1. Symposium III and Lysis Philosophy of Love and Sex

2. What is Beauty Itself? The Form of X is what makes things that are X be X. The Form of the Human Being is what makes human beings be human. The Form of Beauty is what makes beautiful things be beautiful. The Forms do not change. The Forms are not culturally relative. The Forms are really real not merely in mind or merely abstract.

3. Why believe in the Forms? Learning conceptsstandards, etc. Explanation of commonalities.

4. Too impersonal? Shouldnt the highest love be love of persons? But after achieving the highest, one is better at the lower kinds of love, for one truly understands what it is that is lovable about persons, laws, mathematics, etc.

5. The framing Why the weird framingwhy Diotima tells all this stuff, not Socrates? Suggestion: One of Socrates most famous claims is that he knows nothing. Thus, he has not achieved the knowledge of the Form of Beauty, and can only rely on what others tell him. The point is to encourage us to pursue Platos educational plan for ourselves.

6. Lysis Philia not eros Aporetic –Ends without a solution, in a puzzle, with apparently no way through (aporia). Puzzle: who is whose friend? And what are the reasons for friendship?

7. Who is whose friend? Option 1: If x loves y, then x is ys friend. Problem: How can someone be your friend if you hate them? Option 2: If x loves y, then y is xs friend. Problem: How can you be the friend of someone you hate? Option 3: x is ys friend iff x loves y and y loves x Problem 1: Parents and children Problem 2: What if x doesnt know that y loves x?

8. Like is a friend to like Problem: Evil people might be like each other but no friends of each other. Response: Evil is unstable so evil people wont stay like each other for long. The suggestion is that likeness is a reason for friendship. Problem: Is there any good or harm that a like thing can do to a like thing, which it cannot also do to itself? (214e-215a) The importance of complementarity. Eros in the Symposium was linked to desire, philia here seems to be linked to need.

9. A definition of friendly love? [a] That which is neither good nor evil is a friend to [b] good on account of [c] an evil to which it [i.e., a] is an enemy, for the sake of [d] a good to which it is a friend (219B). If the son is sick, and the doctor prescribes wine for the son, the father (a: neither good nor evil) is friends to the wine (b: good) on account of sickness (c: an evil), for the sake of health (d: a good). Refinement: can omit the evil. Health would be valuable even if there were no sickness. [a] That which is neither good nor evil is a friend to [b] good, for the sake of [d] a good to which it [i.e., a] is a friend Puzzle: This seems to generates an endless regress of goods. A is a friend to B for the sake of C; A is a friend to C for the sake of D; A is a friend to D for the sake of E. Solution: Eventually we reach a case where good b = good d, and A is a friend to it for its own sake. Some things we are friends with for their own sake. What are these? Persons? Forms? Happiness?

10. The ending At the end, Socrates explores what it is that we desirethat which is natural to human beings. He is unsatisfied with his answers. The discussion ends with the paradox that we dont know what friendship is even though we think we are friends.
