Philosophical basis for decision and action understanding are presented at this paper. Two different theoretical approaches are investigated. One of them explore the differences between Weber and Habermas propositions about human action. The other one presents remarks about decision process concept since Simon. The purpose of the article is to underline that both approaches shows a similar change on action and decision conceptions. The rational action and decision conception gives place to a social constructed action conception. The rational actor view gives place to a self constitution based on networks of sense view.
