To begin with, we make certain choices, selecting some goals (the sea voyage) and what appear to us to be the best means to obtain them (the experienced sailors). Next, we need to recognize that it does not follow from just having made a choice that we can implement a given course of action. Our preferred helmsman, for instance, may be sick on that day, or his services may be too expensive for us. Finally, some factors are entirely out of our control and we cannot even begin to influence them, like the direction and intensity of the winds.
