A monthly thread for posting rationality-related quotes you've seen recently (or had stored in your quotesfile for ages).
- Please post all quotes separately, so that they can be voted up/down separately. (If they are strongly related, reply to your own comments. If strongly ordered, then go ahead and post them together.)
- Do not quote yourself.
- Do not quote comments/posts on LW/OB.
- No more than 5 quotes per person per monthly thread, please.
This is my last one for the month, it seems.
"If you would be a real seeker after truth, it is necessary that at least once in your life you doubt, as far as possible, all things." - Rene Descartes
