Dr. Trevor on the Certain MindJohn Owen, Evenings with the Skeptics: Free Discussion on Free thinkers, Vol. II: Christian Skepticism (Longmans, Green & Co: 1881), p. 32.
But in double-truth as in most other forms of mental eccentricity we must take some notice of ‘the personal equation,’ by which I mean the special differences and idiosyncrasies that exist between one man and another in respect of intellectual conformation. There are intellects, e.g. so intensely, I might say morbidly, synthetic, that they insist on acquiring demonstrated certitude at whatever cost. This type of mind must needs set itself to evolve unity from multiplicity, harmony from dissonance, light from a juxtaposition of shadows, without considering how far its self-imposed task is feasible or how far it is in agreement with the constitution of the universe. In the determination to acquire undoubted conviction, no labour is spared and no expense regarded. Subordinate convictions are ruthlessly thrust aside, objections are ignored, disingenuous methods resorted to, in order to obtain and definitively pronounce on certitude… [Dr. Newman’s] processes are irregular, inconsistent, self-contradictory, of impossible application to any other subject than that of mystical dogmatism. His conclusions, on the other hand, are brilliantly clear, vivid, unmistakable. His mental evolution stands forth like a mountain whose summit is lit up by a warm glow of sunshine, while the sides and base are enshrouded in darkness. Minds of this class appear to me dominated by a sort of religious or spiritual ambition which is just as selfish, audacious, unscrupulous, and unpitying as any other kind of ambition. A man who overturns all reasoning processes, who makes a chaos of human methods, who stultifies the lessons of history for the purpose of boasting a light which to his neighbours is only a deceptive ignis fatuus, is not unlike Napoleon, who forced his way through cruelty and bloodshed to attain a crown. Such men forget that the infallibility, the unity, and harmony they have achieved so recklessly suggest to the more cautious spectator division and dissonance. They forget that their shield has two sides, and if certainty is emblazoned on one, doubt is conspicuously legible on the other, and that the real Skepticism of their methods, the profound distrust of human reason which marks them, is only dimly veiled by the vaunted infallibility of their conclusions.
