an investigation of ‘verity-propositions’ (qadaya haqiqiyyah) of islamic logicians and law-like statements as presented by nelson goodman

the purpose of this article is to present a comparative study of the views of islamic logicians on ‘verity-propositions’ and nelson goodman’s ideas on law-like statements. in order to achieve this, first we describe the analyses of islamic logician of the meaning of factual proposition and goodman`s presentation of law-like statements. then, using a comparative approach, we explain the points of agreement and divergence of these two viewpoints. in this way it will be shown that despite a number of foundational differences, there are many similarities, the systematic investigation of which would have great scholarly importance. these similarities include: universality and possibility of being generalized, the strengthening and confirmation of counterfactual conditionals, and the capacity to give scientific explanation and prediction. as opposed to these similarities, law-like statements are derived from induction while verity-propositions are not so derived.
