Abstract

This paper deals with Dooyeweerd's radical thesis, i.e., his thesis that reason necessarily has a 'religious root' (radix = root). This thesis was Dooyeweerd's main justification for his own religious philosophy. First I argue that the arguments Dooyeweerd puts forward do not warrant his radical thesis. Secondly, I argue that Dooyeweerd's thesis itself is ambivalent between the theses (i) that religious commitments form the transcendental conditions for philosophical thinking and (ii) that religious commitments are constitutive for philosophy and (iii) that religious commitments are regulative for philosophy. Each of these interpretations, I argue, is exposed to serious objections and leads to what Vincent Brummer has called 'the dilemma of a Christian philosophy'. I argue that Brummers solution for this dilemma is untenable. Since Dooyeweerd's radical thesis is untenable as it stands, so is his justification of his project of a 'Christian philosophy' ; and since Brummers solution to the dilemma is untenable as well, so is his justification of that project. In the last section of this paper I offer an alternative justification for such a project. The central concept therein is 'properly functioning noetic faculties'
