In this brief summary of the attitude of the Church toward science, it is not possible, and if it were so, it is not needful, to refer in detail to the contributions of the more speculative philosophers, who, although they made no discoveries, advocated those methods of research and directions of inquiry which made the discoveries possible. Among these a prominent name is that of Lord Bacon, whose system of philosophy, known as the Inductive, proceeds from the collection, examination and comparison of any group of connected facts to the relation of them to some general principle. The universal is thus explained by the particular. But the inductive method was no invention of Bacon's; wherever observation or testing of a thing preceded speculation about it, as with his greater namesake, there the Baconian system had its application. Lord Bacon, moreover, undervalued Greek science; he argued against the Copernican theory; and either knew nothing of, or ignored, Harvey's momentous discovery of the circulation of the blood. A more illustrious name than his is that of René Descartes, a man who combined theory with observation; "one who," in Huxley's words, "saw that the discoveries of Galileo meant that the remotest parts of the universe were governed by mechanical laws, while those of Harvey meant that the same laws presided over the operations of that portion of the world which is nearest to us, namely, our own bodily frame." The greatness of this man, a good Catholic, whom the Jesuits charged with Atheism, has no mean tribute in his influence on an equally remarkable man, Benedict Spinoza. Spinoza reduced the Cartesian analysis of phenomena into God, mind and matter to one phenomenon, namely, God, of whom matter and spirit, extension and thought, are but attributes. His short life fell within the longer span of Newton's, whose strange subjection to the theological influences of his age is seen in this immortal interpreter of the laws of the universe wasting his later years on an attempt to interpret unfulfilled prophecy. These and others, as Locke, Leibnitz, Herder, and Schelling, like the great Hebrew leader, had glimpses of a goodly land which they were not themselves to enter. But, perhaps, in the roll of illustrious men to whom prevision came, none have better claim to everlasting remembrance than Immanuel Kant. For in his Theory of the Heavens, published in 1755, he anticipates that hypothesis of the origin of the present universe which, associated with the succeeding names of Laplace and Herschel, has, under corrections furnished by modern physics, common acceptance among us. Then, as shown in the following extract, Kant foresees the theory of the development of life from formless stuff to the highest types: "It is desirable to examine the great domain of organized beings by means of a methodical comparative anatomy, in order to discover whether we may not find in them something resembling a system, and that too in connection with
