Dealing with Foolish Opinions

Russell’s practical advice on dealing with foolish opinions holds as true today as when it was first written. He reminds us to base our beliefs on direct observations whenever possible, be aware of our own biases, seek out opinions different from our own, and be cautious of views that flatter our self-esteem. By following these simple yet effective guidelines, we can minimize our chances of falling prey to erroneous thinking and maintain a more rational outlook on life.

If an opinion contrary to your own makes you angry, that is a sign that you are subconsciously aware of having no good reason for thinking as you do. If some one maintains that two and two are five, or that Iceland is on the equator, you feel pity rather than anger, unless you know so little of arithmetic or geography that his opinion shakes your own contrary conviction. The most savage controversies are those about matters as to which there is no good evidence either way. - Bertrand Russell
