The only artists I have ever known who are personally delightful are bad artists. Good artists simply exist in what they make, and consequently are perfectly uninteresting in what they are. A great poet, a really great poet, is the most unpoetical of all creatures. But inferior poets are absolutely fascinating. The worse their rhymes are, the more picturesque they look. The mere fact of having published a book of second-rate sonnets makes a man quite irresistible. He lives the poetry that he cannot write. The others write the poetry that they dare not realise.
– Oscar Wilde
The Picture of Dorian Gray, Chapter 4. Lord Henry shares his views on artists with Dorian. He believes good artists make for dull people because they give too much of themselves to their art. Bad artists on the other hand are delightful people, they live the poetry they cannot write.
