This is from the book A History of Western Philosophy. This particular paragraph was a quote from Eduard Zeller and is a criticism of Aristotles philosophy regarding the world.
Any help will be appreciated.
In a nutshell, Zeller's is criticizing Aristotle for not being enough empirist.
Eduard Zeller was a neo-kantian; see the last statement:
"ideas ... removed from experience ... and transformed from a logical product of human thought into ... a supersensible world".
