WISDOM IS KNOWING YOU ARE NOT WISE

The great Greek philosopher Plato described Socrates his teacher as the wisest man. This was despite Socrates claiming to lack knowledge or wisdom. The debate on wisdom started when Socrates and his friend decided to visit an Oracle to find out if there was someone more wise than Socrates. The Oracle confirmed that indeed it is Socrates who was the  wisest. Puzzled as to how the Oracle reached that conclusion, Socrates decided to study poets, politicians, and other craftsmen. He discovered that many people who claim to have immense knowledge on a given matter either know little or nothing at all.
It is difficult to know exactly how the Oracle interpreted wisdom. But the simplest idea would be that the wisest person is that who does not claim to have knowledge. The knowledge of matters of this world are so big that no matter how much we know about something, there is even much more that we cannot know. Even for someone who is considered an expert, the knowledge they have is just a drop in the ocean of all knowledge regarding their subject of specialty. Therefore claiming to be wise is claiming to know everything or claiming to know more than you actually do. When you are wise then you do not need or seek more knowledge.
The wisest person is hence that who knows that they do not know a lot. The wisest person is that who is constantly seeking more knowledge to nourish themselves and grow better. Wisdom is constantly seeking knowledge. Therefore to be wise is to know that you are not wise.
