This document discusses key philosophical concepts related to knowledge creation and research. It defines ontology as concerning what exists in reality, epistemology as how knowledge is acquired and the scope/methods of knowledge, axiology as the nature and ethics of values, and methodology as the principles of knowledge generation. The document notes that a researcher's philosophical perspectives, including their views on these concepts, shape how they approach research questions, design studies, and interpret results. It provides examples of objectivist and constructionist epistemologies and positivist vs. post-positivist paradigms to illustrate how philosophy influences the research process.
