Peter Boghossian on The Kalam cosmological argument
Boghossian challenges the Kalam not primarily on its logical structure but on the epistemic reliability of its premises and the unwarranted confidence of its proponents.
Boghossian has engaged the Kalam cosmological argument in numerous discussions and debates, always steering the conversation toward epistemology. His central question is not whether the premises are true but whether the proponent has arrived at belief in those premises through a reliable process. In his experience, belief in the Kalam typically follows rather than precedes belief in God — it is adopted as a justification, not discovered as evidence.
On the premises themselves, Boghossian raises standard objections: we do not know if 'everything that begins to exist has a cause' applies to the universe, since we have no experience of universes beginning to exist. And even if the universe has a cause, the conceptual analysis that identifies the cause as God involves enormous unwarranted leaps. Timeless, spaceless, and immaterial does not entail personal, loving, or trinitarian.
Boghossian is particularly effective at exposing the confidence gap. William Lane Craig presents the Kalam with the certainty of a mathematical proof, but Boghossian argues the premises warrant, at most, tentative acceptance — and the conclusion warrants far less confidence than its proponents typically express. The mismatch between the evidence and the confidence level is, for Boghossian, the real problem.
“An argument that requires you to be certain about things nobody can be certain about is not a good argument. It's a confidence trick.”
