...A great philosophy is not a philosophy without reproach. It is a philosophy without fear.
A great philosophy is not a dictée. The greatest is not one that has no flaw.
A great philosophy is not one against which there is nothing to say. It is one that has said something.
And it is even one that had something to say. Even if it could not...[s]ay it.
It is not one that has no defects. It is not one that has no empty places. It is one that has full places.
