„The metals are all essentially identical; they differ only in form. Now, the form brings out accidental causes, which the experimenter must try to discover and remove, as far as possible. Accidental causes impede the regular union of sulphur and mercury; for every metal is a combination of sulphur and mercury. A diseased womb may give birth to a weakly, leprous child, although the seed was good; the same is true of the metals which are generated in the bowels of the earth, which is a womb for them; any cause whatever, or local trouble, may produce an imperfect metal. When pure sulphur comes in contact with pure mercury, after more or less time, and by the permanent action of nature, gold is produced.“

As quoted by Francis Preston Venable, A Short History of Chemistry (1894) p. 28. https://books.google.com/books?id=fN9YAAAAYAAJ&pg=PA28

„A lesser-known fact about the geopolitics of resources has escaped public polemics. This refers to rare earth metals or rare-earth elements (REMs), a set of 17 naturally occurring non-toxic materials, which play a pivotal role for emerging technologies and which are predominantly produced and exported from China.“

„I have my ideal, and it is very pure, and very sacred to me. But yours, equally sacred, may be different and we may both be wrong. But certain am I that with free contract, that form of sexual association will survive which is best adapted to time and place, thus producing the highest evolution of the type.“

Sex Slavery (1890)
Contexto: Now for the remedy. It is in one word, the only word that ever brought equity anywhere — LIBERTY! Centuries upon centuries of liberty is the only thing that will cause the disintegration and decay of these pestiferous ideas. Liberty was all that calmed the bloodwaves of religious persecution! You cannot cure serfhood by any other substitution. Not for you to say "in this way shall the race love." Let the race alone.
Will there not be atrocious crimes? Certainly. He is a fool who says there will not be. But you can't stop them by committing the arch-crime and setting a block between the spokes of Progress-wheels. You will never get right until you start right.
As for the final outcome, it matters not one iota. I have my ideal, and it is very pure, and very sacred to me. But yours, equally sacred, may be different and we may both be wrong. But certain am I that with free contract, that form of sexual association will survive which is best adapted to time and place, thus producing the highest evolution of the type. Whether that shall be monogamy, variety, or promiscuity matters naught to us; it is the business of the future, to which we dare not dictate.

„Contrary to the vulgar illusion, it is thanks to the metal, and by virtue of it, that the pilot rediscovers nature. As I have already said, the machine does not isolate man from the great problems of nature but plunges him more deeply into them.“

Ch III : The Tool
Terre des Hommes (1939)
Contexto: !-- There was a time when a flyer sat at the centre of a complicated works. Flight set us factory problems. The indicators that oscillated on the instrument panel warned us of a thousand dangers. But in the machine of today we forget that motors are whirring: the motor, finally, has come to fulfil its function, which is to whirr as a heart beats—and we give no thought to the beating of our heart. Thus, --> Precisely because it is perfect the machine dissembles its own existence instead of forcing itself upon our notice.
And thus, also, the realities of nature resume their pride of place. It is not with metal that the pilot is in contact. Contrary to the vulgar illusion, it is thanks to the metal, and by virtue of it, that the pilot rediscovers nature. As I have already said, the machine does not isolate man from the great problems of nature but plunges him more deeply into them.
Numerous, nevertheless, are the moralists who have attacked the machine as the source of all the ills we bear, who, creating a fictitious dichotomy, have denounced the mechanical civilization as the enemy of the spiritual civilization.
If what they think were really so, then indeed we should have to despair of man, for it would be futile to struggle against this new advancing chaos. The machine is certainly as irresistible in its advance as those virgin forests that encroach upon equatorial domains.
