoning and reflecting powers? philosophy is at an end.' 'I certainly do not see my way.' 'I think,' said Parmenides, 'that this arises out of your attempting to define abstractions, such as the good and the beautiful and the just, before you have had sufficient previous training; I noticed your deficiency when you were talking with Aristoteles, the day before yesterday. Your enthusiasm is a wonderful gift; but I fear that unless you discipline yourself by dialectic while you are young, truth will elude your grasp.' 'And what kind of discipline would you recommend?' 'The training which you heard Zeno practising; at the same time, I admire your saying to him that you did not care to consider the difficulty in reference to visible objects, but only in relation to ideas.' 'Yes; because I think that in visible objects you may easily show any number of inconsistent consequences.' 'Yes; and you should consider, not only the consequences which follow from a given hypothesis, but the consequences also which follow from the denial of the hypothesis. For example, what follows from the assumption of the existence of the many, and the counter-argument of what follows from the denial of the existence of the many: and similarly of likeness and unlikeness, motion, rest, generation, corruption, being and not being. And the consequences must include consequences to the things supposed and to other things, in themselves and in relation to one another, to individuals whom you select, to the many, and to the all; these
