“The fact that man knows right from wrong proves his intellectual superiority to the other creatures; but the fact that he can do wrong proves his moral inferiority to any creatures that cannot.”
“All the arguments to prove man's superiority cannot shatter this hard fact: in suffering the animals are our equals.”
“Every man has a right to his own opinion, but no man has a right to be wrong in his facts”
“... a man doesn't like to have his ego popped, especially when he prides himself on his sagacity, and then to be proved wrong by a man who claims he doesn't know anything.”
“Occasionally we all do wrong things from right motives. Only time can prove us right or wrong. The past is the past. Nothing can change it now, and who is to say that it was all wrong, anyway?”
“We are all capable of believing things which we know to be untrue, and then, when we are finally proved wrong, impudently twisting the facts so as to show that we were right.”
