Elementa Philosophica, seu Politica de Cive, id est, de Vita civili & politica prudenter instituenda, Paris 1642 in 4to. Mr. Hobbs printed but a few copies of this book, and revised it afterwards, and made several additions to it, with which improvements it was printed at Amsterdam, under the direction of Monsieur Forbier, who published a French translation of it. Dr. John Bramhall, bishop of Derry in Ireland, in the Preface to his Book entitled a Defence of true Liberty, from an antecedent and extrinsical Necessity, tells us, 'that ten years before he had given Mr. Hobbs about sixty exceptions, one half political, and the other half theological to that book, and every exception justified by a number of reasons, to which he never yet vouchsafed any answer.' Gassendus, in a letter to Sorbiere, tells us, that our author's Book de Cive, deserves to be read by all who would have a deep insight into the subject. Puffendorf observes, that he had been much obliged to Mr. Hobbs, whose hypothesis in this book, though it favours a little of irreligion, is in other respects sufficiently ingenious and sound.
