Survival is not a matter of being alive this moment and dead the next.
Survival is actually a graduated scale.
This dynamic principle can be subdivided into eight main drive lines, or dynamics, which are held in common with man. This is the effort to survive as an individual, to be an individual. It includes one's own body and one's own mind. It is the effort to attain the highest level of survival for the longest possible time for self. This dynamic includes the individual plus his immediate possessions.
