Horace-Benedict de Saussure Professions : Physicist Born : February 17, 1740 Died : January 22, 1799 Browse All Authors Famous Quotes by Horace-Benedict de Saussure The theory of the earth is the science which describes and explains changes that the terrestrial globe has undergone from its beginning until today, and which allows the prediction of those it shall undergo in the future. The only way to understand these changes and their causes is to study the present-day state of the globe in order to gradually reconstruct its earlier stages, and to develop probable hypotheses on its future state. Therefore, the present state of the earth is the only solid base on which the theory can rely.
