"By all means let's be open-minded,
but not so open-minded that our brains drop out."
Richard Dawkins (b. 1941)
Evolutionary biologist and ethologist
Being open-minded doesn't mean that everyone is right, and it doesn't mean that we can't really be sure about right and wrong.
And in some cases it doesn't mean that the other fellow's opinion is as good as yours or mine….it depends on which reasons and which facts the other fellow acknowledges, if any.
But by all means, let's talk about it.
(…and by the way, ethology is the scientific study of animal behavior).
