But if we wish to determine the particular fault or error that is peculiar to any one faculty of the human consciousness, it is evident that we must not seek for it in any defective state or imperfect development; but, on the contrary, in the highest and fullest energy. But now an extremely ingenious, clear, and vivid intellect may be combined with what I have lately termed an evil genius--the false power of genius. In such a combination, we have the true state of a perverted understanding, or of that aberration which is peculiar to it, and for which the term of a sophistical intellect seems the tersest and most appropriate designation. And this sophistical understanding is ever the working organ and instrument for the building and construction of all false systems, and to which sooner or later the latter are all obliged to have recourse.
With regard, then, to the co-operation of the sophistical understanding in the formation of philosophical error, and its share and influence on the spirit and the matter of any system of untruth, it furnishes an opposition to the idealistic confusion which the absolute will produces by its predominant idea of the unconditional. Here we have rather a predominating tendency to a realistic view of the world, according to the principle it adopts of the universal insignificance of all things, not merely in reference to morals or practical life, and in the domain of history, but also in nature and the whole creation. And with this view is associated a skeptical contempt for all who dare to think otherwise--all ordinary minds who can not rise to the height where the consciousness of knowing and believing nothing sits enthroned. This tendency, therefore, and this error of the sophistical understanding, is most immediately related to, and associated with, the dialectical confusion of the reason with its endless disputations. But as the absolute volition and pursuit of the unconditional can not well be thought of entirely apart from a certain perversion of the intellectual powers, so the operation of the sophistical understanding is impossible, without a certain admixture of an evil will and an intentional determination to oppose the truth.
