Facts can be useful because the truth helps us to navigate the world better than falsehood, but:
A fact used to argue does not solve a problem.
A fact used to be right does not help anybody.
A fact used to offend will not promote the discussion.
A fact used to distract will not reach intelligent ears.
A fact used to rationalize diminishes one’s character.
A fact used to excuse weakness kills motivation.
Communicating effectively with others and oneself requires more than just speaking the truth.
