“In the fields of observation chance favours only the prepared mind.”
Dans les champs de l'observation le hasard ne favorise que les esprits préparés.

Where observation is concerned, chance favors only the prepared mind.

General Quotes
Let an observer B on the star estimate the distance and epoch of the nova outburst to be x<nowiki>'</nowiki> units of length and t<nowiki>'</nowiki> units of time, respectively. Then the Lorentz formulae, relating x<nowiki>'</nowiki> to t<nowiki>'</nowiki>, are<center><math>x' = \frac {x-vt}{\sqrt{1-\frac{v^2}{c^2}}} ; \qquad t' = \frac {t-\frac{vx}{c^2}}{\sqrt{1-\frac{v^2}{c^2}}}</math></center>
These formulae are... quite general, applying to any event in line with two uniformly moving observers. If we let c become infinite then the ratio of v to c tends to zero and the formulae become<center><math>x' = x - vt ; \qquad t' = t</math></center>.

Context: In the new pattern of thought we do not assume any longer the detached observer, occurring in the idealizations of this classical type of theory, but an observer who by his indeterminable effects creates a new situation, theoretically described as a new state of the observed system. In this way every observation is a singling out of a particular factual result, here and now, from the theoretical possibilities, therefore making obvious the discontinuous aspect of physical phenomena.
Nevertheless, there remains still in the new kind of theory an objective reality, inasmuch as these theories deny any possibility for the observer to influence the result of a measurement, once the experimental arrangement is chosen. Therefore particular qualities of an individual observer do not enter into the conceptual framework of the theory.

Context: All savages seem to us alike as the trees of the distant forest. Here and there one unites in his own person, all the excellencies, and becomes the favourable representative of the whole, the image of savage greatness, the one grand character in which all others are lost to history or observation. Cornstalk possessed all the elements of savage greatness, oratory, statesmanship and heroism, with beauty of person and strength of frame. In appearance he was majestic, in manners easy and winning. Of his oratory, Colonel Benjamin Wilson, Senr., an officer in Dunmore's army, in 1774, having heard the grand speech to Dunmore in Camp Charlotte, says — "I have heard the first orators in Virginia, Patrick Henry, Richard Henry Lee, but never have I heard one whose powers of delivery surpassed those of Cornstalk on that occasion." Of his statesmanship and bravery there is ample evidence both in the fact that he was chosen head of the Confederacy, and in the manner he conducted the war of 1774, and particularly by his directions of the battle at Point Pleasant.

Context: Correct and accurate conclusions may be arrived at if we carefully observe the relation of the spheres of concepts, and only conclude that one sphere is contained in a third sphere, when we have clearly seen that this first sphere is contained in a second, which in its turn is contained in the third. On the other hand, the art of sophistry lies in casting only a superficial glance at the relations of the spheres of the concepts, and then manipulating these relations to suit our purposes, generally in the following way: — When the sphere of an observed concept lies partly within that of another concept, and partly within a third altogether different sphere, we treat it as if it lay entirely within the one or the other, as may suit our purpose.
