Our language may be capable of receiving and assimilating all the riches of other languages; but so long as such an assimilation is in abeyance, the language remains poor and imperfect, nay, it continues to "deteriorate, as does everything else, in the hands of Protestants and unbelieving Englishmen and Americans." We still need many philosophical words. I have given a few examples of such a need in the preceding pages. That we also need a number of new phrases is undeniable; but I will not enter into the discussion of so difficult a subject. I prefer simply to mention a few Latin phrases, which are much used by Catholic philosophers or theologians, and will allow the reader himself to attempt their translation without altering their philosophical meaning, and without infringing upon English usages. Translate: _Actus et potentia conspirant in unitatem essentiæ._ _Actio motiva terminatur materialiter ad mobile, et formaliter ad motum._ _Sicut se habet actus substantialis ad esse simpliciter, ita se habet actus accidentalis ad esse secundum quid._ _Facultas ordinatur ad operationem ut actus primus ad secundum._ _Quidquid sistit in suis essentialibus, nullo superaddito, est unum per se._ _Intellectus attingit objectum sub ratione veri, voluntas autem sub ratione boni._ _Actus et potentia principiant ens principiatione metaphysica._ _Relatio est id cuius totum esse est ad aliud se habere._ _Motus est actus existentis in potentia ut in potentia._ These and such like phrases will afford matter for a great exercise of patience to him who will undertake to translate them faithfully. _To conspire into unity, to be terminated to a movable object, to be ordered to the operation_, _etc._, are scarcely good English expressions: yet it is not easy to see what other phrases would be calculated to express the same thoughts in an unobjectionable manner. I will conclude by giving the opinion of a competent authority on this very point. The Rev. F. Hill, in the preface to his substantial work lately published under the title of _Elements of Philosophy_, says: "The Latin of the schools, besides being brief, is also peculiarly capable of expressing precisely, clearly, and comprehensively matters which it is difficult to utter through the less accurate vernacular in terms that are neither obscure nor ambiguous." And speaking of the Latin philosophical axioms and sentences, which he inserted in his treatise with their English translation, he remarks: "It was not, however, an easy task, in some instances, to reproduce them with fidelity in the English phraseology, as the classic scholar will readily see from the result." Certainly, the task was not an easy one. Yet the author has most creditably carried out his object. May his example encourage others to cultivate the same field, and thus contribute towards developing "the resources of our noble language," and making it a fit channel for sound philosophical education.
