Hitherto deism had been represented by unpublished arguments disingenuously dealt with in published answers; henceforth there slowly grows up a deistic literature. Herbert was a powerful and audacious nobleman, with a weak king; and he could venture on a publication which would have cost an ordinary man dear. Yet even he saw fit to publish in Latin; and he avowed hesitations. [312] The most puzzling thing about it is his declaration that Grotius and the German theologian Tielenus, having read the book in MS., exhorted him "earnestly to print and publish it." It is difficult to believe that they had gathered its substance. Herbert's work has two aspects, a philosophical and a political, and in both it is remarkable. [313] Like the Discours de la Méthode of Descartes, which was to appear thirteen years later, it is inspired by an original determination to get at the rational grounds of conviction; and in Herbert's case the overweening self-esteem which disfigures his Autobiography seems to have been motive force for the production of a book signally recalcitrant to authority. Where Bacon attacks Aristotelianism and the habits of mind it had engendered, Herbert counters the whole conception of revelation in religion. Rejecting tacitly the theological basis of current philosophy, he divides the human mind into four faculties--Natural Instinct, Internal Sense, External Sense, and the Discursive faculty--through one or other of which all our knowledge emerges. Of course, like Descartes, he makes the first the verification of his idea of God, pronouncing that to be primary, independent, and universally entertained, and therefore not lawfully to be disputed (already a contradiction in terms); but, inasmuch as scriptural revelation has no place in the process, the position is conspicuously more advanced than that of Bacon in the De Augmentis, published the year before, and even than that of Locke, sixty years later. On the question of concrete religion Herbert is still more aggressive. His argument [314] is, in brief, that no professed revelation can have a decisive claim to rational acceptance; that none escapes sectarian dispute in its own field; that, as each one misses most of the human race, none seems to be divine; and that human reason can do for morals all that any one of them does. The negative generalities of Montaigne here pass into a positive anti-Christian argument; for Herbert goes on to pronounce the doctrine of forgiveness for faith immoral.
