The relationship between the constants of truth functions and Ordinary language expressions

If language is the symbolic tool by which our thoughts and feelings are expressed so that it is easy to deal with others and achieve communication with them, and if thought cannot appear accurately and clearly, whether in tangible, reasonable or moral reality without relying on exact words and linguistic structures, then we can To say that logic has arisen in the bosom of language and that language is the vessel of thought. If this indicates anything, then it indicates that language and thought are closely interrelated, given that language is the vessel or the external appearance through which thought is presented. As long as it is logic that studies thought in terms of its various forms, then it is natural to associate language with logic.

And if we look now at modern studies in logic and language, we will see that philosophers and logicians pay great attention to language, and then its climax with contemporary philosophers of analysis since “G.Moore” and “B.Russell” and then “L.Wittgenstein” and the philosophers of the Oxford School Contemporaries who do not see in all philosophy except that it is a logical analysis of ordinary language.

Although this clear and close relationship between language and logic, many logicians, led by Strawson, P.F, believe that there is a gap between the laws of each. This gap becomes clear through Strawson's study of the extent of symmetry - or not - between the constants of truth functions and Ordinary language expressions.
