We are all born ignorant; but one must work hard to remain stupid.
Human behavior flows from three main sources: desire; emotion; and knowledge.
To know what you know and what you do not know; that is true knowledge.
Knowledge has to be improved; challenged; and increased constantly; or it vanishes.
To know that we know what we know; and to know that we do not know what we do not know; that is true knowledge.
A wholesome oblivion of one's neighbours is the beginning of wisdom.
