   Yes I think that I discovered that.   
      
   A deductive argument is said to be valid if   
   and only if it takes a form that makes it   
   impossible for the premises to be true and   
   the conclusion nevertheless to be false.   
   Otherwise, a deductive argument is said to   
   be invalid. https://iep.utm.edu/val-snd/   
      
   This seems to stupidly allow false conclusions   
   to be drawn from false premises and still be   
   considered valid.   
      
   My first incremental change would require   
   a conclusion to be a necessary consequence of   
   all of its premises. I would use the modal   
   logic necessarily operator □ as a binary   
   operator.  H1,..., Hm □ C to adapt Mendelson.   
      
   The next change is much larger. I would use   
   Rudolf Carnap / Richard Montague Meaning   
   Postulates that can mathematically anything   
   that can be expressed in natural language   
   (such as English).   
      
   declarative   
   interrogative   
   imperative   
   exclamatory   
   The entire body of general knowledge would be stored   
   in a knowledge ontology as formalized natural language.   
   https://en.wikipedia.org/wiki/Ontology_(information_science)   
      
   We end up with something like this fully populated with   
   the set of basic facts and the relations between them.   
      
   Kurt Gödel in his 1944 Russell's mathematical logic gave   
   the following definition of the "theory of simple types"   
   in a footnote:   
      
   By the theory of simple types I mean the doctrine   
   which says that the objects of thought (or, in   
   another interpretation, the symbolic expressions)   
   are divided into types, namely: individuals,   
   properties of individuals, relations between   
   individuals, properties of such relations, etc.   
   (with a similar hierarchy for extensions), and   
   that sentences of the form: " a has the property   
   φ ", " b bears the relation R to c ", etc. are   
   meaningless, if a, b, c, R, φ are not of types   
   fitting together. Mixed types (such as classes   
   containing individuals and classes as elements)   
   and therefore also transfinite types (such as   
   the class of all classes of finite types) are   
   excluded. That the theory of simple types suffices   
   for avoiding also the epistemological paradoxes   
   is shown by a closer analysis of these.   
   (Cf. Ramsey 1926 and Tarski 1935, p. 399).".[24]

   Yes I have thoroughly done that, two different ways.   
   Paradox proves that our reasoning is somehow incorrect.   
   One of these ways is similar to Saul Kripke   
      
   https://files.commons.gc.cuny.edu/wp-content/blogs.dir/1358/file   
   /2019/04/Outline-of-a-Theory-of-Truth.pdf   
      
   Here is my way of saying that. Paradox cannot be derived   
   by applying semantic logical entailment on the basis   
   of a complete and finite set of atomic facts.   
      
   Here is the other way the eliminates Paradox of self-reference   
   This short Prolog shows the error of the Liar Paradox   
   ?- LP = not(true(LP)).   
   LP = not(true(LP)).   
   ?- unify_with_occurs_check(LP, not(true(LP))).   
   false.   
      
   This means that the directed graph of the evaluation   
   sequence has a cycle meaning that the evaluation of the   
   Liar Paradox cannot possibly be resolved to a truth   
   value, thus never was a truth bearer or a proposition.   
      
   It expands to this: (and never terminates)   
   not(true(not(true(not(true(not(true(not(true(...))))))))))
