As people who are often involved in rational thought, debate, and posing arguments, and who also strive towards good use of reason, lets learn from our mistakes.
What are some of the irrational ideas you’ve held, or logical fallicies that you’ve made? Especially of interest are ones that are hidden with skillful use of rhetoric.
Obviously you cannot share the stories of ones that are yet undiscovered, but you could talk about the process of self-evaluation or peer-evaluation that led you to realize your fault.
"To make no mistakes is not in the power of man; but from their errors and mistakes the wise and good learn wisdom for the future."
