RT Article T1 Engaging Jeffrey Koperski’s decretalism: is occasionalism really avoidable? JF Religious studies VO 62 IS 1 SP 184 OP 196 A1 Muhtaroǧlu, Nazif A1 Malik, Shoaib Ahmed A2 Malik, Shoaib Ahmed LA English YR 2026 UL https://ixtheo.de/Record/1963557921 AB This article critically evaluates Jeffrey Koperski’s decretalism, which presents the laws of nature as divine decrees functioning as constraints rather than dynamic forces. Building on his work, we explore whether his model successfully avoids the implications of occasionalism, as he claims. By analysing his latest publications, we first reconstruct Koperski’s argument and then present three key objections. These include (1) issues related to scientific realism, (2) the principle of simplicity, and (3) the reduction of Koperski’s model to occasionalism. We argue that despite his attempts to distinguish his framework, Koperski’s model ultimately collapses into occasionalism due to the continuous divine sustenance required for natural processes. By engaging with recent developments in metaphysical and scientific debates, this article highlights the limitations of Koperski’s decretalism.
