• Authority — by force or consent
• Opinion — thinks he knows, but not sure he is right
• Ignorance — knows that he does not know
• Teachable — open to know
• Knowledge of — knows and knows why he knows
• Belief — knows the truth and accepts it
• Belief in — believes the truth and embraces it
• Certainty — relational as well as rational
