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.

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. Fiscal accountability is the principle that institutions collecting and disbursing taxes work most responsibly when they are transparent to those providing the money.

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.
