"We do not fear censorship for we have no wish to offend with improprieties or obscenities, but we do demand, as a right, the liberty to show the dark side of wrong, that we may illuminate the bright side of virtue -- the same liberty that is conceded to the art of the written word, that art to which we owe the Bible and the works of Shakespeare."
"I am of course confident that I will fulfill my tasks as a writer in all circumstances -- from my grave even more successfully and more irrefutably than in my lifetime. No one can bar the road to truth, and to advance its cause I am prepared to accept even death. But may it be that repeated lessons will finally teach us not to stop the writer's pen during his lifetime? At no time has this ennobled our history."
