Spanish clergy relinquished at once, not other literature, but the most elementary knowledge, for the sake of studying Arabic and Chaldee books? And this is not alleged to have been for the purpose of converting Moors and Jews, but as a literary pastime. They are expressly said to have neglected the Scriptures. The object that I had in view was to show the general ignorance of various nations in those ages and this charge of ignorance, as to what lay most open to the Spanish clergy, would hardly be alleviated, even if it were true, that some of them had taken to the study of Arabic. Another criticism in Vol. i., p. 435., relating to what I have said in _Hist. of Literature_, vol. iii. p. 149. (1st edition), concerning Campanella and Adami, is better founded, though your correspondent C. is himself not wholly accurate. I have said of Tobias Adami, that he "dedicated to the philosophers of Germany his own _Prodromus Philosophiæ Instaurandæ_ (Instaur_atio_ is, of course, an error of the press), prefixed to his edition of Campanella's _Compendium de Rerum Naturâ_, published at Frankfort in 1617." C. says, "This _Prodromus_ is a treatise of Campanella's, not, as Mr. Hallam says, of Adami. Adami published the _Prodromus_ for Campanella, who was in prison; and he wrote a preface, in which he gives a list of other writings of Campanella, which he proposes to publish afterwards. What Mr. Hallam calls an edition, was the first publication." The words _Prodromus Philosophiæ Instaurandæ_, which appear only on the title-page, are of Adami himself, not of Campanella. The work of the latter is called _Compendium de Rerum Naturâ_, and is printed, after the preface, with this running title. The error into which I fell was to refer the words _Prodromus Philosophiæ Instaurandæ_ to the preface of Adami, and not to the entire work. It may be satisfactory to give the title-page, and one or two extracts from the preface:-- "Prodromus Philosophiæ Instaurandæ, id est, Dissertationis de Natura rerum Compendium, secundum sera principia, ex scriptis Thomæ Campanellæ præmissum, cum præfatione ad philosophos Germaniæ. Francofurt. 1617." _Prodromus_, of course, means the _avant-courier_ of a new philosophy; and this, I might think, was intended for Adami himself. But, on looking again at the preface, I perceive that it refers to the _Compendium_, which was to lead the way to ulterior publications. "Præmittere autem hoc saltem opusculum visum nobis est, quo brevis ἀνακεφαλαίωσις physicorum philosophematum conjecta est, ut judicia doctorum ex eo in Germania experiremur, exercitaremusque. Cui si operæ pretium videbitur, subjungemus posthac autoris pleniorem et concinniorem Epilogismum Philosophiæ Naturalis, Moralis et Politicæ, addito opusculo Civitatis Solis, quo idea ingeniosissima reipublicæ philosophiæ secundum naturam instituendæ proponitur."
