Need to have good working knowledge of Fechners work and how some of it related to the development of Psychology as a line of scientific investigation.

• Focus on his work on psychophysics and how he taught us that we could quantify aspects of the minds.
• Western philosophy (inc. science and mathematics) had been struggling and disagreeing about the nature of our material and spiritual form.
• Fechner offered a useful set of tools and possibilities to not only conceive of, but mathematically measure aspects of human consciousness.
• Could and would psychology have been able to develop without this important steppingstone? Was it all Zeitgeist or was Fechner needed?
