Passage Summary: Since it's easier to make a computer think like a human than it is to make it see like a human, we must understand thinking better than seeing.

Conclusion: It seems we have a deeper understanding of our analytical mental functions than we do of our sensory perceptions.

Reasoning: It is much easier to program a computer to perform logical tasks like chess than it is to program it to process visual information.

Analysis: The argument makes a leap from 'ease of computer modeling' to 'depth of human understanding.' To justify this, we need a principle that links the two: if we can model something easily on a computer, it implies we understand that process well. Look for an answer that establishes this connection between the success of artificial simulation and the level of human knowledge.
