Is "Transcendental" another word for "Terrible"?

The impossibly-aptly-named theologian Matt Slick has an argument he calls the Transcendental Argument for the existence of God (TAG). The really short version of this is: Logic, therefore God. The argument suffers from a couple of fatal flaws. First, his characterization of logical absolutes leads him to seek a cause or a source where one isn't really necessary. Second, even if we accept his characterization of logical principles, his argument doesn't  really prove what he thinks it can prove.
