„There is no reason why an extraphysical general principle is necessarily to be avoided, since such principles could conceivably serve as useful working hypotheses.“

—  David Bohm

Contexto: There is no reason why an extraphysical general principle is necessarily to be avoided, since such principles could conceivably serve as useful working hypotheses. For the history of scientific research is full of examples in which it was very fruitful indeed to assume that certain objects or elements might be real, long before any procedures were known which would permit them to be observed directly.

„Subsidiarity is the principle that government works best — most responsibly and responsively — when it is closest to the people it serves and the needs it addresses.“

—  Jane Jacobs, livro Dark Age Ahead

Contexto: Subsidiarity is the principle that government works best — most responsibly and responsively — when it is closest to the people it serves and the needs it addresses. Fiscal accountability is the principle that institutions collecting and disbursing taxes work most responsibly when they are transparent to those providing the money.

„For generations, scientists and philosophers have tried to explain ordinary reasoning in terms of logical principles — with virtually no success.“

—  Marvin Minsky, livro Society of Mind

Fonte: The Society of Mind (1987), p. 187
Contexto: For generations, scientists and philosophers have tried to explain ordinary reasoning in terms of logical principles — with virtually no success. I suspect this enterprise failed because it was looking in the wrong direction: common sense works so well not because it is an approximation of logic; logic is only a small part of our great accumulation of different, useful ways to chain things together.

„His majesty could not see why the principle was not applicable to politics. He resolved to try it.“

—  Alexander Bryan Johnson United States philosopher and banker 1786 - 1867

The Philosophical Emperor, a Political Experiment, or, The Progress of a False Position: (1841)
Contexto: His majesty recollected the celebrated quack doctor, who when asked why his patrons were more numerous than those of regular practitioners, replied, that he was patronised by the fools, who are numerous in every community, while regular physicians are patronised by the wise, who are few. His majesty could not see why the principle was not applicable to politics. He resolved to try it. He would so govern as to be patronised by the numerous class, and leave the desires of the few to be regarded by some future emperor, who should choose to make so unpromising an experiment.

„The general principles on which the fathers achieved independence, were … the general principles of Christianity, in which all those sects were united, and the general principles of English and American liberty, in which all those young men united, and which had united all parties in America, in majorities sufficient to assert and maintain her independence.“

—  John Adams 2nd President of the United States 1735 - 1826

Letter to Thomas Jefferson, 28 June 1813. Often misquoted as "The general principles on which the fathers achieved independence were the general principles of Christianity"
1810s
Contexto: The general principles on which the fathers achieved independence, were … the general principles of Christianity, in which all those sects were united, and the general principles of English and American liberty, in which all those young men united, and which had united all parties in America, in majorities sufficient to assert and maintain her independence. Now I will avow, that I then believed and now believe that those general principles of Christianity are as eternal and immutable as the existence and attributes of God; and that those principles of liberty are as unalterable as human nature and our terrestrial, mundane system.
