When people get their mind made up about something, then it's: 'Don't bother me with facts.' They've got their minds made up and dismiss you out of hand. Some people don't even give you a fair hearing.
There is nothing more natural than to consider everything as starting from oneself, chosen as the center of the world; one finds oneself thus capable of condemning the world without even wanting to hear its deceitful chatter.
Man's worst ill is stubbornness of heart.
To say that men can be bullheaded would be insulting to the bull.
He who will not listen to any advice, nor be corrected in his writings, is a rank pedant.
Man seems to insist on ignoring the lessons available from history.
There is nothing to fear except the persistent refusal to find out the truth, the persistent refusal to analyze the causes of happenings.
I spoke to ears that refused to hear.
No man can be convinced when he will not.
Ignorance is stubborn and prejudice is hard.
No one cares to speak to an unwilling listener. An arrow never lodges in a stone: often it recoils upon the shooter of it.
Pride deafens us to the advice or warnings of those around us.
None so deaf as those that will not hear. None so blind as those that will not see.
