Before engaging in a debate with an educated or intellectual opponent, there are a few questions you should consider asking:
1. Is knowledge accessible to someone without his degree/level of education?
2. Is knowledge accessible to persons of other faith or to persons of no faith? (If the opponent is religious.)
3. What would cause him to change his mind about his beliefs or ideas?
The answers to these questions will help you to know if discussion will be productive. If the answer to the first or second question is “no,” conversation will be futile if you do not hold the same title or degree as your opponent. He will attempt to teach you, but will not be open to a meaningful exchange of ideas.
If he does not provide at least one concrete, testable answer to the third question, conversation will be futile. A reasonable person will allow his mind to be changed by facts and truth. An ideologue will maintain his belief in spite of evidence to the contrary.
The third question is equally useful when beginning a dialog with an uneducated opponent. Discussion is meaningless unless each party recognizes the possibility of error and is willing to alter his position to fit the facts.
Finally, you should answer each question above for yourself. Do your answers reveal you to be a seeker of truth or an ideologue?
