Rudolf Hermann Lotze was a German philosopher and logician. He also had a medical degree and was well versed in biology. He argued that if the physical world is governed by mechanical laws and relations, then developments in the universe could be explained as the functioning of a world mind. His medical studies were pioneering works in scientific psychology.
