The first issue can be resolved by arguing for the need to connect a good theory with a thoughtful research program. The second thesis finds its confirmation in that the critique and reconsideration of what was previously established are the essence of scientific investigations. Finally, the issue of the role played by values in developmental psychology will be analysed on four levels: the first deals with theories and concepts of values; the second with values as the object of psychological investigations; the third points to how values enter the research process itself; and the fourth refers to how concepts and theories in psychology become filled with axiology.
