Unforeseen Quotes (11 quotes)

… just as the astronomer, the physicist, the geologist, or other student of objective science looks about in the world of sense, so, not metaphorically speaking but literally, the mind of the mathematician goes forth in the universe of logic in quest of the things that are there; exploring the heights and depths for facts—ideas, classes, relationships, implications, and the rest; observing the minute and elusive with the powerful microscope of his Infinitesimal Analysis; observing the elusive and vast with the limitless telescope of his Calculus of the Infinite; making guesses regarding the order and internal harmony of the data observed and collocated; testing the hypotheses, not merely by the complete induction peculiar to mathematics, but, like his colleagues of the outer world, resorting also to experimental tests and incomplete induction; frequently finding it necessary, in view of unforeseen disclosures, to abandon one hopeful hypothesis or to transform it by retrenchment or by enlargement:—thus, in his own domain, matching, point for point, the processes, methods and experience familiar to the devotee of natural science.
In Lectures on Science, Philosophy and Art (1908), 26

A discovery is generally an unforeseen relation not included in theory.
From An Introduction to the Study of Experimental Medicine (1865), as translated by Henry Copley Greene (1957), 38.

An inventive age
Has wrought, if not with speed of magic, yet
To most strange issues. I have lived to mark
A new and unforeseen creation rise
From out the labours of a peaceful Land:
Wielding her potent enginery to frame
And to produce, with appetite as keen
As that of war, which rests not night or day.
In The Excursion (1814). In The Works of William: Wordsworth (1994), Book 8, 875.

Astronomy may be revolutionized more than any other field of science by observations from above the atmosphere. Study of the planets, the Sun, the stars, and the rarified matter in space should all be profoundly influenced by measurements from balloons, rockets, probes and satellites. ... In a new adventure of discovery no one can foretell what will be found, and it is probably safe to predict that the most important new discovery that will be made with flying telescopes will be quite unexpected and unforeseen. (1961)
Opening and closing of 'Flying Telescopes', Bulletin of the Atomic Scientists (May 1961), Vol. 17, No. 5, 191 and 194.

Ay, driven no more by passion's gale,
Nor impulse unforeseen,
Humanity shall faint and fail,
And on her ruins will prevail
The Conquering Machine!
Responsibility begone!
Let Freedom's flag be furled;
Oh, coming ages, hasten on,
And bring the true Automaton,
The monarch of the world.
'The Conquering Machine', Dreams to Sell (1887), 29-30.

I have always attached great importance to the manner in which an experiment is set up and conducted ... the experiment should be set up to open as many windows as possible on the unforeseen.
(1954). In Charles Coulston Gillespie (ed.), Dictionary of Scientific Biography (1973), Vol. 7, 153.

Ideologues of all persuasions think they know how the economy will respond to the Administration’s strange mixture of Lafferism and monetarism. Indeed, their self-confidence is so vast, and their ability to rationalize so crafty, that one cannot imagine a scenario for the next few years, that they would regard as falsifying their dogma. The failure of any prediction can always be blamed on quirky political decisions or unforeseen historical events.
In 'Mathematical Games: The Laffer Curve', Scientific American (Dec 1981), 245, No. 6, 30. Collected in The Night Is Large: Collected Essays, 1938-1995 (1997), 135.

Mathematicians attach great importance to the elegance of their methods and their results. This is not pure dilettantism. What is it indeed that gives us the feeling of elegance in a solution, in a demonstration? It is the harmony of the diverse parts, their symmetry, their happy balance; in a word it is all that introduces order, all that gives unity, that permits us to see clearly and to comprehend at once both the ensemble and the details. But this is exactly what yields great results, in fact the more we see this aggregate clearly and at a single glance, the better we perceive its analogies with other neighboring objects, consequently the more chances we have of divining the possible generalizations. Elegance may produce the feeling of the unforeseen by the unexpected meeting of objects we are not accustomed to bring together; there again it is fruitful, since it thus unveils for us kinships before unrecognized. It is fruitful even when it results only from the contrast between the simplicity of the means and the complexity of the problem set; it makes us then think of the reason for this contrast and very often makes us see that chance is not the reason; that it is to be found in some unexpected law. In a word, the feeling of mathematical elegance is only the satisfaction due to any adaptation of the solution to the needs of our mind, and it is because of this very adaptation that this solution can be for us an instrument. Consequently this esthetic satisfaction is bound up with the economy of thought.
In 'The Future of Mathematics', Monist, 20, 80. Translated from the French by George Bruce Halsted.

One must accept the results of experiments as they come, with all their unexpectedness and irregularity.
In An Introduction to the Study of Experimental Medicine (1927, 1957), 38, as translated by Henry Copley Greene. From the original French by Claude Bernard: “il faut accepter les résultats de l'expérience tels qu'ils se présentent, avec tout leur imprévu et leurs accidents.” (1865), 68. A Google translation gives: “One must accept the results of the experiment as they present themselves, with all their unforeseen and their accidents.”

Our stability is but balance, and wisdom lies
In masterful administration of the unforeseen.
In The Testament of Beauty (1929), Book 1, 1, lines 6-7.

We have here spoken of the prediction of facts of the same kind as those from which our rule was collected. But the evidence in favour of our induction is of a much higher and more forcible character when it enables us to explain and determine cases of a kind different from those which were contemplated in the formation of our hypothesis. The instances in which this has occurred, indeed, impress us with a conviction that the truth of our hypothesis is certain. No accident could give rise to such an extraordinary coincidence. No false supposition could, after being adjusted to one class of phenomena, so exactly represent a different class, when the agreement was unforeseen and contemplated. That rules springing from remote and unconnected quarters should thus leap to the same point, can only arise from that being where truth resides.
In The Philosophy of the Inductive Sciences (1840), Vol. 2, 230.

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
