Every month on the month, Less Wrong has a thread where we post Deep Wisdom from the Masters. I saw that nobody did this yet for December for some reason, so I figured I could do it myself.
* 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* "Do not quote yourself." --Tiiba
* Do not quote comments/posts on LW/OB. That's like shooting fish in a barrel. :)
* No more than 5 quotes per person per monthly thread, please.
Arthur Schopenhauer
I hate that quote; it's completely backwards and depends entirely on selection effect.
Many ideas accepted as self-evident, both true and false, are first violently opposed. Many ideas violently opposed are first ridiculed. However, most ridiculed ideas stay ridiculed, and most violently opposed ideas stay violently opposed.
Similarly: If you win, before that they probably fought you. If they fight you, before that they probably laughed at you. And if they laugh at you, before that they probably ignored you.
