composed of intuitions and is the source of intuitions,--the _Deus in nobis_ of Giordano Bruno. 'It is evident,' he continues, 'that Nature is originally identical with that which in us is recognized as the subject and the object.' Thus the empirical school, in its representative, Aristotle, met in the martyr of Nola an opponent vigilant, earnest, powerful. And while the legitimate prosecution of the former mode of philosophizing has led to deism, skepticism, atheism, and materialism, it is to those who have retained in methods, more mathematically clear and more perfectly developed than that which Bruno disseminated, but still bearing, as their key-note, the one great idea of his bold crusade,--to those we must look for all that is most pure, most noble, in Philosophy: a system or succession of systems whose primitive idea--substance and essence--is the very God for a supposed denial of whom Bruno died. '_Cosi vince Goffredo!_' Thus rolled on the centuries. Germany, France, England, and Scotland had each contributed her knights to the great tournament of Mind. And now the first symptoms of agitation appeared on the hitherto unruffled surface of Thought in the New World. Still panting after her victories, scarcely used to her new freedom, at first the presence of a power antagonistic to the orthodox faith was unsuspected even by those who first entertained it. But the stone had been dashed into the tranquil ocean when the May-flower was moored on the New England coast, and its circling eddies drew curve after curve among the descendants, brave, conscientious, energetic, of the old Puritans. The stern Calvinism, by which their fathers had lived and died, was, by these early recreants, first mistrusted, then questioned, and finally abjured. The murmurs of dissent that had long agitated the sturdy upholders of the accepted faith, broke out in a demand for a system whose claims should be less absolute, and whose nature should satisfy those fugitive appeals to Reason and the Understanding, that, weak indeed, and faint, were yet distinctly audible to the thinkers of the day. From the cloud of accusation and denial, of suspicion and trial, the new Perseus, Unitarianism,--whilom a nursling of Milton, Locke, and Hartley,--was born, and took its place among the sects, sustained by the few, dreaded and condemned by the many.
