“The theory of chance consists in reducing all the events of the same kind to a certain number of cases equally possible”

—  Pierre-Simon Laplace , book Philosophical Essay on Probabilities

Philosophical Essay on Probabilities (1902)
Context: The theory of chance consists in reducing all the events of the same kind to a certain number of cases equally possible, that is to say, to such as we may be equally undecided about in regard to their existence, and in determining the number of cases favorable to the event whose probability is sought.<!--p.6

“If there can be agreement that certain rights are essential to reduce the chances of perfect injustice, that constitutes the beginning of a solid theory of rights.”

“A distinguished writer (Siméon Denis Poisson) has thus stated the fundamental definitions of the science:
:"The probability of an event is the reason we have to believe that it has taken place, or that it will take place."
:"The measure of the probability of an event is the ratio of the number of cases favourable to that event, to the total number of cases favourable or contrary, and all equally possible" (equally like to happen).
From these definitions it follows that the word probability, in its mathematical acceptation, has reference to the state of our knowledge of the circumstances under which an event may happen or fail. With the degree of information which we possess concerning the circumstances of an event, the reason we have to think that it will occur, or, to use a single term, our expectation of it, will vary.”

“Equally possible cases do not always exist, e. g, they are not present in the game with a biased die, or in life insurance. Strictly speaking, the propositions of the classical theory are therefore no applicable to these cases.”

“The first Part. Of the Definitions of the Dismes. The first Definition. Disme is a kind of Arithmeticke, invented by the tenth progression, consisting in Characters of Cyphers; whereby a certaine number is described, and by which also all accounts which happen in humane affayres, are dispatched by whole numbers, without fractions or broken numbers.”

Context: At various stages of evolution, the Indian cultures were presented with only a limited number of possibilities. The members of certain kinds of societies—the small band, the large band, the tribe, the chiefdom, the state, and variations of these—tended to make characteristic choices concerning religion, law, government, and art... Such choices were not... consciously made... For a particular society, they either worked or they did not work.<!-- p. 212

“In a free Government, the security for civil rights must be the same as that for religious rights. It consists in the one case in the multiplicity of interests, and in the other in the multiplicity of sects. The degree of security in both cases, will depend on the number of interests and sects; and this may be presumed to depend on the extent of country and number of People comprehended under the same Government.”

“The spinor genus is due to Eichler. His early results (1952) established the theory over the rational field and also, in certain special cases, over a number field. Kneser (1956) extended this to number fields in general. At about the same time Watson obtained Eichler's results by elementary methods over the rational field.”

“All novelty involves some degree of risk. The vast majority of biological mutations are said to be harmful. When, as in human affairs, enormous numbers of random possibilities are eliminated by rational choice, the chances of harm rather than good resulting are reduced, not eliminated.”

“True science consists in systematically examining all possible cases. Exact political economy has not achieved this until now. It does not even encompass all actual cases. This is one of the reason why exact theory finds itself in opposition to the historical school and why it does not have an awful lot to say to those economists who occupy themselves with issues of practical interest, theories of crisis, cartels and trusts.”
