"Retard" is a shortened form of "mentally retarded," and is a very unkind word for a person with a mental disability. Or written in a shorter form: bAnga
Aristotle spent his life asking questions and questioning everything and any definition, like what is truth, what does it mean to be, what is ugly, what defines living, etc think you can find it under "Socratic Questioning" on google ^_^
Doesn't make to much sense if it's about Aristotle, eh?
