Nothing strengthens authority so much as silence.

Anyone who conducts an argument by appealing to authority is not using his intelligence he is just using his memory

Anyone who in discussion relies upon authority uses, not his understanding, but rather his memory.

Anyone who conducts an argument by appealing to authority is not using his intelligence; he is just using his memory.

People talk to people who perceive nothing, who have open eyes and see nothing; they shall talk to them and receive no answer; they shall adore those who have ears and hear nothing; they shall burn lamps for those who do not see.

As a well-spent day brings happy sleep, so a life well used brings happy death.
