|A 1902 review of George Gore's "materialistic morality", which defines morals based on truth, as determined scientifically, i.e. as based on evidence, and the experimental method. |
In 1880, George Gore, in his chapter “The Scientific Basis of Mental and Moral Progress”, outlined some terse notes on scientific based morality; this he later expanded into several books, which by 1902 was being classified as “materialistic morality”. 
The following are related quotes:
“Our experience hitherto seems to teach us that all ‘materialistic morality’, pure as it may otherwise be, operates especially in periods of transformation and transition, as a powerful solvent, while all great and decisive revolutions and reforms first break out in the shape of new ethical ideas.”— Friedrich Lange (1875), The History of Materialism, Volume One
