Van Till

Bahnsen and Van Till presuppositionalists, for some reason failed to notice that Calvinism is a grand tautological banality. My own theory is that the tautological bafoonism that undergrids Greek philosophy Calving studied and absorbed . This theory needs support

Van Till did not notice that Hegel formulated Meaningless sentences and excatly what  nonsense was absorbed into his philosophy needs further study.  http://en.wikipedia.org/wiki/Tautology_(rhetoric)

Rhetorical tautologies are extremely dangerous because the tautological structure of the argument is indisputable and the conclusion thus a non-sequitur.
