with inanimate matter. According to Schumacher many philosophers of science fail to recognize the difference between descriptive and instructional science, or ascribe this difference to stages in the evolution of a specific science, which for these philosophers means that the instructional sciences are seen as being the most advanced variety of science. He is particularly offended by the view that instructional science is the most advanced form of science, because for Schumacher, it is the study of the low hanging fruit of inanimate matter, or less metaphorically the study of the lowest and least complex level of being. As Schumacher sees it, knowledge gained about the higher levels of being, while far harder to get and far less certain, is all the more valuable. He argues that applying the standards and procedures of instructional science to descriptive sciences is erroneous, because in the descriptive fields it is simply not possible to use the experimental techniques of instructional sciences. Experimentation is an appropriate method when dealing with inanimate matter, but applying it to the living world is liable to destroy or damage living things and systems, and is therefore inappropriate. He uses the term scientism because he argues that many people, including some philosophers of science, have misunderstood the theory behind instructional science and instead believe that it produces truth. But the instructional sciences are based on induction; and as David Hume famously points out induction is not the same as truth. Furthermore, according to Schumacher, instructional sciences are primarily concerned only with the parts of truth that are useful for manipulation, i.e. they focus on those instructions which are necessary to reliably produce certain results. For Schumacher, instructional sciences therefore produce theories which are useful: pragmatic truths. By contrast, Schumacher argues that the descriptive sciences are interested in the truth in the wider sense of the word. He argues that materialistic scientism follows a policy of leaving something out if it is in doubt. Consequently, the maps of western science fail to show large 'unorthodox' parts of both theory and practice of science and social science, and reveal a complete disregard for art and many other high level humanistic qualities. Such an approach, Schumacher argues, provides a grey, limited, utilitarian worldview without room for vitally important phenomena like beauty and meaning. He observes that the mere mention of spirituality and spiritual phenomena in academic discussion is seen among scientists as
