typologies of scepticism

I have been reading about coinherence recently, as my new postdoctoral fellowship in theology and science is taking up the idea and practice of coinherence as a model for scholarship in this area of study and public discourse. As such, I stumbled upon G. B. Verity's Life in Christ: A Study in Coinherence (London: Longman, Green and Co., 1954), in which he writes the following that captured my interest:

'Every man,' says T.S. Eliot, writing on the Pensees of Pascal in Essays Ancient and Modern, 'who thinks and lives by thought must have his own scepticism.' But there are two kinds of scepticism: one produces wanton, unreasonable disbelief and ends in a dogmatism of denial; the other is the spirit of lively enquiry which is opposed, not to belief as such but always to excessive dogmatism, whether of affirmation or denial.
