"信仰是不需要证据和理由的相信，巧合的是，这也是妄想的定义。"

Simplified Meaning:

Believing in something without seeing proof or logical reasons can be called faith. But if someone continues to believe in it despite all evidence showing it's untrue, that can cross into delusion. For example, imagine a person who firmly believes they can fly just by flapping their arms. Without any evidence to support this belief and with science clearly showing humans can't fly this way, their strong belief might be seen as delusional. In everyday life, faith can be positive, like having hope or trusting a friend. However, it's important to balance faith with reason. Suppose someone believes that exercising will make them healthier. That belief is supported by evidence and reason, unlike believing they can fly by flapping their arms. So, while it's good to have faith, we should also seek out evidence and use common sense to guide our beliefs and actions.
