“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

Context: 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.

“Metaphysical principles are tempting shortcuts but not reliable guides. There are good reasons why things often seem to happen for reasons—and also reasons why that’s not a bedrock principle.”

“Consider what kind of authority [can be ascribed to] any principle which it open to us to choose to regard as authoritative or not. I may choose for example to observe a regimen of asceticism and fasting … for reasons of health … What authority such principles possess derives from the reasons for my choice. Insofar as they are good reasons, the principles have corresponding authority; insofar as they are not, the principles are to that same extent deprived of authority. It would follow that a principle for the choice of which no reasons could be given would be a principle devoid of authority. I might indeed adopt such a principle from whim or caprice or from some arbitrary purpose … but if I then chose to abandon the principle whenever it suited me, I would be entirely free to do so.”

“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 book Dark Age Ahead

Context: 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.

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

Marvin Minsky book Society of Mind

Source: The Society of Mind (1987), p. 187
Context: 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.
