“A precept claiming infallibility should certainly possess the universality of the law of gravitation and the perfection of the arithmetical table. If it fails to possess these undeviating qualities, its imperfection is self-evident and its value either greatly diminished or useless.”

Madame Bovary

Space, Time and Gravitation (1920)
Context: We can see that, the constant in the law of gravitation being fixed, there may be some upper limit to the amount of matter possible; as more and more matter is added in the distant parts, space curves round and ultimately closes; the process of adding more matter must stop, because there is no more space, and we can only return to the region already dealt with. But there seems nothing to prevent a defect of matter, leaving space unclosed. Some mechanism seems to be needed, whereby either gravitation creates matter, or all the matter in the universe conspires to define a law of gravitation.<!--p.163

Source: The Philosopher's Stone (1969), p. 317-318
Context: Man should possess an infinite appetite for life. It should be self-evident to him, all the time, that life is superb, glorious, endlessly rich, infinitely desirable. At present, because he is in a midway position between the brute and the truly human, he is always getting bored, depressed, weary of life. He has become so top-heavy with civilisation that he cannot contact the springs of pure vitality. Control of the prefrontal cortex will change all of this. He will cease to cast nostalgic glances towards the womb, for he will realise that death is no escape. Man is a creature of life and the daylight; his destiny lies in total objectivity.
