"To attempt seeing Truth without knowing Falsehood. It is the attempt to see the Light without knowing the Darkness. It cannot be"

This quote by Frank Herbert speaks with the concept that it is impossible to understand reality without very first understanding falsehood. It is impossible to appreciate the light without first understanding the darkness. This is since the 2 principles are inextricably connected. To understand one, we should understand the other. Without comprehending the darkness, we can not appreciate the light. Without comprehending fallacy, we can not appreciate reality. This quote is a pointer that we should know both sides of the coin in order to really comprehend the world around us. We need to want to accept both the excellent and the bad in order to get a full understanding of the world. Without this understanding, we can not genuinely value the fact.
