 Despite the obvious sophistication of Diderot’s philosophy, his legacy has suffered because of the historical differences separating his writings from the discipline of philosophy as it is practiced today. Enlightenment philosophie was something very different from what professional academic philosophers mean by that term today, and Diderot’s writings are often ignored by modern philosophers because they do not appear to be philosophy as they know it. Like many Enlightenment philosophes, Diderot also worked as an homme de lettres first and foremost, and only as a philosopher narrowly construed in certain instances. He also never authored any recognizable work of “systematic philosophy” if by that term we mean writing in the vein of his contemporaries such as David Hume in his Treatise or Immanuel Kant in his Critiques.
