Passage 1
“We are misled by considering any complicated machine as a single thing; in truth it is a city or society, each member of which was bred truly after its kind. We see a machine as a whole, we call it by a name and individualise it; we look at our own limbs, and know that the combination forms an individual which springs from a single centre of reproductive action; we therefore assume that there can be no reproductive action which does not arise from a single centre; but this assumption is unscientific, and the bare fact that no vapour-engine was ever made entirely by another, or two others, of its own kind, is not sufficient to warrant us in saying that vapour-engines have no reproductive system. The truth is that each part of every vapour-engine is bred by its own special breeders, whose function it is to breed that part, and that only, while the combination of the parts into a whole forms another department of the mechanical reproductive system, which is at present exceedingly complex and difficult to see in its entirety.”
The passage argues that machines should be understood as organized reproductive systems rather than as isolated human instruments. By analogy with biological reproduction and evolution, it opens the possibility that machines may develop and succeed humanity. The surrounding argument treats this prospect as a future danger requiring human vigilance, though the excerpt itself mainly establishes the analogy rather than describing an explicit conflict of machine and human purposes.
