Note 106 — Chapter III

Lord Macaulay has some pertinent and characteristic remarks concerning this topic in his literary estimate of Dr. Johnson. "How it chanced that a man who reasoned on his premises so ably, should assume his premises so foolishly, is one of the great mysteries of human nature. The same inconsistency may be observed in the schoolmen of the middle ages. Those writers show so much acuteness and force of mind in arguing on their wretched data, that a modern reader is perpetually at a loss to comprehend how such minds came by such data. Not a flaw in the superstructure of the theory which they are rearing escapes their vigilance. Yet they are blind to the obvious unsoundness of the foundation. It is the same with some eminent lawyers. Their legal arguments are intellectual prodigies, abounding with the happiest analogies and the most refined distinctions. The principles of their arbitrary science being once admitted, the statute-book and the reports being once assumed as the foundations of reasoning, these men must be allowed to be perfect masters of logic. But if a question arises as to the postulates on which their whole system rests, if they are called upon to vindicate the fundamental maxims of that system which they have passed their lives in studying, these very men often talk the language of savages or of children." (Essays, Ed. 1852. p. 175.) As to the schoolmen, any one who wishes to form a fair idea of their acuteness with little trouble to himself, may consult the "Synopsis Distinctionum" of H. L. Castanæus, a book found in most learned libraries.
