psychoslice: That would only be true if we all had perfect hearts, being perfect judges of what is true and what is false. A basic premise of reality is that nobody is perfect and whole. When a person gives you true and whole advice you can still cover your heart and reject it.

One who calls oneself a perfect judge must be arrogant. One who says 'I and I alone know what is true and what is best' must be arrogant. That is why it is important to trust a truth that one cannot know.
