Abstract

The relation between theory and practice is the object of a central debate in the history of science. In a recent contribution to the issue, L. E. Sandelands equates practice with G. Ryle's "knowing how" and theory with Ryle's "knowing that," arguing that practice and theory are incommensurate forms of knowing such that theory cannot be translated into practice. R. T. Craig took issue with Sandelands' position, pointing out that it reflects an academic approach removed from everyday social behavior in which problem solving is always both practical and theoretical. The authors agree and take this blurring of the theory/practice dichotomy as a cue to deconstruct the conception of two ways of knowing. J. Shotter's concepts of "joint action" and "knowing from within" suggest a third type of knowing which develops between knowers in particular contexts or circumstances. This third way of knowing has important implications for psychological training and inquiry. 2012 APA, all rights reserved)
