Human beings as examples of purposeful systems.

One that can produce (1) the same functional type of outcome in different structural ways in the same structural environment and (2) can produce functionally different outcomes in the same and different structural environments.

Thus a purposeful system is one that can change its goals in constant environmental conditions; it selects goals as well as the means by which to pursue them. It thus displays will. Human beings are the most familiar examples of such systems. (PS 31)
