Reading is not a peripheral philosophical pastime; it constitutes most of what we do when we do philosophy. And the experience of reading philosophy is much more than just a series of interpretative acts: the philosopher-reader is subject to, among other things, sensations, passions, emendations, and transformations. In this essay, I argue that a full account of philosophical reading should outline some of the sociological structures that determine how different communities of philosophers construct such experiences, as well as describe in (...) detail the ways in which philosophers encounter truths while reading. It should, that is, describe ways in which philosophy acts upon readers and the various effects that result. (shrink)
