Being efficient when it comes to take the appropriate means for our ends has been regarded as one of the paradigmatic aspects of rationality. Nevertheless, to recognize the normativity of instrumental rationality seems to imply the dubious claim that one must take the relevant means in virtue of having these ends regardless of how irrational or immoral these are. In the following pages I defend a conception of instrumental rationality that allows us to affirm both that instrumental rationality is normative and that there are means one should not take even when he intends the ends for which they are appropriate.
