When we read the sections in which Aristotle describes the immense, almost "pure," pleasure that comes along with a life of study, I always ask my students whether or not that is also their experience of study/contemplation. Initially, many of them don't find much congruence between Aristotle's description and their own experience. (This is especially the case if you happen to be teaching the Nic Ethics at the very end of the semester, as I am, when students are stressed out about papers, exams, grades, etc.) But I always ask my students to consider that the reason they no longer find contemplation pleasurable is because they have been habituated to think that way. That is, the structure of the educational system as it is now de-habituates them from just the sort of virtue that Aristotle is describing because we make study/contemplation just a means to some other end, thus taking away both the pleasure and the virtue of it. Students are not really stressed about studying or contemplating, or so I tell them, but rather about the various so-called "ends" to which they believe that activity is directed. So, I ask them to reconsider whether or not contemplation would in fact be pleasurable to them if these conditions were removed.
My experience has been that, when given the opportunity to think about it this way, students actually do like to talk about their love of contemplation. This little thought-experiment also gives them the chance to consider Aristotle's claims at the very end of Book X (in preparation for his Politics) that in order for human beings to really live a happy and virtuous life, they must live in a polis that provides the kinds of structures that encourage its citizens to develop happy and virtuous habits. I ask them: Does the current education system provide that kind of environment? And if it doesn't, what can you do to "decontaminate," so to speak, the environment in which you think from all of those conditions that habituate you to think that contemplation is not pleasurable?
In reference to the conversation we had earlier in the semester regarding "studenting" vs. "learning" (which sparked a great conversation on this blog here and here), I think that Aristotle provides the best kind of interpretive frame. So, I left them with this:
Be a thinker, not a student. You'll be happier.
