You: How can you say that marijuana is evil and fasting, good?

Aaron: Drugs deceive the mind into believing things which are not true; they are the tools of Satan.

You: If you are saying that those experiences which produce visions in keeping with your philosophy — visions of God and such — are good while those which produce visions counter or neutral to your philosophy are bad, then you are not going to convince me with this argument. Unless you can show me that delusions during fasting are somehow superior in truth to those during drug use, then I have no reason to believe that there is revealed truth in either.

Aaron: I see how you have trapped me by turning the conversation to fasting, but my main point remains. Visions of God can be had during prayer or baptism, nothing else is necessary. That is how I know that these visions are true.

You: Nonsense. A child might be sure that he has seen a monster in his room, or I might have a feeling that someone is watching me, but neither of these proves anything. The human mind is too easily deceived for something as simple as a physical response to an emotional situation — such as prayer or being "born again" — to mean anything.
