This html file has been revised from a multi-volume to a single volume file. The Life of Reason, by George Santayana                               15000   [Link: http://www.gutenberg.org/1/5/0/0/0 ]   [Files: 15000-h.htm] The original html file from 2005 contained five subsidiary html files referenced from the main html file. Mobile viewers were unable to handle the external links. A new one volume html file has been produced which allows the PG autogenerated .mobi and .epub files to display the entire work. David
