Think you're right? How to test yourself in the battle of ideas.

Our opponents' objections to our ideas often contain insight as to how we can better refine them.

  • When we're convinced in the truth of our ideas, we often believe if we just explain it to others that others will immediately come onboard with them. However, what we see in practice is that we need some resistance from others to help refine those ideas. In doing so, we make them more marketable in the marketplace of ideas.
  • When we have debates, we have to not censor our opponents. We have to be confident enough to have discussions with them aimed at getting at the truth.
  • When we prohibit the expression of ideas, we lose the chance to prove our ideas right — we lose the chance to advance their legitimacy in the court of public opinion.
