Famous James Dwight Dana Quotes

“In using the present in order to reveal the past, we assume that the forces in the world are essentially the same through all time; for these forces are based on the very nature of matter, and could not have changed. The ocean has always had its waves, and those waves have always acted in the same manner. Running water on the land has ever had the same power of wear and transportation and mathematical value to its force. The laws of chemistry, heat, electricity, and mechanics have been the same through time. The plan of living structures has been fundamentally one, for the whole series belongs to one system, as much almost as the parts of an animal to the one body; and the relations of life to light and heat, and to the atmosphere, have ever been the same as now.”

If the author has sought to exalt a favorite science, it has been with the desire that man-in whom geological history had its consummation, the prophecies of the successive ages their fulfilment-might better comprehend his own nobility and the true purpose of his existence.”
