(Philosophy is) To give a speculative, systematic, complete view of reality; To describe the ultimate, real, nature of reality; To determine the limits, scope, source, nature, validity, and value, of knowledge; The critical inquiry regarding the presuppositions, and claims, made by the different fields of knowledge; and A discipline to get you to "see" what you say and say what you "see."
Science, like art, religion, commerce, warfare, and even sleep, is based on presuppositions. It differs, however, from most other branches of human activity in that not only are the pathways of scientific thought determined by the presuppositions of the scientists but their goals are the testing and revision of old presuppositions and the creation of new.Gregory Bateson
The discussions of every age are filled with the issues on which its leading schools of thought differ. But the general intellectual atmosphere of the time is always determined by the views on which the opposing schools agree. They become the unspoken presuppositions of all thought, and common and unquestioningly accepted foundations on which all discussion proceeds.friedrich hayek
World view, a concept borrowed from cultural anthropology, refers to the culturally dependent, generally subconscious, fundamental organization of the mind. This conceptual organization manifests itself as a set of presuppositions that predispose one to feel, think, and act in predictable patterns.
