Meaning
Haptesthai can mean bodily touching, taking hold of an object of thought, or attacking. Rheō supplies a material process for the first of these settings: water flows through wool from a fuller cup to an emptier one.
Use in the book
Agathon invites Socrates to recline beside him so that touch may communicate the wise thing supposedly discovered in the porch. Socrates answers that it would be fine if wisdom behaved like water passing through wool between cups. The sentence is conditional, not an endorsed physical theory of education. He then reverses Agathon’s estimate of the two men, saying that he himself would gain much brilliant wisdom from his host. Agathon calls him insolent.
The scene tests a tempting idea of learning: proximity to a possessor would be enough to fill a deficit. Alcibiades later proposes a comparable exchange, expecting bodily favour to secure everything Socrates knows. In both scenes an attraction to wisdom is real, but the proposed mode of acquisition is inadequate or unverified.
The later occurrences of touching should neither be ignored nor collapsed into this joke. At 209c Diotima’s pregnant soul touches and associates with the beautiful companion, giving birth and nurturing something together. At 211b one nearly touches the goal; at 212a contact with what is true explains the production of true rather than merely imaged virtue. The family can thus mark fruitful encounter as well as a mistaken shortcut. At Delium its hostile sense, laying hands on a fighter, supplies a reminder that the verb itself has no single philosophical meaning.

Translation in this edition
At 175c the words “by touching you” are printed from T and W, while B omits them. The English preserves the optative and conditional construction of Socrates’ reply. The wool conducts water; it is not presented as producing wisdom or causing intellectual insight.
