τὰ δὲ ἀγαθὰ καλά. For the coincidence
of these two concepts, cp. Prot. 360
B, Hipp. Maj. 297 B, C, Phileb. 64 E ff. It might be near the truth to say that
τὸ καλόν is neither less nor more than τὸ ἀγαθὸν in its external aspect,
“goodness” as apprehended by the aesthetic faculty, or goodness
qua attractive and soul-stirring. See also Plotin. de pulcr. p. 46; Procl. in I Alc. p. 329.
Ἐγώ...σοὶ...σὺ. The personal pronouns are, by position and repetition, emphatic. Agathon means to imply that he yields not so much to the force of argument as to the wordplay of Socrates' invincible dialectic: cp. 216 B below: Xen. Symp. V. 8.
