Quote by Lord (John Emerich Edward Dalber
There are two things which cannot be attacked in front: ignorance and narrow-mindedness. They can only be shaken by the simple development of the contrary qualities. They will not bear discussion.

Summary
This quote emphasizes that ignorance and narrow-mindedness cannot be attacked head-on. Instead, the best approach is to challenge them by cultivating opposing qualities such as knowledge and open-mindedness. Arguing or debating with these traits is fruitless as they are often resistant to logical reasoning or discussion. Thus, the best way to overcome ignorance and narrow-mindedness is to promote personal growth and the development of alternative perspectives.
