Phaedo 74a-76e

Some thoughts: this is deliberately flying at a higher level than an "argument analysis" flies: what I mean by that is that I am using references like "74a-c" and NOT including line numbers. Another thing: I am trying to stir the pot here, to make you think about alternatives to Plato's ideas that might help us understand but also questions Plato's ideas.
 I hope that it will inform and enrich your argument analyses of this passage.

  1. 74a-c
    1. There is something that is equal, the equal itself.
      1. Note well that this means that the Form of Equality is itself Equal
        1. "self-predication of forms" means that the name of a form can be applied to the form itself: thus the Form of the Equal is equal.
      2. What can that possibly mean?
      3. It makes better sense, perhaps, to say that the Form of Redness is itself red, but what sense does it make to say that a single thing, by itself, is equal? Isn't "equality" inherently a relative thing such that a thing itself cannot be equal: it can only be equal to another thing? So how can the equal itself be one thing AND be equal (to what?)?
      4. Some, including Aristotle, Metaphysics 987b14-18, have suggested that Plato posited the Form (Equality)  as well as Intermediates (things that are perfectly equal)
        1. But such things as Intermediates (like mathematical objects) are not explicitly mentioned by Plato
      5. Take the dictionary definition of 'equality':
        1. the state of having the same measure, quantity, amount, or number as another or others
      6. It uses a concept "same" which might be held to 'beg the question': is it just another way to say 'equal'?
      7. It also mentions 'others' which implies one thing and other things, not just one thing (but others may refer to people: see below)
      8. But is that dictionary definition itself "equal" in any meaningful way?
    2. Sensible things sometimes appear equal to one and unequal to another
    3. Equality always appears equal (to what? whom?).
      1. This moves away from what the 'equal' is to how it 'appears':
      2. anyone who encounters it will realize that it is equal and
      3. it cannot appear otherwise to anyone.
    4. Therefore, by 2 and 3, sensible equal things are not the same (as Equality).
    5. But from the sensible equal things, we come to grasp Equality.
  2. 74c-75c
    1. Seeing one thing and thinking of another was previously agreed to be recollection.
    2. Two sensible things that appear equal are somehow 'deficient' in their equality compared with Equality, which is 'really' equal.
    3. Whenever someone realizes that a thing is 'deficient' in some quality compared with another 'reality,' it must be the case that the person has prior knowledge of that other 'reality.'
    4. The only way we can grasp Equality (in our bodily state) is thru our senses.
    5. But our senses make us realize that everything we see falls short of its goal.
    6. Therefore, before we perceived these things, we must have had knowledge of Equality.
    7. Since birth, we have had sense perceptions (i.e. we have been in a bodily state).
    8. Thus our knowledge of Equality must predate birth (it must predate our bodily state).
  3. 75c-76e
    1.  Therefore, we knew before birth Equality, Greatness, Smallness, Beautiful, Good, Just, Pious, etc.
    2. If we had it then, but don't have it now, and we discover it by looking at sensibles, we are recollecting knowledge of these things.
    3. Thus learning is recollection.
    4. And if we had knowledge of these things before birth, we must have existed before birth and been intelligent then.
    5. If the Forms exist, and we refer the things we perceive to them, then just as they exist, so our soul must have existed before birth.
    6. If the Forms do not exist, then the argument for the soul pre-existing our current bodily existence is futile.
