The paper is a tribute to the late Stuart Hampshire's investigations of the ramifying role of intention in our conceptual scheme.It surveys the central argument of Thought and Action and the third chapter of Freedom of the Individual.Emphasis is placed upon Hampshire's constructive account of human agency and consequent description of the manner in which perception and action are interwoven.His analysis of the character of intentional action, self-knowledge and autonomy is described. Various lacunae in Hampshire's account are identified and an attempt is made to fill them in in a manner consistent with Hampshire's insights.
