The Kalam Cosmological Argument

This monograph presents William Lane Craig's influential defense and reconstruction of the kalam cosmological argument for God's existence. Craig revives this medieval Islamic philosophical argument, which had fallen into relative obscurity in Western philosophy, and reformulates it using contemporary philosophical analysis and scientific cosmology. The work represents a significant contribution to natural theology and the philosophy of religion by offering a deductive argument that moves from empirical premises about the universe to the existence of a personal Creator.

Craig structures the argument in a simple syllogism: 1) Whatever begins to exist has a cause; 2) The universe began to exist; 3) Therefore, the universe has a cause. He then argues that this cause must be personal, uncaused, timeless, spaceless, and enormously powerful—properties traditionally attributed to God. The monograph devotes substantial attention to defending each premise through both philosophical argumentation and scientific evidence.

The philosophical defense draws heavily on arguments against actual infinities, particularly examining paradoxes that arise from the concept of an infinite temporal regress. Craig engages with historical figures like Al-Ghazali and contemporary philosophers, demonstrating mastery of both Islamic philosophical traditions and modern analytic philosophy. His treatment of the second premise incorporates Big Bang cosmology and thermodynamic considerations, marking an important integration of contemporary physics into philosophical theology.

Craig's work responds to several philosophical traditions. Against naturalistic philosophers who argue for an eternal universe, he marshals both a priori arguments about the impossibility of actual infinities and empirical evidence from cosmology. Against those who accept the universe's beginning but deny it requires a cause, he defends the causal principle through intuitive appeal and argumentation against uncaused events.

The monograph's significance lies in its role in revitalizing cosmological arguments in contemporary philosophy of religion. Craig's formulation has generated extensive philosophical discussion and debate, influencing both defenders and critics of theistic arguments. His methodological approach, combining rigorous philosophical analysis with scientific findings, established a model for natural theology that engages seriously with contemporary physics while maintaining philosophical sophistication. The work demonstrates how classical theistic arguments can be reformulated and defended using the tools of modern philosophy and science, contributing substantially to debates about God's existence in academic philosophy.
