Hi - My question is as follows It is possible for anyone ( alive or dead ) to 1.Make any kind of statement ( including those made in response to this question ) which is not a statement which claims that a. Something is possible ( or impossible ) b.Something is actual ( or not ) c.Something is necessary ( or not) Please note that I am NOT asking about the truth of the statement but only the form in which it is stated - So, for example - A statement which claims that 'Triangles have four sides' ( though false) could be classified as making the claim as a possibiliy, actuality or necessity ( subject to clarification by the maker of the statement ). Also if possible could I have a response to the isues of 'Explanation' what is an 'explanation' - I've often read in textbooks that some author is not offering an 'explanation' but rather a 'description'. Regards - Colin
