Nassim Taleb on opinions vs. actions

Never ask anyone for their opinion, forecast, or recommendation.  Just ask them what they have - or don't have - in their portfolio.

~ Nassim Taleb

Robert Higgs on opinions and ideology

To embrace ideology is to join a community of like-minded people. “Opinions,” a political scientist has written, “are the invisible membership cards of society. They tell us who is like us and who may be against us. Opinions held in common are powerful bonds.”

~ Robert Higgs, Crisis and Leviathan

Phil Duffy on the pursuit of truth

We're all entitled to our own opinions.  We're not entitled to our own facts.

~ Philip Duffy

(This is not an original quote, but one borrowed, perhaps here: “Everyone is entitled to his own opinion, but not to his own facts."  ~ Daniel Patrick Moynihan)
