"You shall not wear cloth of wool and linen mixed together."
- Deuteronomy 22:11
Your sense of sight is color and form. Your sense of hearing is sound. Though they both inform you about the nature of your world of experience, we can't thereby say, "I am hearing the color blue." It's a confused idea. The world of hearing has nothing to do with the world of sight. They are separate worlds of experience.
While this much is obvious, Michael Oakeshott clarifies other, less obvious, kinds of confusion. By the way he sees things, the worlds of Science, History, and Practice are towards each other like sight and hearing are towards each other.
