The connection between knowledge and action can be examined empirically in two ways: the first by studying the relationship that knowledge has to action and the second by examining the connection between action and knowledge. Without trying to include the whole span of the problems involved in this double link, this article attempts to sketch some aspects of the impact which action claims to have upon knowledge by examining certain practices which emerge in an explicit way from such a connection. Set in the context of Canada and Quebec, the examination focusses chiefly on some governmental reforms which try to establish explicit functions of control, coordination, and planning. The theme of these reforms exhibits the desire on the part of these governments to stress the deliberate, accountable, and rational nature of the decisions. It seems to be a question of a new compulsion to want to break with the opportunism of the past and to reestablish the links between the “scholar” and the “politician.” In this situation how well do the reforms come out? Is there a real connection with knowledge or is it alluded to only to justify the political pronouncement? These are the questions on which the author tries to shed some light.
