As Descartes himself remarked, nothing is too absurd for some philosopher to have said it some time; I once read an article about an Indian school of philosophers who were alleged to maintain that it is only a delusion, which the wise can overcome, that anything exists at all; so perhaps it would not matter all that much that a philosopher is found to defend absolute omnipotence.
