Ⅳ．Conclusion: Dare to Ask

In this essay, I argue that for facto problems, people should ask questions because humans can form justifiable knowledge through questioning. For normative questions, people should ask questions because humans can form intersubjective agreements that guide actions of a group of agents.

People should dare to ask. By doing so, we not only expand the scope of knowledge, but also challenge the established prejudices, and this is the road to the moral progress.
