Knowledge, always relative to some object known. Postulate or divination of a Science of Teleology 169 Courage and Temperance, handled both by Plato and by Aristotle. Comparison between the two 170 CHAPTER XX. LYSIS. Analogy between Lysis and Charmides. Richness of dramatic incident in both. Youthful beauty 172 Scenery and personages of the Lysis _ib._ Origin of the conversation. Sokrates promises to give an example of the proper way of talking to a youth, for his benefit 173 Conversation of Sokrates with Lysis _ib._ Lysis is humiliated. Distress of Hippothalês 177 Lysis entreats Sokrates to talk in the like strain to Menexenus _ib._ Value of the first conversation between Sokrates and Lysis, as an illustration of the Platonico-Sokratic manner 177 Sokrates begins to examine Menexenus respecting friendship. Who is to be called a friend? Halt in the dialogue 178 Questions addressed to Lysis. Appeal to the maxims of the poets. Like is the friend of like. Canvassed and rejected _ib._ Other poets declare that likeness is a cause of aversion; unlikeness, of friendship. Reasons _pro_ and _con_. Rejected 179 Confusion of Sokrates. He suggests, That the Indifferent (neither good nor evil) is friend to the Good 180 Suggestion canvassed. If the Indifferent is friend to the Good, it is determined to become so by the contact of felt evil, from which it is anxious to escape 180 Principle illustrated by the philosopher.

The Primum Amabile, or object originally dear to us, _per se_: by relation or resemblance to which other objects become dear _ib._ The cause of love is desire. We desire that which is akin to us or our own 182 Good is of a nature akin to every one, evil is alien to every one. Inconsistency with what has been previously laid down 183 Failure of the enquiry. Close of the dialogue 184 Remarks. No positive result. Sokratic purpose in analysing the familiar words--to expose the false persuasion of knowledge _ib._ Subject of Lysis. Suited for a Dialogue of Search. Manner of Sokrates, multiplying defective explanations, and showing reasons why each is defective 185 The process of trial and error is better illustrated by a search without result than with result. Usefulness of the dialogue for self-working minds 186 Subject of friendship, handled both by the Xenophontic Sokrates, and by Aristotle _ib._ Debate in the Lysis partly verbal, partly real. Assumptions made by the Platonic Sokrates, questionable, such as the real Sokrates would have found reason for challenging 188 Peculiar theory about friendship broached by Sokrates. Persons neither good nor evil by nature, yet having a superficial tinge of evil, and desiring good to escape from it 189
