What is the process that makes purposeful behavior possible?

In the preceding chapters we defined purposeful systems and constructed a set of measures of purposefulness. We have, however, taken for granted those processes that are prerequisite for purposeful behavior. Thus the familiarity, knowledge, and intentions that characterize a purposeful system in a given environment and affect its choice behavior presuppose certain inputs from that environment and previous experience. These are obtained through perception and consciousness of that environment and self, and usually some memory of previous situations. Thus the researcher needs to know of an individual purposeful system not only in its characteristic responses (familiarity), its knowledge and understanding, and its intentions, but also whether and how these are likely to come to play in a given kind of situation.
