The "Philosophical Enquiry" is a study of the relationship between strong feelings and forms of art, that considers the inspired persuasiveness of certain kinds of writing alongside experience of the natural landscape, and is gradually being recognized as an important work of aesthetic theory. This eloquent and sometimes erotic book was long considered to be a piece of Burke's juvenilia, published when he was only 28. But it is a precursor of his later political writings, and clearly deals with a fashionable topic of intellectual preoccupation in the 18th-century. This work is also one of the first major works in European literature on the sublime, a subject that was later to fascinate thinkers from Kant and Coleridge in the 18th-century, to contemporary philosophers and literary critics. Adam Phillips has also edited Charles Lamb's "Selected Prose" and Walter Pater's "The Renaissance", as well as writing a study of his own entitled "Winnicott".
