This is from Robert Kaplan:
While I have to admit that I derive a certain amount of satisfaction from cataloging a book (or books, as is frequently the case), there is nevertheless something a little depressing about it as well. It is, perhaps, a little like sex: once it’s done, while one (hopefully) feels satisfied, it’s also tinged with a little sadness, as if one were sorry it was over.
I found this quote from Guru's post about A passion for books by Harold Rabinowitz and Rob Kaplan.
My previous post on sex and its analogues is here.
