In this article, I examine Michael Bratman’s account of stability in his planning theory of intention. Future-directed intentions should be stable, or appropriately resistant to change, over time. Bratman claims that the norm of stability governs both intentions and plans. The aim of this article is to critically enrich Bratman’s account of stability by introducing plasticity as an additional norm of planning. I construct plasticity as a kind of stability of intentions which supplements Bratman’s notion of “reasonable stability.” Unlike the (...) latter, plasticity applies mainly to cases in which plan states are abandoned without reconsideration. I focus on the intra-theoretical problems of PTI and elucidate: the distinction between future-directed intentions and plans, the conceptual difference between stability and inertia, which is only implicit in PTI, and the role of the environment of the planner, which has a vestigial role in Bratman’s work. I also defend my incorporation of pl... (shrink)

Planning organizes our actions and conditions our effective-ness. To understand this philosophical hint better, the author investigates and juxtaposes two important accounts in action theory. He discusses the concept of a plan proposed by Tadeusz Kotarbiński in his praxiology (theory of efcient action), and the so called “planning theory of intention” by Michael E. Bratman. The conceptual meeting of these two proposals helps to remove aws in Kotarbiński’s action theory, it also shows the way, in which we can enrich the (...) idea of plans in the frame-work of intentions. Generally, praxiology occurs to be still an important perspective in action theory, which particularly shows how we can improve our understanding of planning when confronted with infuentialcontemporary accounts.
