Propositional calculus is a branch of logic. It deals with propositions (which can be true or false) and argument flow. Compound propositions are formed by connecting propositions by logical connectives. The propositions without logical connectives are called atomic propositions.

20 In logic and philosophy, propositional calculus is often intended to symbolize rational deduction. There is something misleading in calling a propositional calculus an axiomatic system and then presenting rules for predicate calculi that don't have axioms. Most or all of the rules here are for natural deduction systems.

In economics, "rational expectations" are model-consistent expectations, in that agents inside the model are assumed to "know the model" and on average take the model's predictions as valid. Rational expectations ensure internal consistency in models involving uncertainty.

We looked to logic for help.

This is the first comprehensive critical evaluation of the use of rational choice explanations in political science. As a result, many tests are so poorly conducted as to be irrelevant to evaluating rational choice models. Tests that are properly conducted either tend to undermine rational choice theories or to lend support for propositions that are banal.

A propositional calculus (or a sentential calculus) is a formal system that represents the materials and the . In particular, when the expressions are interpreted as a logical system, the semantic equivalence is typically intended to be logical equivalence.

A propositional calculus (or a sentential calculus) is a formal system that represents the materials and the principles of propositional logic (or sentential logic). Propositional logic is a domain of formal subject matter that is, up to somorphism, constituted by the structural relationships of mathematical objects called propositions. In this setting, the transformation rules can be used to derive logically equivalent expressions from any given expression.

The preceding papers of this series have examined the properties of an optical calculus which represented each of the separate elements of an optical system by means of a single matrix M. This paper is concerned with th. . This paper is concerned with the properties of matrices, denoted by N, which refer not to the complete element, but only to a given infinitesimal path length within the element. A general introduction is contained in Part I. The definition and general properties of the N-matrices are treated in Part II. Part III contains a detailed discussion of the important special case in which the optical medium is homogeneous, so that N is independent of z; Part III contains in Eq.
