A Guide for the Perplexed Hardcover â 1977 by E. F. Schumacher (Author). E F Schumacher asserts that it is the task of philosophy to provide a map of life and knowledge which exhibits the most important features of life in their proper prominence. The questions: How am I to conduct my life? What is the nature of art and nature? What is the meaning of religion? are restored to daylight on Schumacher's map of life by his maxim 'if in doubt show it prominently'. Science is therefore restored to its home territory and its growing imperialism over the fields is reserved.
