You don’t beat a thesis with an antithesis; you beat it with a better thesis. (Jack Kemp, late American politician)
Kemp’s comment would seem to be so helpful in today’s difficult political scene. Instead of always trying to prove the other fellow wrong by a strong opposing argument just offer him a better solution. No one likes to have his position criticized, but he or she may respond well to a better idea with which both can agree.
We use God’s mighty weapons, not worldly weapons, to knock down the strongholds of human reasoning and to destroy false arguments. (2 Corinthians 10:4)
