Descartes

• Descartes maintains that since God made the laws of logic , He could unmake them and so he could create logical impossibilities such as square circles
• "With god all things are possible"- supports this view "I do not think that we should ever say of anything that it cannot be brought about by God".
• what is the problem with the Cartesian view of omnipotence?

  for Christians, there is scriptural evidence against the view. The Bible teaches that God cannot lie or swear by a being higher than himself.
• what is the second problem with the Cartesian view of omnipotence?

  since this view of omnipotence implies that God can create a square circle, this view implies a self-contradiction.
• Why do many philosophers reject the Cartesian view of omnipotence?

  many philosophers would reject the Cartesian view of omnipotence on the grounds that this view implies an absurdity. For example, if our assumptions about our financial position lead us to conclude that we'll go broke by next Tuesday and also we won't go broke by next Tuesday, then obviously there's a problem with some of our assumptions. 
• how would defenders of Cartesian omnipotence respond?

  Defenders of Cartesian omnipotence may rightly respond that such a criticism merely assumes the reliability of principles of reasoning that Descartes's argument has called into question.
• The difficulty of understanding is compounded when we're told that God can become bad and simultaneously be completely good, that He can even cease to exist while at the same time continuing to exist.
• it's hard to make sense of a God to whom the principle of non-contradiction does not apply. What would such a God be like? As we cannot say how a non-logical world would look, we cannot say how a supra-logical God would act or how he could communicate anything to us by way of revelation.
