Guarantee Quotes (16 quotes)

...Furthermore, an inducement must be offered to those who are engaged in the industrial exploitation of natural sources of power, as waterfalls, by guaranteeing greater returns on the capital invested than they can secure by local development of the prop

A new species develops if a population which has become geographically isolated from its parental species acquires during this period of isolation characters which promote or guarantee reproductive isolation when the external barriers break down.
Systematics and the Origin of Species: From the Viewpoint of a Zoologist (1942), 155.

An indispensable hypothesis, even though still far from being a guarantee of success, is however the pursuit of a specific aim, whose lighted beacon, even by initial failures, is not betrayed.
Nobel Lecture (2 Jun 1920), in Nobel Lectures in Physics, 1901-1921 (1998), 407.

Encryption...is a powerful defensive weapon for free people. It offers a technical guarantee of privacy, regardless of who is running the government... It’s hard to think of a more powerful, less dangerous tool for liberty.

I like the word “nanotechnology.” I like it because the prefix “nano” guarantees it will be fundamental science for decades; the “technology” says it is engineering, something you’re involved in not just because you’re interested in how nature works but because it will produce something that has a broad impact.
From interview in 'Wires of Wonder', Technology Review (Mar 2001), 104, No. 2, 88.

I'm not saying … I'm gonna change the world, but I guarantee you that I will spark the brain that will change the world.

In the last analysis the best guarantee that a thing should happen is that it appears to us as vitally necessary.
In Teilhard de Chardin and Sara Appleton-Weber (trans.), The Human Phenomenon (1999, 2003), 163. Originally published in French as Le Phιnomene Humain (1955).

Nothing that you do in science is guaranteed to result in benefits for mankind. Any discovery, I believe, is morally neutral and it can be turned either to constructive ends or destructive ends. That’s not the fault of science.
Quoted by Jeremy Pearce in 'Arthur Galston, Agent Orange Researcher, Is Dead at 88', New York Times (23 Jun 2008), B6.

Now any dogma, based primarily on faith and emotionalism, is a dangerous weapon to use on others, since it is almost impossible to guarantee that the weapon will never be turned on the user.
In The Foundation Trilogy (1951), 155.
Science quotes on:  |  Danger (62)  |  Dogma (25)  |  Emotion (62)  |  Faith (131)  |  Impossible (68)  |  Turn (72)  |  User (4)  |  Weapon (57)

Our advanced and fashionable thinkers are, naturally, out on a wide swing of the pendulum, away from the previous swing of the pendulum.... They seem to have an un-argue-out-able position, as is the manner of sophists, but this is no guarantee that they are right.
In Science is a Sacred Cow (1950), 177-78.
Science quotes on:  |  Advance (123)  |  Fashion (24)  |  Pendulum (13)  |  Swing (8)  |  Thinking (222)

Simplification of modes of proof is not merely an indication of advance in our knowledge of a subject, but is also the surest guarantee of readiness for farther progress.
In Lord Kelvin and Peter Guthrie Tait Elements of Natural Philosophy (1873), Preface.
Science quotes on:  |  Advance (123)  |  Father (44)  |  Indication (21)  |  Knowledge (1128)  |  Merely (35)  |  Mode (29)  |  Progress (317)  |  Proof (192)  |  Readiness (5)  |  Simplification (12)  |  Subject (129)  |  Surest (5)

There is no way to guarantee in advance what pure mathematics will later find application. We can only let the process of curiosity and abstraction take place, let mathematicians obsessively take results to their logical extremes, leaving relevance far behind, and wait to see which topics turn out to be extremely useful. If not, when the challenges of the future arrive, we won’t have the right piece of seemingly pointless mathematics to hand.
In 'The Unplanned Impact of Mathematics', Nature (14 Jul 2011), 475, No. 7355, 167.
Science quotes on:  |  Abstraction (29)  |  Advance (123)  |  Application (117)  |  Challenge (37)  |  Curiosity (89)  |  Future (229)  |  Pointless (3)  |  Process (201)  |  Pure Mathematics (27)  |  Relevance (12)

To connect the dinosaurs, creatures of interest to everyone but the veriest dullard, with a spectacular extra­terrestrial event like the deluge of meteors … seems a little like one of those plots that a clever publisher might concoct to guarantee enormous sales. All the Alvarez-Raup theories lack is some sex and the involvement of the Royal family and the whole world would be paying attention to them.
In The Canberra Times (20 May 1984).

Alvarez (23)  |  Attention (76)  |  Clever (14)  |  Concoct (2)  |  Connect (15)  |  Creature (127)  |  Deluge (7)  |  Dinosaur (23)  |  Dullard (2)  |  Enormous (33)  |  Event (97)  |  Extraterrestrial (3)  |  Family (37)  |  Interest (170)  |  Involvement (4)  |  Lack (52)  |  Little (126)  |  Meteor (14)  |  Plot (9)  |  Publisher (2)  |  David Malcolm Raup (2)  |  Royal (10)  |  Sale (3)  |  Sex (48)  |  Spectacular (8)  |  Theory (582)  |  World (667)

Whether true or false, others must judge; for the firmest conviction of the truth of a doctrine by its author, seems, alas, not to be the slightest guarantee of truth.
Letter (1 May 1857) to Alfred Russel Wallace. In ‎Sir Francis Darwin (ed.), The Life and Letters of Charles Darwin (1887), 454.
Science quotes on:  |  Author (39)  |  Conviction (57)  |  Doctrine (53)  |  False (79)  |  Judge (43)  |  Truth (750)

[Kepler] had to realize clearly that logical-mathematical theoretizing, no matter how lucid, could not guarantee truth by itself; that the most beautiful logical theory means nothing in natural science without comparison with the exactest experience. Without this philosophic attitude, his work would not have been possible.
From Introduction that Einstein wrote for Carola Baumgardt and Jamie Callan, Johannes Kepler Life and Letters (1953), 13.
Science quotes on:  |  Attitude (47)  |  Beautiful (81)  |  Clearly (17)  |  Comparison (53)  |  Experience (268)  |  Johannes Kepler (72)  |  Logic (187)  |  Mathematics (587)  |  Matter (270)  |  Natural Science (62)  |  Philosophy (213)  |  Possible (100)  |  Realize (43)  |  Theory (582)  |  Truth (750)  |  Work (457)

[This] may prove to be the beginning of some embracing generalization, which will throw light, not only on radioactive processes, but on elements in general and the Periodic Law.... Chemical homogeneity is no longer a guarantee that any supposed element is not a mixture of several of different atomic weights, or that any atomic weight is not merely a mean number.
From Chemical Society's Annual Reports (1910), Vol. 7, 285. As quoted in Francis Aston in Lecture (1936) on 'Forty Years of Atomic Theory', collected in Needham and Pagel (eds.) in Background to Modern Science: Ten Lectures at Cambridge Arranged by the History of Science Committee, (1938), 100. Cited in Alfred Walter Stewart, Recent Advances in Physical and Inorganic Chemistry (1920), 198.

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
