“ The Law of Non-contradiction in Aristotle’s Metaphysics: Its Foundation and Formulation”Copula, Vol. XXXI June 2014

Abstract: The Law of Non-contradiction is one of the certain principles of thought in Aristotle’s Metaphysics. By distinguishing between science and metaphysics, he outlines the nature of metaphysics and formulates the fundamental principles of metaphysics, the science of being qua being. This distinction of science and metaphysics sets the foundation for The Law of Non-contradiction as well. In this paper, the LNC has been discussed in the light of three questions: in terms of nature, ‘how is the LNC formulated in Aristotle’s Metaphysics?’; in terms of importance, ‘why is it necessary to formulate the LNC?’ and; in terms of evaluation, ‘what is the consequences of denying the LNC?’.


“Possible Worlds” Copula, Journal of the Philosophy Department, Jahangirnagar University. Vol. XXVIII June 2011, pp.69-74, ISSN No. 1563-0692

The modal realism about possible worlds of David Lewis has been critically analyzed by Robert C. Stalnaker by finding out four more basic theses in it.  On the basis of one of the theses Stalnaker renders David Lewis’ doctrine as an extreme realism whereas he ignores Lewis’ metaphysical approaches as well as its influence on the whole doctrine. Moreover, Robert Merrihew Adams’ view of reducing possible worlds to propositions is sufficient to entitle Lewis’ doctrine as an extreme realism as well; hence, Stalnaker’s analysis seems redundant. The purpose of the paper is to emphasize David Lewis’ perspective towards metaphysics and to show that Stalnaker’s proposed view of moderate realism adds nothing new to the possible worlds semantics.
