Cornelius Van Til

Reformed theologian; origin of the presuppositional method TAG inherits

Van Til (1895–1987) argued that no fact is intelligible outside the Christian framework, and that apologetics should therefore proceed by internal critique: grant the unbeliever's position for the sake of argument and show that on its own terms it destroys the possibility of knowledge.

His method is the ancestor of nearly every transcendental argument Debby maps, including formulations offered by people who would reject his Reformed theology outright. That inheritance matters: an objection that lands on Van Til's version does not automatically land on a later one, and a strength of the later version cannot be borrowed back without argument.

Why Debby cites them

Same-corpus is not same-argument. Debby tracks the lineage explicitly so that a Van Tillian premise is never quietly substituted for a contemporary one, or refuted in its place.

What Debby has mapped

What Debby has not settled

Every person page carries this block, including for positions Debby shares. A page without it would be advocacy.

  • Whether the Reformed doctrinal commitments Van Til's version depends on are separable from the transcendental machinery, or whether an Orthodox formulation inherits load-bearing premises it does not actually hold.
  • Whether the 'no fact is intelligible outside the Christian framework' claim is a transcendental necessity, a theological postulate, or an equivocation between the two. Debby has not adjudicated this.
  • Debby has not yet done a primary-source pass on Van Til's own corpus; the lineage claim rests on secondary characterisation and is marked as such.
