The church does not object to the study of the natural or physical sciences, nor to the accumulation of material wealth; but she does object to making the initial order the teleological, and to the cultivation of the sciences or study of the physical laws for their own sake; for, with her, not knowledge but wisdom is the principal thing. She requires the physical and psychological sciences to be cultivated for the sake of the ultimate end of man, and in subordination to the Christian law which that end prescribes. So of material wealth; she does not censure its production, its exchange, or its accumulation, if honestly done, and in subordination to the end for which man is created. What she demands of us is that we conform to the Creator's plan, and esteem things according to their true order and place in that plan. She tolerates no falsehood in thought, word, or deed. The natural is not suppressed or injured by being subordinated to the supernatural, for it can be fulfilled only in the supernatural. We find the indications of this in nature herself. There are, indeed, theologians who talk of a natural beatitude; but whether possible or not, God has not so made us that we can find our beatitude in nature; that is, in the creature or a created good. He has made us for himself, and the soul can be satisfied with nothing less. This is the great fact elaborated by Father Hecker in his _Questions of the Soul_, and his _Aspirations of Nature_. In the first work, he shows that the soul asks questions which nature cannot answer, but which are answered in the supernatural; in the second, he shows that nature desires, craves, aspires to, and has a capacity for, the supernatural; that the soul is conscious of wants which only the supernatural can fill. Man has, as St. Thomas teaches, a natural desire to see God in the beatific vision; that is, to see him as he is in himself; to be like him, to partake of his divine nature, to possess him, and be filled with him. This alone can satisfy the soul, and hence holy Job says, "I shall be satisfied when I awake in thy likeness."
