Constructed Quotes (3 quotes)

La Chimie n’est pas une science primitive, comme la géométrie ou l’astronomie; elle s’est constituée sur les débris d’une formation scientifique antérieure; formation demi-chimérique et demi-positive, fondée elle-même sur le trésor lentement amassé des découvertes pratiques de la métallurgie, de la médecine, de l’industrie et de l’économie domestique. Il s’agit de l’alchimie, qui prétendait à la fois enrichir ses adeptes en leur apprenant à fabriquer l’or et l’argent, les mettre à l’abri des maladies par la préparation de la panacée, enfin leur procurer le bonheur parfait en les identifiant avec l’âme du monde et l’esprit universel.
Chemistry is not a primitive science like geometry and astronomy; it is constructed from the debris of a previous scientific formation; a formation half chimerical and half positive, itself found on the treasure slowly amassed by the practical discoveries of metallurgy, medicine, industry and domestic economy. It has to do with alchemy, which pretended to enrich its adepts by teaching them to manufacture gold and silver, to shield them from diseases by the preparation of the panacea, and, finally, to obtain for them perfect felicity by identifying them with the soul of the world and the universal spirit.
From Les Origines de l’Alchemie (1885), 1-2. As quoted by Harry Shipley Fry in 'An Outline of the History of Chemistry Symbolically Represented in a Rookwood Fountain', The Journal of Industrial and Engineering Chemistry (1 Sep 1922), 14, No. 9, 868.

In all works on Natural History, we constantly find details of the marvellous adaptation of animals to their food, their habits, and the localities in which they are found. But naturalists are now beginning to look beyond this, and to see that there must be some other principle regulating the infinitely varied forms of animal life. It must strike every one, that the numbers of birds and insects of different groups having scarcely any resemblance to each other, which yet feed on the same food and inhabit the same localities, cannot have been so differently constructed and adorned for that purpose alone. Thus the goat-suckers, the swallows, the tyrant fly-catchers, and the jacamars, all use the same kind ‘Of food, and procure it in the same manner: they all capture insects on the wing, yet how entirely different is the structure and the whole appearance of these birds!
In A Narrative of Travels on the Amazon and Rio Negro (1853), 83-84.

It is not within the power of the properly constructed human mind to he satisfied. Progress would cease if this were the case.
From Cameron Prize Lecture (1928), delivered before the University of Edinburgh. As quoted in J.B. Collip 'Frederick Grant Banting, Discoverer of Insulin', The Scientific Monthly (May 1941), 52, No. 5, 474.

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
