I've been a book collector for a while now, especially rare books. I don't find it embarrassing, but there are many criticisms of the collector psychology, often coming from collectors themselves. The perception is that collectors are using 'things', and the practice of acquiring these things, to give their lives more purpose -- even if it's apparently frivolous. Collecting supposedly exposes an empty life... and in some cases, that's certainly true. It's still a hell of a lot less destructive than the insulators some use to close up those hollow spots in the human soul -- heroin, joining ISIS, philanthropy.
