What is a theory of something? What does a theory aim to do? The word theory comes from Greek and originally meant something like a way to look at things, a point of view. A theory is basically an idea, usually centred within one specific worldview, or a philosophical idea, about the nature of a given aspect of the world. Depending on the basic ideas that we bring into the experience of any event, we influence and, to some extent, limit, or narrow down, our field of enquiry. Humans are naturally curious and like to hypothesize about the world. Most academics believe that creating hypotheses and testing them can further our understanding of the world we inhabit. This is in itself already only relatively true; it holds within one specific worldview, the ‘scientific method’, influenced by Western philosophy since the time of Socrates. In Buddhist philosophy, for example, rational enquiry reveals nothing about the true nature of existence because it can only touch on superficial, illusionary aspects of reality. Real knowledge in Buddhism can only come through introspective meditation (and in Greek, ‘theory’ could indeed also refer to ‘contemplation’).
