If any man is able to convince me and show me that I do not think or act right, I will gladly change; for I seek the truth by which no man was ever injured. But he is injured who abides in his error and ignorance.

I think this quote is complimented well by I and VII (go back and review those if you have a moment). Seeking the truth while understanding that you might yet know the whole truth leaves you open to new experiences, new viewpoints, new understanding. Still, this is not to condone moral relativism. Right and wrong still exist but your understanding of whether something is or is not right may be based on incomplete truths.
