Elie Bertrand (1713-1797) Sees God's Order in Nature's Record: The 1766 Recueil De Divers Traites Sur L'Historie Naturelle

Elie Bertrand (1713-1797) was a Swiss pastor/naturalist whose geological writings are illustrative of the growth of eighteenth-century natural history. Describing, cataloguing, and classifying formed the core of his work, but he also proposed theoretical analyses based on observations in the field. Bertrand's intellectual roots included Cartesian rationalism, British natural theology, and the Linnacan system of classification. Trained as a theologian. Bertrand viewed the physical world as a proving ground for showing God's Wise Design in nature. He was also committed to empiricism, and repeatedly called for expanding the base of geological knowledge.

Several of the published products of Bertrand's attempts to understand the natural world were brought together in the 1766 Recueil de divers traités sur l'histoire naturelle. By briefly considering each of the incorporated papers, it is possible to recognize the topics which interested eighteenth-century naturalists and to develop insight into the methodologies they used. In the Recueil we see Bertrand's eclectic epistemology attempt to deal with such topics as the interior of the earth, earthquakes, fossils, and the origin and Providential use of mountains.

Celebrated in his day, Bertrand was a correspondent of Voltaire, a counselor to the Polish court, and a member of numerous learned societies. He published articles in the French Encyclopédic, and his 1763 Dictionnaire universal des fossiles was among the most-read scientific books of the century. The obscurity which enveloped Elie Bertrand seems related in large part to the fact that he was an accumulator of data and a commentator about past theories, rather than an innovator of new concepts. As the natural theology that undergirded his writing became obsolete, the cogency of his arguments diminished. In the context of his time, however, Bertrand is an instructive example of how geoscience matured during what has been termed a sterile period in the development of natural history.
