Two of the most common objections to the Transcendental Argument for God from both inside and outside of Christianity appear to be inconsistent with each other.
1. TAG is circular.
2. TAG is unstated.
Perhaps the two can be reconciled, but I believe it would take more than the typical surface level treatment of TAG to do so. One notable exception might be when a bare assertion is offered as the proof itself. However it would be odd to describe a mere assertion as “circular”.
