Abstract

According to Gilbert Ryle, improvisation is a basic feature of ordinary action. In this paper, we take this idea seriously. Action is improvisation, in that it is situated: It is shaped by attentive responses to environmental circumstances. This is a crucial aspect of agency. However, it is neglected by causal theories of action (Bratman; Mele) and only partially addressed by Thompson’s process-oriented theory. By resorting to Kant’s theory of judgment, we argue for understanding action performance in terms of improvisational shaping of action in situ. The focus on improvisation points to a situated kind of practical rationality entailing the reciprocal shaping of intention and action instead of the ordinary instrumental kind of rationality of action as unidirectionally determined by intention.
