By developing a new ontological argument for the existence of God, Joshua R. Sijuwade presents an innovative approach that enriches the existing discourse with fresh insights and a contemporary perspective.

The ontological argument seeks to demonstrate the existence of God from an a priori standpoint and Sijuwade begins by addressing the substantial critique the modal argument has received. He embarks on a rigorous exploration, providing needed analysis and a positive iteration termed the 'Rational Ontological Argument', rooted in a novel modal methodology known as Rational Modal Realism.

Using this new method, Sijuwade focuses on demonstrating how the central concepts and theories within modal metaphysics and epistemology-such as modal realism, modal rationalism, trope theory and ontological pluralism-offer a means to develop a victorious ontological argument.

Employing contemporary analytic methods and suggesting productive directions for further research, Sijuwade makes a key contribution to philosophy of religion and re-invigorates the age-old philosophical argument for the existence of God.
