- Rincewind is a fictional character appearing in several of the Discworld novels by Terry Pratchett. He is a failed student at the Unseen University for wizards in Ankh-Morpork, and is often described by scholars as “the magical equivalent to the number zero”. He spends most of his time running away from bands of people who want to kill him for various reasons. The fact that he’s still alive and running is explained in that, although he was born with a wizard’s spirit, he has the body of a long-distance sprinter. Rincewind is also renowned for being able to solve minor problems by turning them into major disasters. His unique “skill” is implied to be due to being the chosen one of “The Lady”, the anthropomorphic personification of luck (both good and bad).
- René Descartes (plato.standford.edu)
René Descartes (1596–1650) was a creative mathematician of the first order, an important scientific thinker, and an original metaphysician. During the course of his life, he was a mathematician first, a natural scientist or “natural philosopher” second, and a metaphysician third. In mathematics, he developed the techniques that made possible algebraic (or “analytic”) geometry. In natural philosophy, he can be credited with several achievements: the first to publish the sine law of refraction; developer of an important empirical account of the rainbow; and proposer of a naturalistic account of the formation of the earth and planets (a precursor to the nebular hypothesis, that the planets formed from loose matter orbiting the sun). More importantly, he offered a new vision of the natural world, which shaped modern physics: a world of matter possessing a few fundamental properties and interacting according to a few universal laws. This natural world included an immaterial mind that, in human beings, was directly related to the brain, a position that led to the modern mind–body problem. In metaphysics (the search for the basic principles of everything there is), Descartes provided arguments for the existence of God and to show that the essence of matter is to be spatially extended, and that the essence of mind is thought (where “thought” includes sensory images as well as rational discourse). Descartes claimed early on to possess a special method, which was variously exhibited in mathematics, natural philosophy, and metaphysics, and which came to include, or to be supplemented by, a method of doubt.
