I heard some wisdom last week that got me thinking. It’s more important to listen to people who disagree with you rather than those that constantly agree.
These folks will never encourage you to examine your beliefs for accuracy and diminishes any feedback of idiotic ideas. Those who disagree with you help illuminate the validity of your belief system by enabling a discarding of notions that fall apart under a different light.
In turn constructive disagreement propels those involved towards knowledge, incrementally driving each other to wisdom.
