With publishing The Philosophy of Tai Chi Chuan I discussed the topic ‘Philosophy’ with a lot of people. I found out, that for many people the difference between ‚philosophy‘ and ‚theory‘ is not 100 % clear. Thus here a try for a definition:
Theory: A theory, in the scientific sense of the word, is an analytic structure designed to explain observations and makes one able to give a prognosis
Philosophy: Philosophy (literally: love of wisdom) is the study of general and fundamental problems concerning matters such as human existence, knowledge, values, reason, mind and so on.
Thus one can say, that theory explains, how Tai Chi Chuan works and philosophy explains why one should do Tai Chi Chuan.
