“In manufacturing food for its own cells, the plant is producing a supply of food that will be available for the sustenance of animal cells also. Thus the entire animal World may be said to be a vast parasitic colony as absolutely dependent upon the vegetable colony for its essential food supplies as any other parasite is dependent upon its host.”

“People sometimes forget that there are vegetables and vegetables. There are vegetables that have not so much nutriment in them; but there are others – all the farinaceous foods such as wheat and barley – which contain a greater amount of nutriment than beef or any other animal meat.”

“No one at all understands why it is possible for the plant cell that bears within its substance one of these green chlorophyll bodies to combine certain inorganic elements into nutritious foods, a feat that no human chemist can perform.”

“The vulgar opinion, then, which, on health reasons, condemns vegetable food and so much praises animal food, being so ill-founded, I have always thought it well to oppose myself to it, moved both by experience and by that refined knowledge of natural things which some study and conversation with great men have given me. And perceiving now that such my constancy has been honoured by some learned and wise physicians with their authoritative adhesion, I have thought it my duty publicly to diffuse the reasons of the Pythagorean diet, regarded as useful in medicine, and, at the same time, as full of innocence, of temperance, and of health. And it is none the less accompanied with a certain delicate pleasure, and also with a refined and splendid luxury, if care and skill be applied in selection and proper supply of the best vegetable food, to which the fertility and the natural character of our beautiful country seem to invite us.”

Antonio Cocchi (1695–1758) Italian physician and naturalist

“With the right of the scientist to investigate most aspects of the material universe, most persons will agree; but there are some who have questioned the applicability of scientific methods to an investigation of human sexual behavior…. It is as though the dietician and biochemist were denied the right to analyze foods and the processes of nutrition, because the cooking and proper serving of food may be rated a fine art, and because the eating of certain foods has been considered a matter for religious regulation.”

Alfred Kinsey (1894–1956) American scientist (1894–1956)

“Don't ask God to bless junk food and miraculously transform it so that it has nutritional value. That's not how God works.”

“It's no coincidence that an acute sensibility to the condition of animals comes up at the same time as industrialised food and concentration camp style farming.”

Gilles Dauvé (1947) French writer

"Letter on Animal Liberation" (1999)

“And see, a kind, refined lady will devour the carcasses of these animals with full assurance that she is doing right, at the same time asserting two contradictory propositions: First, that she is, as her doctor assures her, so delicate that she cannot be sustained by vegetable food alone, and that for her feeble organism flesh is indispensable; and, secondly, that she is so sensitive that she is unable, not only herself to inflict suffering on animals, but even to bear the sight of suffering. Whereas the poor lady is weak precisely because she has been taught to live upon food unnatural to man; and she cannot avoid causing suffering to animals — for she eats them.”

Leo Tolstoy (1828–1910) Russian writer
