Socrates said, ‘A wise man knows that he knows nothing.’ It isn’t possible to comprehend exactly how much you don’t know if you don’t know a tiny bit to begin with. Understanding the sheer magnitude of knowledge and understanding out there is one of the first things encountered by someone who seeks to understand the world.
Understanding the self is no different. For the unexamined life, ‘knowing’ oneself is most likely a mix of emotions and ‘gut feelings.’ Nietzsche’s quote gets at the reason behind that – understanding oneself, like understanding any singular topic, is not a trivial task.
