ABSTRACT
Science can be thought of as activities or as products. An activity may be overt behavior, internal behavior, or some combination. So "activities" encompasses a very wide range of behavior. Putative knowledge is an express or implied answer to a question, stated or unstated. The history of science is filled with a multiplicity of paths taken to generate questions and the activities engaged in pursuit of answers. Throughout the history of the philosophy of science a debate has raged over two contending logics for evaluating theories, a logic of discovery versus a logic of justification. Proponents of the former argue that steps taken in the formulation of a theory are strategic as regards acceptance/rejection. Of the seven dimensions of predictive power, testability is the most difficult to describe and poses the most serious issues/problems, all the more if one takes the philosophy of science seriously.
