"宇宙中存在的所有事物都是偶然和必然的结果。"

Simplified Meaning:

Everything we see in the world around us, from the stars in the sky to the smallest insects, exists because of two main reasons: chance and necessity. Chance refers to random events that happen without any specific plan, like a genetic mutation in an animal that helps it survive. Necessity means these things happen because they need to; they fulfill some essential role. For instance, trees exist because they are needed to produce oxygen and provide habitats. Think of it like baking a cake: sometimes you add an extra ingredient by accident (chance), but you always need flour and eggs (necessity) to make it work. In life, this idea teaches us that while some things happen randomly, others must happen to keep everything running smoothly. Understanding this can help us see the balance between randomness and order in the universe.
