Truth-value and its conditions

· Proposition- expresses truth or falsity

· In logic- proposition follows from an argument, e.g. Aristotelian logic, proposition talks about relation of subject with predicate

Subject is p, predicate follows from argument, logic in argument is valid

· Conditions of p being true lie in premises of the argument along and in validity

Conditions like soundness, consistency

· What conditions qualify for ‘true’ – conditionals should be valid for its sense? or truth about p?

E.g bad argument [of unrelated conditionals] vs. good argument [validity+ truth}]

· Sense of proposition - way to refer to an object, establish content as defined

· Sense of proposition allowing/ giving conditions that do not give meaning of subject in proposition

· Therefore determine the conditions required for p being true; then sense of proposition

Therefore knowing ‘black’ and ‘white’ is a pre-requisite, truth-value of a proposition can be understood when sense understood and truth-value be determined when conditions for it are known

· Knowing the truth important- to know its conditions
