Sinclair Lewis

I believe it is an established maxim in morals that he who makes an assertion without knowing whether it is true or false, is guilty of falsehood; and the accidental truth of the assertion, does not justify or excuse him.
Abraham Lincoln
The tide of undecipherable signatures of mutinous adolescents which has washed over and bitten into the facades of monuments and the surface of public vehicles in the city where I live: graffiti as an assertion of disrespect, yes, but most of all simply an assertion... the powerless saying: I'm here, too.
Susan Sontag
The assertion fallacy ... is the fallacy of confusing the conditions for the performance of the speech act of assertion with the analysis of the meaning of particular words occurring in certain assertions.
John Searle
Some old poet's grand imagination is imposed on us as adamantine everlasting truth, and God's own word! Pythagoras says, truly enough, "A true assertion respecting God, is an assertion of God"; but we may well doubt if there is any example of this in literature.
Henry David Thoreau
There is one thing to be remembered: that the assertion—I am God—cannot be made with regard to the sense-world.
