the poor Penia, by definition, by structure has properly speaking nothing to give, except her constitutive lack, aporia… “to give what one does not have” literally written there in the form of the development which starting from there Diotima is going to give to the function of love
Lacan argues that Penia’s structural poverty — her aporia — is the ontological ground of love’s paradox: giving what one does not possess, a formula he reads directly from Symposium 202a and installs at the heart of his theory of transference.
