Paul Helm, in the midst of comparing Abraham Kuyper and B.B. Warfield, notes that interesting difference between ideology and value and the way in which sin has a greater effect on ideology.
More, each [Kuyper and Warfield] holds to the differential effect of sin on the mind. In some areas its impact is greater than in others. Its impact is less in the case of formal disciplines, logic and mathematics and greater in those disciplines which involve estimates of value, such as history and literature and most of all, religion and those disciplines adjunct to it, theology in its different departments.
