...we all know that in all matters of mere opinion that [every] man is insane-just as insane as we are...we know exactly where to put our finger upon his insanity: it is where his opinion differs from ours....All Democrats are insane, but not one of them knows it. None but the Republicans. All the Republicans are insane, but only the Democrats can perceive it. The rule is perfect: in all matters of opinion our adversaries are insane.
[I] shall never use profanity except in discussing house rent and taxes. Indeed, upon second thought, I will not use it then, for it is unchristian, inelegant, and degrading--though to speak truly I do not see how house rent and taxes are going to be discussed worth a cent without it.

They take part of a verb and put it down here, like a stake, and they take the other part of it and put it away over yonder like another stake, and between these two limits they just shovel in German. from "Disappearance of Literature
Such is professional jealousy; a scientist will never show any kindness for a theory which he did not start himself. There is no feeling of brotherhood among these people. Indeed, they always resent it when I call them brother.
