This chapter seeks to clarify the notion of intention by addressing the question of whether intention requires a belief that one will succeed. It argues that the question has traditionally been badly posed, framed as it is in terms of all-out belief. We need instead to ask about the relation between intention and partial belief. An account of partial belief that is more psychologically realistic than the standard credence account is developed in this chapter. A notion of partial intention is then developed in turn, standing to all-out intention much as partial belief stands to all-out belief. Various coherence constraints on the notion are explored. The chapter concludes that the primary relations between intention and belief should be understood as normative and not essential.
