What It Means

This is a placeholder explanation generated by the low-overhead model. It interprets "The world is idea. This truth is by no means new. It was implicitly involved in the sceptical reflections from which Descartes started. Berkeley, however, was the first who distinctly enunciated it, and by this he has rendered a permanent service to philosophy, even though the rest of his teaching should not endure. Kant's primary mistake was the neglect of this principle... How early again this truth was recognised by the wise men of India, appearing indeed as the fundamental tenet of the Vedânta philosophy ascribed to Vyasa, is pointed out by Sir William Jones in the last of his essays: "On the philosophy of the Asiatics"..." in the context of "Arthur Schopenhauer, Die Welt als Wille und Vorstellung (1818/19) as quoted in The World as Will and Idea (1883) Tr. R. B. Haldane, J. Kemp p. 4. Schopenhauer cites Jones in Asiatic Researches vol iv. p. 164." to mean that wisdom is timeless.
