- Premise 1
- If one's visual world is merely a mental image of the external world, then visual perception must involve the creation, and then internal perception, of that mental image.
- see also:
- Chain 10: The mental image of the external world created during visual perception is not in turn perceived in order to be experienced.
- Premise 2
- If visual perception involves the creation, and then internal perception, of a mental image of the external world, then that internal perception must in turn involve the creation of an image of the first image, which must in turn be perceived, involving the creation of an image of the second image, and so on.
- Conclusion
- If one's visual world is merely a mental image of the external world, then the visual process must involve the creation of an infinite series of mental images, with that process therefore never reaching completion.
