Organicism as a doctrine rejects mechanism and reductionism (doctrines that claim that the smallest parts by themselves explain the behavior of larger organized systems of which they are a part). However, organicism also rejects vitalism, the doctrine that there is a vital force different from physical forces that accounts for living things. As Capra puts it, both schools, organicism and vitalism, were born from the quest for getting rid of the Cartesian picture of reality, a view that has been claimed to be the most destructive paradigm nowadays, from science to politics.
