Greater understanding of the term craft has given me further insight to the four fundamental categories (PACS) to which all human activity can be classified. The stipulative definition of craft is defined as being a skill or technique in handling the physical world, tending to be practical. It is a kind of "body knowledge" where physicality is being increased in its aim to produce something. The mind is no longer engaged for the simple fact that since the action has occurred so many times, the body is functioning from muscle memory. Thus, it is the engagement in the acivity that makes it craft. Furthermore, art is the source of craft. There is a technical aspect that has to be overcome in order to get art to the point where it can be carried out through craft.
In the larger scheme of things, Philosophy develops questions that lead to experimentation, and the experiments produce information about the world to which techniques are then formed. In short, Philosophy and Art are interior and mental in their nature, where as Craft and Science appear to be exterior, making them physical. However, what Philosophy shares with Science is that the centality of both is theory. Philosophy is theoretical, but in Science, theory is tested.

Philosophy - aims to determine truth (reflection)
Art - aims to produce something where the purpose is not the thing produced, but the expression carried by the the thing (inspiration and expression)
Craft - aims to produce something (doing production)
Science - aims to determine fact (investigation/testing/observing/using the senses)

P - mental
A - mental
C - physical
S - physical
