![]() ![]() ![]() Simple sentences in Propositional Logic are often called proposition constants or, sometimes, logical constants. Compound sentences express logical relationships between the simpler sentences of which they are composed. Simple sentences express simple facts about the world. In Propositional Logic, there are two types of sentences - simple sentences and compound sentences. We conclude with some examples of Propositional Logic in formalizing Natural Language and Digital Circuits. After that, we present a mechanical method for evaluating sentences for a given truth assignment, and we present a mechanical method for finding truth assignments that satisfy sentences. We then introduce the notion of a truth assignment and use it to define the meaning of Propositional Logic sentences. ![]() In this chapter, we first look at the syntactic rules that define the language of Propositional Logic. In fact, we might want to say that it is false or that it is true if some other proposition is true. The condition need not be true in order for it to be a proposition. the possibility that it is raining, the possibility that it is cloudy, and so forth. Roughly speaking, a proposition is a possible condition of the world that is either true or false, e.g. The notion of a proposition here cannot be defined precisely. Propositional Logic is concerned with propositions and their interrelationships. Introduction to Logic - Chapter 2 C H A P T E R 2 ![]()
