To be frankly, Stukles, she is kind of right about this specific misinterpretation of what she said.
She did not claimed - otherwise - that she did not need formal skills or anything she may have learnt. Or that any poet needs only this. She just said without her emotions all her formal skills will be not enough for her to write poetry. And she said those emotions are innate.
The reply of Morpheus is just bad.
