"我在生活中学到两个教训：第一，没有充足的文学、心理或历史方面的答案可以解释人类的悲剧。第二，没有悲剧的答案，只有沉默的答案。"

Simplified Meaning:

The quote is saying that when tragedy happens in life, books, studies, or history do not give us the answers we need. Imagine someone losing a loved one. Reading about grief or the science behind our emotions won't take away their pain or give them clear answers to their sadness. The second part of the quote means that in the face of such deep sadness, there are no big, dramatic answers that make everything better. Often, the best thing we can do is simply to be quiet and be there for each other. For example, if a friend is going through something tough, sometimes just sitting with them in silence helps more than trying to say the perfect thing. So, the advice here is that in hard times, we often find more comfort in quiet presence and support, rather than looking for explanations or grand solutions.
