Abstract
In this paper I propose to read and understand gestures as logical tools within a synthetic paradigm of knowledge. This interpretation of gesture is drawn from a new pragmatist reading of reasoning in general, and synthetic reasoning in particular. Complete gestures are actions with a beginning and an end that bear a meaning. It is our regular way to embody vague ideas into singular actions with general meaning. The tool is forged by a dense blending of icons, indices, and symbols and by a complexity of phenomenological characteristics as feelings, actual actions, general concepts and habits. The paper illustrates this new way to look at gestures and different kinds of complete and incomplete gestures.
