Realizing that a plethora of procedures go into the production of what is termed as action, the current endeavour seeks to bring in all the constituents involved in the production of action yet discovered in one fold, showing holistically what action is. As found by many who seek to understand action, one needs a combination of both reductionism and synthesis to understand the phenomenon of action. Forcing us to take a multidisciplinary approach, reductionism allows us to understand the multifaceted nature of human voluntary action. For instance, this exercise of ours goes in to psychology, a subject designed to study human action, to understand some facets of action. Similar facets are studied then from the point of view of neurobiology, a subject that studies nervous system to understand human action. Having found and understood the various components of action, the current paper tries to bring all the components in to one fold under general systems theory, an approach of synthesis. Taking a lead from the foregoing, that is, a holistic understanding of action, the whole exercise moves towards to understand the knowledge framework in which one could fit the understanding of action – a knowledge framework built by causation, reason and purpose.
