Wilde in his best.
The Decay of Lying, a rather short, quasi-Platonic dialogue, is an essay by Oscar Wilde that was included in Intentions, a collection of that sort. It was published in 1891. In it Wilde poses the question of the perfect Art form using man and nature as references.
By reading this essay one cannot avoid asking oneself interesting questions such as: how do we perceive Art, Beauty, Moral, Nature, or what is a good writer that brings those abstract, somewhat ideal, notions into a good literary work.
