ABSTRACT
This chapter explores on the Es in conducting human inquiry directed toward systemic change. The economy of inquiry becomes paramount, as does its efficiency, effectiveness, and efficacy. The ethics of inquiryand its evaluability pose more complex challenges. The semantic comparisons and contrasts among the Es can be just as confusing as distinguishing. The realization by researchers that there is a nest of constructs to be woven together to propose inquiry is a key insight into research process preliminary to the actual conduct of the inquiry. The kinds of questions that connect human inquiry with praxiology do concern the details required to propose, fund, execute, and report inquiry. The Es form a nexus of methodological interrelations, a conceptual system, that is of great potential value to researchers. The conceptual system brings a means for researchers to provide accountability and validity in disciplined inquiry.
