Sentences and Proposition

Sentences, originally, is a term of grammar and linguistic. Its introduction into logic is a new-made innovation and it still seems strange to many to find the word sentences where propositions capacity have been expected. (Alonzo) Basically, propositions have been taken to be sentences that can be square or false but can never be both. This shows that sentences when they chance upon some conditions pull up stakes become a proposition. One major peculiarity between sentences and propositions is that, a sentence can non be a bearer of virtue value while the proposition does so.This is because propositions have logical connections which modify us to deduce whether it is true or false. Sentences in the kinds of questions, exclamations and the like can not be taken as propositions. Example What is your name? We can not tell whether this is a true or false sentence. A sentence(proposition) will convey truth when it expresses a proposition, that is, when a sentence has a abduce an d it is meaningful.The presence of the reference in a proposition will enable us to connect it with our ideas or beliefs outside our mind in holy order to ascertain their truth value. This differ from a sentence which may not have a reference , example, keep quiet In a proposition like, PHIL 402 students went to Cape Coast last thursday,it is clear what the reference is and with the meaning of the proposition, you can tell whether it is a true assertion or a false one.Thus, propositions and sentences, they have been used interchangeably, but for the philosophers, they are different monetary value referring to different things. Simply, a sentence that has a reference and is meaningful expresses a proposition.
