Previous: Chapter 12: Objectivity
Honesty is the essence of objectivity in a social context.
Honesty is my recognition that you too are a thinking being, that you too have the same cognitive relationship to the world that I do, that you too have the same desire to know that I do, that both of us are focused on the same reality and thus will likely come to similar conclusions if you and I both use our powers of thought.
My honesty enables you to be more objective. Your honesty enables me to be more objective. Indeed, my honesty also enables me to be more objective, because it instills in me a habit of truthfulness. By being honest with each other, you and I build a shared commitment to recognizing reality and sustain a shared culture of achieving objectivity.
