On Randomness I (Trivia I)

“When a rule is extremely complex, that which conforms to it passes for irregular (random).” (Gottfried Leibniz, “Discourse on Metaphysics”, 1686)

“The tissue of the world is built from necessities and randomness; the intellect of men places itself between both and can control them; it considers the necessity and the reason of its existence; it knows how randomness can be managed, controlled, and used.” (Goethe)

“The very events which in their own nature appear most capricious and uncertain, and which in any individual case no attainable degree of knowledge would enable us to foresee, occur, when considerable numbers are taken into account, with a degree of regularity approaching to mathematical.” (John S Mills, “A System of Logic”, 1862)

“The definition of random in terms of a physical operation is notoriously without effect on the mathematical operations of statistical theory because so far as these mathematical operations are concerned random is purely and simply an undefined term.” (Walter A Shewhart and W. Edwards “Deming, Statistical Method from the Viewpoint of Quality Control”, 1939)

“Perhaps randomness is not merely an adequate description for complex causes that we cannot specify. Perhaps the world really works this way, and many events are uncaused in any conventional sense of the word.” (Stephen Jay Gould,"Hen's Teeth and Horse's Toes”, 1983).

“If you perceive the world as some place where things happen at random - random events over which you have sometimes very little control, sometimes fairly good control, but still random events - well, one has to be able to have some idea of how these things behave. […] People who are not used to statistics tend to see things in data - there are random fluctuations which can sometimes delude them - so you have to understand what can happen randomly and try to control whatever can be controlled. You have to expect that you are not going to get a clean-cut answer. So how do you interpret what you get? You do it by statistics.” (Lucien LeCam, [interview] 1988)

“Events may appear to us to be random, but this could be attributed to human ignorance about the details of the processes involved.” (Brain S Everitt, “Chance Rules”, 1999)

“While in theory randomness is an intrinsic property, in practice, randomness is incomplete information.” (Nassim N Taleb, “The Black Swan”, 2007)

“The fact that randomness requires a physical rather than a mathematical source is noted by almost everyone who writes on the subject, and yet the oddity of this situation is not much remarked.” (Brian Hayes, “Group Theory in the Bedroom”, 2008)

“Randomness might be defined in terms of order - its absence, that is. […] Everything we care about lies somewhere in the middle, where pattern and randomness interlace.” (James Gleick, “The Information: A History, a Theory, a Flood”, 2011)
