Abstract

Suppose that you do not do what you have previously decided to do. Are you to be charged with irrationality? A number of otherwise divergent theories of practical rationality hold that by default, you are; there are rational pressures, it is claimed, that favor the long-term stability and eventual execution of distal intentions. The article challenges this view by examining how these purported pressures can be spelled out. Is intention a normative commitment to act? Are intentions reasons for action – or at least for retaining one's intention until the time to act has come? Or is the rationality of ‘doing as you decide’ governed by diachronic wide-scope norms, as Michael Bratman and John Broome suggest? All of these approaches are shown to raise severe problems, which suggests a more modest view: diachronic pressures on intending are at each point in time confined to the very next instant.
