“Thus you see, he is a Composition of Whim, Affectation, Wickedness, Vanity, and Inquietude, with a very small, if any Ingredient of Madness. … The ruling Qualities abovementioned, together with Ingratitude, Ferocity, and Lying, I need not mention, Eloquence and Invention, form the whole of the Composition.”
- David Hume, in a letter to his friend and fellow Scot, Adam Smith. (H/T, Stephen Hicks).
Hume was writing about JJ Rousseau, whom Hicks has mentioned as one of the most destructive and evil thinkers in recorded history. His other choice for that slot is Martin Heidegger.
