“What has not been clear is that the potential of this emergency-born technology has always accrued to human's prewar individual initiatives taken in a humble but irrepressible progression of assumptions, measurements, deductions, and codifications of pure science.”

Amusing Ourselves to Death: Public Discourse in the Age of Show Business (1985)
Context: The Benedictine monks who invented the mechanical clock in the 12th and 13th centuries believed that such a clock would provide a precise regularity to the seven periods of devotion... here is a great paradox: the clock was invented by men who wanted to devote themselves more rigorously to God; and it ended as the technology of greatest use to men who wished to devote themselves to the accumulation of money. Technology always has unforeseen consequences, and it is not always clear, at the beginning, who or what will win, and who or what will lose.... Gutenberg thought his invention would advance the cause of the Holy Roman See, whereas in fact, it turned out to bring a revolution which destroyed the monopoly of the Church.

Literary and Historical Miscellanies (1855), The Necessity, the Reality, and the Promise of the Progress of the Human Race (1854)
Context: No science has been reached, no thought generated, no truth discovered, which has not from all time existed potentially in every human mind. The belief in the progress of the race does not, therefore, spring from the supposed possibility of his acquiring new faculties, or coming into the possession of a new nature.
Still less does truth vary. They speak falsely who say that truth is the daughter of time; it is the child of eternity, and as old as the Divine mind. The perception of it takes place in the order of time; truth itself knows nothing of the succession of ages. Neither does morality need to perfect itself; it is what it always has been, and always will be. Its distinctions are older than the sea or the dry land, than the earth or the sun. The relation of good to evil is from the beginning, and is unalterable.

Amusing Ourselves to Death: Public Discourse in the Age of Show Business (1985)
Context: Henry David Thoreau told us: "All our inventions are but improved means to an unimproved end." …Goethe told us: "One should, each day, try to hear a little song, read a good poem, see a fine picture, and, if it is possible, speak a few reasonable words." …Socrates told us: "The unexamined life is not worth living." …the prophet Micah told us: "What does the Lord require of thee but to do justly, and to love mercy and to walk humbly with thy God?" And I can tell you... what Confucius, Isaiah, Jesus, Mohammed, the Buddha, Spinoza and Shakespeare told us... There is no escaping from ourselves. The human dilemma is as it has always been, and we solve nothing fundamental by cloaking ourselves in technological glory.

It appears in multiple anti-vaccination books, all by Trung Nguyen and a co-writer, circa 2018. In September 2021 it is echoed everywhere, including medical-journal articles (on various subjects), with no source given. Right above the Aldous Huxley "quote", these books quote a much earlier anti-vax author. Coincidentally, that author says (elsewhere in his book) this:
Let us admire all-powerful Nature, which is not so easily brought into this serious and lasting disorder by our perverse intrusions; for otherwise, there would hardly have remained a human being alive.
