Immanuel Kant 
The Critique of Judgement Part I: Critique of Aesthetic Judgement [EPUB ebook] 

The Critique of Judgment, also known as the third Critique, is a 1790 philosophical work by Immanuel Kant. In it, Kant lays the foundations for modern aesthetics. In this, the first part of the book, the Critique of Aesthetic Judgment, Kant discusses the four possible 'reflective judgments’: the agreeable, the beautiful, the sublime, and the good. He makes it clear that these are the only four possible reflective judgments, as he relates them to the Table of Judgments from the Critique of Pure Reason.
