PAC&S and human action

I feel as if all human action can be described through some combination of philosophy, art, craft, and science. This is a sufficient means by which to understand all factors of human activity. Philosophy covers the mental "inner world". This is a constant study of a one's thoughts, emotions, or beliefs. Philosophy can never fully be explained, there for no one can understand human action without it. Art is a way in which one can express them the best way they know how. Some represent themselves through music, some through painting drawing or sculpture, and some through writing and theater. Craft is needed in a means in which we need to live; craft is needed in the construction of practical useful tools, as well as technology which we utilize everyday to assure the safety and precision of our society. Science is needed to help prevent sickness, to learn about the past, to help fight crime, as well as many other helpful actions which are used daily. Science is an observation, identification, description, and experimental investigation. With out some combination of these four elements it would be difficult for one to communicate with their surroundings.
