Symposium

How I wish, said Socrates, taking his place as he was desired, that wisdom could be infused by touch, out of the fuller into the emptier man, as water runs through wool out of a fuller cup into an emptier one; if that were so, how greatly should I value the privilege of reclining at your side! For you would have filled me full with a stream of wisdom plenteous and fair; whereas my own is of a very mean and questionable sort, no better than a dream.
