Whenever any one informs us that he has found a man who knows all the arts, and all things else that anybody knows, and every single thing with a higher degree of accuracy than any other man - whoever tells us this, I think that we can only imagine him to be a simple creature who is likely to have been deceived by some wizard or actor whom he met, and whom he thought all-knowing, because he himself was unable to analyse the nature of knowledge and ignorance and imitation.
SocratesNothing very new. By taking good care of yourselves you are of service to me and my family as well as yourselves, no matter what you do, even if you don't think so at present. But if you neglect yourselves and are unwilling to live, as though following tracks, in accordance with what we now say and have said in the past too, then no matter how much or how seriously you agree with me at present you will accomplish next to nothing.
Socrates
