A Critical Analysis of the Cosmological Arguments

This paper critically examines how far cosmological arguments actually establish the existence and nature of God. Rather than treating the cosmological argument as a single proof, it distinguishes several major families of arguments, including the Kalām Cosmological Argument, Aquinas’s Five Ways, Leibnizian and contemporary arguments from contingency, and arguments from hierarchical dependence and grounding. The central question throughout is not merely whether these arguments point toward some ultimate explanation, but what exactly follows from each stage of the reasoning. Particular attention is therefore given to the transitions from a first cause to a necessary ground, from a necessary ground to Pure Act, and from Pure Act to the further attributes associated with classical theism, such as intellect, omniscience, will, free creation, uniqueness, omnipotence, and moral perfection. The paper also develops an abductive defense of explanatory rationalism. It argues that contingent reality gives us genuine explanatory contrasts and that there are reasons to continue seeking explanations rather than terminating in brute contingency. However, this is defended as a defeasible inference to the best explanation rather than as a deductive Principle of Sufficient Reason. Rationalist infinitism is treated as a stronger rival than brute contingency because it preserves explanation without requiring a final foundation. The conclusion is a position described here as Minimalist Agnostic Deism: a provisional commitment to a necessary ultimate ground of contingent reality, combined with agnosticism about its further nature. The paper argues that cosmological reasoning provides stronger support for necessary grounding than for the full classical conception of God, while leaving open the possibility that further philosophical arguments could justify additional attributes.
