Abstract

Alvin Plantinga wrote a probabilistic critique of historical arguments for the kernel of Christianity. It is based on the fact that, generally, the more complex a conjunction, the lower its probability. The paper provides elementary insights into the epistemology of Plantinga, probability calculus, and the role of this calculus in contemporary epistemology. It introduces a concept of a good argument, explains in which sense and why, according to Plantinga, no good arguments for Christianity exist, and discusses the following replies. The probability that every argument for Christianity fails can be low. Even if Christianity is less probable than its proper propositional parts, it can be still be probable, whether on the same or on some enhanced body of evidence. Finally, there have been detailed probabilistic arguments for Christianity yielding results significantly different from Plantinga’s cursory estimates.
