Pruning Quotes (7 quotes)
Common sense … may be thought of as a series of concepts and conceptual schemes which have proved highly satisfactory for the practical uses of mankind. Some of those concepts and conceptual schemes were carried over into science with only a little pruning and whittling and for a long time proved useful. As the recent revolutions in physics indicate, however, many errors can be made by failure to examine carefully just how common sense ideas should be defined in terms of what the experimenter plans to do.
In Science and Common Sense (1951), 32-33.
Dr. Johnson ... sometimes employed himself in chymistry, sometimes in watering and pruning a vine, and sometimes in small experiments, at which those who may smile, should recollect that there are moments which admit of being soothed only by trifles.
Quoted in James Boswell, The Life of Samuel Johnson, LL.D. (1826), Vol. 3, 352.
I have always liked horticulturists, people who make their living from orchards and gardens, whose hands are familiar with the feel of the bark, whose eyes are trained to distinguish the different varieties, who have a form memory. Their brains are not forever dealing with vague abstractions; they are satisfied with the romance which the seasons bring with them, and have the patience and fortitude to gamble their lives and fortunes in an industry which requires infinite patience, which raise hopes each spring and too often dashes them to pieces in fall. They are always conscious of sun and wind and rain; must always be alert lest they lose the chance of ploughing at the right moment, pruning at the right time, circumventing the attacks of insects and fungus diseases by quick decision and prompt action. They are manufacturers of a high order, whose business requires not only intelligence of a practical character, but necessitates an instinct for industry which is different from that required by the city dweller always within sight of other people and the sound of their voices. The successful horticulturist spends much time alone among his trees, away from the constant chatter of human beings.

When the 1880s began. Maxwell’s theory was virtually a trackless jungle. By the second half of the decade, guided by the principle of energy flow. Poynting, FitzGerald, and above all Heaviside had succeeded in taming and pruning that jungle and in rendering it almost civilized.
