just a thought

 No matter how vast your knowledge or how modest, it is your own mind that has to acquire it.  It is only with your own knowledge that you can deal.  It is only your own knowledge that you can claim to possess or ask others to consider.  Your mind is your only judge of truth — and if others dissent from your verdict, reality is the court of final appeal.  Nothing but a man’s mind can perform that complex, delicate, crucial process of identification which is thinking.  Nothing can direct the process but his own judgment.  Nothing can direct his judgment but his moral integrity….A rational process is a moral process.  You may make an error at any step of it, with nothing to protect you but your own severity, or you may try to cheat, to fake the evidence and evade the effort of the quest — but if devotion to truth is the hallmark of morality, then there is no greater, nobler, more heroic form of devotion than the act of a man who assumes responsibility for thinking.
