We should be ready at all time to ask questions about what we don’t know irrespective of what people will feel or say about it.

Many at times, this has restricted people from asking questions. Especially in school, the university classes, one wise crack from a mischievious colleague can dampen one's enthusiasm to learn. I think the people as a whole should welcome the act of questioning and be ready to help with answers if they can.

The greatest scientists and philosophers did ask questions. We would be ages backward if they didn't.
