Ferment Quotes (4 quotes)

By teaching us how to cultivate each ferment in its purity—in other words, by teaching us how to rear the individual organism apart from all others,—Pasteur has enabled us to avoid all these errors. And where this isolation of a particular organism has been duly effected it grows and multiplies indefinitely, but no change of it into another organism is ever observed. In Pasteur’s researches the Bacterium remained a Bacterium, the Vibrio a Vibrio, the Penicillium a Penicillium, and the Torula a Torula. Sow any of these in a state of purity in an appropriate liquid; you get it, and it alone, in the subsequent crop. In like manner, sow smallpox in the human body, your crop is smallpox. Sow there scarlatina, and your crop is scarlatina. Sow typhoid virus, your crop is typhoid—cholera, your crop is cholera. The disease bears as constant a relation to its contagium as the microscopic organisms just enumerated do to their germs, or indeed as a thistle does to its seed.
In 'Fermentation, and its Bearings on Surgery and Medicine', Essays on the Floating­Matter of the Air in Relation to Putrefaction and Infection (1881), 264.

By the act of generation nothing more is done than to ferment the sperm of ye female by the sperm of ye male that it may thereby become fit nourishment for ye Embryo: ffor ye nourishment of all animals is prepared by ferment & the ferment is taken from animals of the same kind, & makes the nourishment subtile & spiritual. In adult animals the nourishmt is fermented by the choler and pancreatic juice both wch come from the blood. The Embryo not being able to ferment its own nourishment wch comes from the mothers blood has it fermented by the sperm wch comes from ye fathers blood, & by this nourishment it swells, drops off from ye Ovarium & begins to grow with a life distinct from that of ye mother.
From 'Quζst 25' in Draft version of The Queries manuscript, Add. MS. 3970, folio 235 held by the University of Cambridge Library. As quoted and cited in R.W. Home, 'Force, Electricity, and Living Matter', from Margaret J. Osler and ‎Paul Lawrence Farber (eds.), Religion, Science, and Worldview: Essays in Honor of Richard S. Westfall (2002), 113.

I propose to provide proof... that just as always an alcoholic ferment, the yeast of beer, is found where sugar is converted into alcohol and carbonic acid, so always a special ferment, a lactic yeast, is found where sugar is transformed into lactic acid. And, furthermore, when any plastic nitrogenated substance is able to transform sugar into that acid, the reason is that it is a suitable nutrient for the growth of the [lactic] ferment.
Comptes Rendus (1857), 45, 913.

Thus you may multiply each stone 4 times & no more for they will then become oyles shining in ye dark and fit for magicall uses. You may ferment them with ☉ [gold] and [silver], by keeping the stone and metal in fusion together for a day, & then project upon metalls. This is the multiplication of ye stone in vertue. To multiply it in weight ad to it of ye first Gold whether philosophic or vulgar.
Praxis (c.1693), quoted in Betty Jo Teeter Dobbs, The Janus Faces of Genius: The Role of Alchemy In Newton's Thought (1991), 304.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
