I accept in a trustworthy manner. So it is not self-justified . But some objections by the skeptic cannot be beaten . They indirectly compete , and are very reasonable in themselves. I saw a zebra, I have a competitor.
People sometimes dream they see zebras.
People never dream they see zebras. Dreams of zebra mean that people may be mislead, so I may be mislead. A step in the game is one in which the skeptic's response is neutralized. I am not dreaming. Neutralizing responses should be allowed when it is as reasonable to accept the competitor and the neutralizer as to accept the competitor alone, the neutralizer may be used.
