Abstract

"Wherever possible," said Bertrand Russell, "substitute constructions out of known entities for inferences to unknown entities." Metaphysics in this style is the activity of formulating and applying a calculus. We are to supply a list of primitive ideas, with a specification of the rules for combining them, and a sample of complexes created by combining these simples. Every obscure idea is to be reformulated as the complex deriving from these simples. The values impelling us include economy, clarity, decidability, and fruitfulness.
