"文化往往认为它只禁止不自然的东西。但从生物学的角度来看，没有什么是不自然的。任何可能的事情从定义上来说也是自然的。真正不自然的行为，即违背自然法则的行为，根本不可能存在。"
— Yuval Noah Harari
Simplified Meaning:
People often say that their cultural rules ban things that aren't "natural." However, if we look at it from a biological viewpoint, everything that happens in life is natural because it can occur. For example, some cultures might say that certain relationships are not natural, but from a biological standpoint, if those relationships happen, they are part of nature. Imagine how early humans might have thought it was unnatural to fly because birds do it and humans don't, but now airplanes make it clear that flying is just another possibility for humans. So, if something exists or can be done, it is natural. Anyone can apply this idea by being more open-minded and not judging others based on what they think is "unnatural." Instead, they can understand that nature is diverse and full of different possibilities, and people should accept that as part of life.
