26 August 2006 SPECIAL POSTING NOTICE John Theodore Merz, History of European Thought in the Nineteenth Century is now available for viewing. This is a very readable account of the progress of science and philosophy during the century, written just prior to the major scientific and cultural events of the Twentieth century. I find his narrative fascinating for two very different reasons: first, for the insight that he provides on the interactions of science in England, France and Germany in the Nineteenth century; and second, for the total absence of any insight or foreview into the cataclysm soon to follow -- in which secular forces, inspired by just the science and philosophy that he opened up so well, destroyed many times more lives and ways of life than all of the (regretable) religious wars and pogroms in all of history to that time.

The Golden Age of Geology Library is being expanded. Additions will be posted over the next few months. Please pardon the annotations and notes added to the book indices. These are for my personal use -- but of course you can make use of them too, if you please. After I have finished adding the new material, the notes will be organized into a coherent discourse on the development of Geology in the 19th Century. Till then ... feel free to browse. David C. Bossard

The Golden Age of Geology     I confess indeed for my own part, I do not look to see the exertions of the present race of geologists surpassed by any who may succeed them. The great geological theorizers of the past belong to the Fabulous Period of the science ; but I consider the eminent men by whom I am surrounded as the Heroic Age of Geology. They have slain its monsters and cleared its wildernesses; and founded here and there a great metropolis, the queen of future empires. They have exerted combinations of talents, which we cannot hope to see often again exhibited; especially when the condition of the science which produced them is changed. I consider that it is now the destiny of Geology to pass from the heroic to the Historical Period. She can no longer look for supernatural successes: but she is entering upon a career, I trust a long and prosperous one, in which she must carry her vigilance into every province of her territory, and extend her dominion over the earth, till it becomes, far more truly than any before, a universal empire. the Rev. William Whewell delivered February 15, 1839* * Address as President of the Geological Society (England).
