To articulate a consistent and comprehensive set of basic necessary commitments about reality and knowledge is to articulate a world view. And a world view tests and is tested by the different areas of culture, with their accumulated knowledge, symbol systems, acknowledged possibilities and impossibilities, and areas of discourse. We may speak of this study as the philosophy of culture. All humans are acculturated within a world view, and all humans function within the limits of that world view. We have philosophical commitments, whether we know it or not.
Humans are inescapably philosophical beings.
I contend that philosophy in all of its facets is one integrated discipline. And they in turn are held accountable to, and hold up to account, the philosophy of culture. Therefore, I understand philosophy to be a systematic discipline, not a set of relatively unrelated subdisciplines. To do philosophy well, one must work in many areas of philosophy. Any philosophical conclusion is tested partly by how well its implications work out throughout the discipline.
