In his diary, “Menschen und Dinge,” 1885 (page 29), _Schoenbein_ writes: “There are still people who fancy in their limited mind that, the deeper the human intellect penetrates the secrets of nature, the more extensive its knowledge, the wider its conception of the exterior world, the more it must forget the cause of all things. Many have gone even so far as to assert that natural science must lead to the denial of God. This view is without all foundation. He, who contemplates with open eyes, daily and hourly, the doings and workings of nature, will not only believe, but will actually perceive, and be firmly convinced, that there is not the smallest place in space where the divine does not reveal itself in the most magnificent and admirable way.” And in a similar strain _Liebig_ writes: “Indeed, the greatness and infinite wisdom of the Creator of the world can be realized only by him who endeavours to understand His ideas as laid down in that immense book,—nature, in comparison to which everything that men otherwise know and tell of Him, appears like empty talk” (Die Chemie in ihrer Anwendung). Now let us turn to the geographers. We merely mention _Ritter_ (died 1859), the man who raised geography to the dignity of a science; he was a faithful Protestant, while biassed against the Catholic Church. In spite of this, a Catholic historian, _J. Janssen_, has sketched his life, in which we read: “Firm in his belief in the living God, and in the Incarnate Son of God, His Redeemer, he furnishes a clear and convincing proof that this faith, far from being a contradiction to natural science ... alone enables man to acquire an extensive and deep knowledge of nature.” We give only passing notice to the founder of scientific crystallography, _R. Hauy_ (died 1822), who was a dutiful Catholic priest. The geologists now will get a hearing.
