Here, however, in front of that ultimate mystery which occurs in all speculation, I must take leave of this singular thinker. In a frequently-quoted passage, Mackintosh speaks of his 'power of subtle argument, perhaps unmatched, certainly unsurpassed amongst men.' The eulogy seems to be rather overstrained, unless we measure subtlety of thought rather by the complexity and elaboration of its embodiment than by the keenness of the thought itself. But that Edwards possessed extraordinary acuteness is as clear as it is singular that so acute a man should have suffered his intellectual activity to be restrained within such narrow fetters. Placed in a different medium, under the same circumstances, for example, as Hume or Kant, he might have developed a system of metaphysics comparable in its effect upon the history of thought to the doctrines of either of those thinkers. He was, one might fancy, formed by nature to be a German professor, and accidentally dropped into the American forests. Far away from the main currents of speculation, ignorant of the conclusions reached by his most cultivated contemporaries, and deriving his intellectual sustenance chiefly from an obsolete theology, with some vague knowledge of the English followers of Locke, his mind never expanded itself freely. Yet, even after making allowance for his secluded life, we are astonished at the powerful grasp which Calvinism, in its expiring age, had laid upon so penetrating an intellect. The framework of dogma was so powerful, that the explosive force of Edwards' speculations, instead of destroying his early principles by its recoil, expended its whole energy along the line in which orthodox opinion was not injured. Most bold speculators, indeed, suffer from a kind of colour-blindness, which conceals from them a whole order of ideas, sufficiently familiar to very inferior minds. Edwards' utter unconsciousness of the aspect which his doctrines would present to anyone who should have passed beyond the charmed circle of orthodox sentiment is, however, more surprising than the similar defect in any thinker of nearly equal acuteness. In the middle of the eighteenth century, he is still in bondage to the dogmas of the Pilgrim Fathers; he is as indifferent to the audacious revolt of the deists and Hume as if the old theological dynasty were still in full vigour; and the fact, whatever else it may prove, proves something for the enduring vitality of the ideas which had found an imperfect expression in Calvinism. Clearing away the crust of ancient superstition, we may still find in Edwards' writings a system of morality as ennobling, and a theory of the universe as elevated, as can be discovered in any theology. That the crust was thick and hard, and often revolting in its composition, is, indeed, undeniable; but the genuine metal is there, no less unmistakably than the refuse.
