CA Without the Principle of Sufficient Reason (PSR)
Two philosophers, Bernard D. Katz and Elmar J. Kremer, have formulated a cosmological argument that does not rely on the Principle of Sufficient Reason (PSR).
Formulation
The argument is based on the Principle of Epistemic Explanations;
given that (i) there is a possible explanation of the fact that
- The proposition that there is a unique necessary being who brought about the existence of everything other than itself by willing that the other beings exist, would, if true, explain why there are contingent beings.
- There is a possible explanation of the fact that there are contingent beings.
- There is no proposition consistent with the claim that there are only contingent beings which, if true, would explain why there are contingent beings.
