"The butchering of harmless animals cannot fail to produce much of that spirit of insane and hideous exultation in which news of a victory is related altho' purchased by the massacre of a hundred thousand men. If the use of animal food be in consequence, subversive to the peace of human society, how unwarrantable is the injustice and barbarity which is exercised toward these miserable victims. They are called into existence by human artifice that they may drag out a short and miserable existence of slavery and disease, that their bodies may be mutilated, their social feelings outraged. It were much better that a sentient being should never have existed, than that it should have existed only to endure unmitigated misery."

“Poets are the hierophants of an unapprehended inspiration; the mirrors of the gigantic shadows which futurity casts upon the present; the words which express what they understand not; the trumpets which sing to battle, and feel not what they inspire; the influence which is moved not, but moves. Poets are the unacknowledged legislators of the world.”

“It is probable that what we call thought is not an actual being, but no more than the relation between certain parts of that infinitely varied mass, of which the rest of the universe is composed, and which ceases to exist as soon as those parts change their position with regard to each other.”

“If a person's religious ideas correspond not with your own, love him nevertheless. How different would yours have been, had the chance of birth placed you in Tartary or India!”
