Necessary Quotes (12 quotes)

Even mistaken hypotheses and theories are of use in leading to discoveries. This remark is true in all the sciences. The alchemists founded chemistry by pursuing chimerical problems and theories which are false. In physical science, which is more advanced than biology, we might still cite men of science who make great discoveries by relying on false theories. It seems, indeed, a necessary weakness of our mind to be able to reach truth only across a multitude of errors and obstacles.
— Claude Bernard
An Introduction to the Study of Experimental Medicine (1865, translation 1927, 1957), 170.

If you want to find out anything from the theoretical physicists about the methods they use, I advise you to stick closely to one principle: don't listen to their words, fix your attention on their deeds. To him who is a discoverer in this field the products of his imagination appear so necessary and natural that he regards them, and would like to have them regarded by others, not as creations of thought but as given realities.
— Albert Einstein
'On the Method of Theoretical Physics', quoted in Albert Einstein and Paul Arthur Schilpp (ed.), Albert Einstein: Philosopher-Scientist (1970), 338.

Indeed, we need not look back half a century to times which many now living remember well, and see the wonderful advances in the sciences and arts which have been made within that period. Some of these have rendered the elements themselves subservient to the purposes of man, have harnessed them to the yoke of his labors and effected the great blessings of moderating his own, of accomplishing what was beyond his feeble force, and extending the comforts of life to a much enlarged circle, to those who had before known its necessaries only.
— Thomas Jefferson
From paper 'Report of the Commissioners Appointed to Fix the Site of the University of Virginia' (Dec 1818), reprinted in Annual Report of the Board of Visitors of the University of Virginia for the Fiscal Year Ending May 31, 1879 (1879), 10.

Laws, in their most general signification, are the necessary relations arising from the nature of things. In this sense all beings have their laws: the Deity His laws, the material world its laws, the intelligences superior to man their laws, the beasts their laws, man his laws.
— Charles Louis de Secondat, Baron de Montesquieu
The Spirit of the Laws (1748), Vol. 1, book 1, 1.

Nature clasps all her creatures in a universal embrace; there is not one of them which she has not plainly furnished with all means necessary to the conservation of its being.
— Michel Eyquem de Montaigne

Science quotes on:  |  Approach (14)  |  Competition (15)  |  Humanist (4)  |  Scientist (186)  |  Support (19)

There is no philosophy which is not founded upon knowledge of the phenomena, but to get any profit from this knowledge it is absolutely necessary to be a mathematician.
— Daniel Bernoulli
Quoted in C. Truesdell, Essays in the History of Mathematics.
Science quotes on:  |  Knowledge (593)  |  Mathematician (95)  |  Phenomenon (100)  |  Philosophy (115)  |  Profit (12)

We cannot see how the evidence afforded by the unquestioned progressive development of organised existence—crowned as it has been by the recent creation of the earth's greatest wonder, MAN, can be set aside, or its seemingly necessary result withheld for a moment. When Mr. Lyell finds, as a witty friend lately reported that there had been found, a silver-spoon in grauwacke, or a locomotive engine in mica-schist, then, but not sooner, shall we enrol ourselves disciples of the Cyclical Theory of Geological formations.
— George Julius Poulett Scrope
Review of Murchison's Silurian System, Quarterly Review (1839), 64, 112-3.
Science quotes on:  |  Afford (2)  |  Creation (115)  |  Crown (10)  |  Cycle (11)  |  Development (97)  |  Disciple (2)  |  Earth (210)  |  Engine (8)  |  Evidence (74)  |  Existence (126)  |  Formation (29)  |  Friend (15)  |  Geology (135)  |  Greatest (17)  |  Locomotive (4)  |  Sir Charles Lyell (36)  |  Mankind (95)  |  Organization (45)  |  Progress (180)  |  Recent (7)  |  Report (10)  |  Result (103)  |  Silver (10)  |  Theory (319)  |  Wit (12)  |  Wonder (54)

When rich men are thus brought to regard themselves as trustees, and poor men learn to be industrious, economical, temperate, self-denying, and diligent in the acquisition of knowledge, then the deplorable strife between capital and labor, tending to destroy their fundamental, necessary, and irrefragable harmony will cease, and the world will no longer be afflicted with such unnatural industrial conflicts as we have seen during the past century...
— Peter Cooper
Address (31 May 1871) to the 12th annual commencement at the Cooper Union, honoring his 80th birthday, in New York City Mission and Tract Society, Annual report of the New York City Mission and Tract Society (1872), 69.

[D]iscovery should come as an adventure rather than as the result of a logical process of thought. Sharp, prolonged thinking is necessary that we may keep on the chosen road but it does not itself necessarily lead to discovery. The investigator must be ready and on the spot when the light comes from whatever direction.
— Theobald Smith
Letter to Dr. E. B. Krumhaar (11 Oct 1933), in Journal of Bacteriology (Jan 1934), 27, No. 1, 19.

[Young] was afterwards accustomed to say, that at no period of his life was he particularly fond of repeating experiments, or even of very frequently attempting to originate new ones; considering that, however necessary to the advancement of science, they demanded a great sacrifice of time, and that when the fact was once established, that time was better employed in considering the purposes to which it might be applied, or the principles which it might tend to elucidate.
— Hudson Gurney
Hudson Gurney, Memoir of the Life of Thomas Young, M.D. F.R.S. (1831), 12-3.
Science quotes on:  |  Advancement (21)  |  Application (56)  |  Attempt (31)  |  Consideration (36)  |  Demand (13)  |  Elucidation (4)  |  Establishment (15)  |  Experiment (346)  |  Fact (277)  |  Fond (2)  |  Frequently (6)  |  Life (379)  |  New (77)  |  Origination (5)  |  Particular (16)  |  Period (18)  |  Principle (87)  |  Purpose (57)  |  Repeat (8)  |  Sacrifice (12)  |  Tendency (16)  |  Time (129)  |  Thomas Young (12)



Carl Sagan Thumbnail At the heart of science is an essential balance between two seemingly contradictory attitudes--an openness to new ideas, no matter how bizarre or counterintuitive they may be, and the most ruthless skeptical scrutiny of all ideas, old and new. This is how deep truths are winnowed from deep nonsense. -- Carl Sagan
