In Logic, an argument is a set of declarative sentences (statements) known as the premises, and another declarative sentence (statement) known as the conclusion in which it is asserted that the truth of the conclusion follows from (is entailed by) the premisses. Such an argument may or may not be valid. Note: in Logic declarative sentences (statements) are either true or false (not valid or invalid); arguments are valid or invalid (not true or false). Many authors in Logic now use the term 'sentence' to mean a declarative sentence rather than 'statement' or 'proposition' to avoid certain philosophical implications of these last two terms.
