"当观察者认为自己在观察一块石头时，他实际上是在观察石头对自己产生的影响，如果物理学是可信的话。"
— Bertrand Russell
Simplified Meaning:
When you look at a stone, you might think you are just seeing the stone itself. But actually, what you are really noticing is how the stone affects you. For example, you see the stone because light from the sun hits the stone and then bounces back to your eyes. What you see depends on how your eyes and brain process that light. Imagine tasting a delicious cake: the flavor you experience happens because your taste buds and brain react to the ingredients. In the same way, looking at the stone is about how your senses work with the stone’s impact on you. This idea teaches us that our perception is influenced by how our body reacts to things. Understanding this can help us realize that everyone might see the same object differently because of our unique experiences and senses.
