WIKI PROPOSITION
In common philosophical language, a proposition is the content of an assertion, that is, it is true-or-false and defined by the meaning of a particular piece of language. The proposition is independent of the medium of communication.
Since the definition of “proposition” is such a crucial matter to various topics in philosophy, the nature of propositions is highly controversial. Even the existence of propositions is sometimes called into question and, as a result, the term is widely used, even when the term is not itself explicitly defined and therefore confusion, in regard to “meaning”, may arise.
