„The more necessary a thing is for living beings, the more easily it is found and the cheaper it is; the less necessary it is, the rarer and dearer it is.“

Kontext: In a free system any large, popular, revolutionary movement should be able to bring about its ends by such a voluntary process. As more and more people see how it works more and more will wish to participate in or support it. And so it will grow, without being necessary to force everyone or a majority or anyone into the pattern.

This has been attributed to Pessoa. Indeed, it is from Plutarch's "Parallel Lives", about Pompeus, when demanding that soldiers board the ships, when they were afraid of dying at sea.

Evolution of living organisms: evidence for a new theory of transformation (1977)
Original: Le philosophe, considérant l'univers dans son intégralité, est conduit à n'admettre qu'un seul être nécessaire, absolu, Dieu. Tous les autres sont contingents; c'est pour cela que Pascal disait de lui-même : « Je sens que je puis n'avoir pas été... donc je ne suis pas un être nécessaire » (Pensées, 597). Cette proposition s'applique avec autant de justesse à tout être

Penguin Island (1908)
Kontext: Penguinia gloried in its wealth. Those who produced the things necessary for life, wanted them; those who did not produce them had more than enough. "But these," as a member of the Institute said, "are necessary economic fatalities." The great Penguin people had no longer either traditions, intellectual culture, or arts. The progress of civilisation manifested itself among them by murderous industry, infamous speculation, and hideous luxury. Its capital assumed, as did all the great cities of the time, a cosmopolitan and financial character. An immense and regular ugliness reigned within it. The country enjoyed perfect tranquillity. It had reached its zenith.

我们就生活在这样一个复杂的世界中，我们认为中国人没必要因为给那些西方精英讲不通而懊恼。重要的是，他们拿新疆问题发难起不了什么实际作用，这些攻击是很热闹，但又很虚无的一堆泡沫。
