We are all born ignorant; but one must work hard to remain stupid.
Real knowledge is to know the extent of one's ignorance.
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.
Nothing amazes me anymore.
