The Collector’s Fallacy: Why We Gather Things We Don’t Need
Charles Chu

You linked to this quote by A. Edward Newton but didn’t include it inline like you did others that presume something bad is happening with “tsundoku”:

“Even when reading is impossible, the presence of books acquired produces such an ecstasy that the buying of more books than one can read is nothing less than the soul reaching towards infinity … we cherish books even if unread, their mere presence exudes comfort, their ready access reassurance.”

So why all the guilt and hostility over something that gives people pleasure? Where is the virtue in the exercise of discipline if the practitioner doesn’t enjoy it?

By all means do change your behavior as necessary to achieve your goals but first examine your unquestioned assumptions. Or, as David Foster Wallace said:

“This is water.”
