Oscar Wilde - Arbiter Elegantiae
“Cultivating whatever gave pleasure to my senses was always the chief business of my life; I have never found any occupation more important. Feeling that I was born for the sex opposite mine, I have always loved it and done all that I could to make myself loved by it. I have also been extravagantly fond of good food and irresistibly drawn by anything which could excite curiosity.”
