... Validity can be defined in these terms. An argument A is valid iff there is no evaluation of A’s premises under which they are all true yet A’s conclusion is false. If A’s premises are true, then they impose their truth on the conclusion; or, if A’s premises are true, the move to the conclusion pres ...

Rather, there must be finitely many conventions from which infinitely many a priori truths follow logically. However, this explanation presupposes the apriority of logic rather than explaining it. Since apriori ...
