The chapter opens with a discussion of the concept of observation, or observation as an act of observation. It's important to note that the word "observation" doesn't just refer to the act of observing something; it also refers to the way in which we observe things. We're not just observing a thing, we're observing human beings as well, and this is just the tip of the iceberg. We learn that humans are crucial to the universe, and that human intentions are at the root of everything that happens in it. We also learn that the human body is like a collection of particles - it's like a skin, and we can observe it by looking at it. This is just one example of how humans can influence the world around them.
