A THOUGHT FOR TODAY:
This habit of forming opinions, and acting upon them without evidence, is one of the most immoral habits of the mind. ... As our opinions are the fathers of our actions, to be indifferent about the evidence of our opinions is to be indifferent about the consequences of our actions. -James Mill, philosopher (6 Apr 1773-1836)
