Argument from precedent is a common argument in discussion, often used by committees or in meetings. It consists in saying that to act correctly in circumstances X would be inadvisable, in case others consider that this would set a precedent for acting in circumstances Y, where (it is argued) X and Y are superficially similar but (on close examination) are radically different. The Microcosmographia Academica, published in 1908, cited this as one of the reasons why "nothing should ever be done for the first time".
The fallacy is similar to the slippery slope argument.
Famous quotes containing the words argument, setting and/or precedent:
“Argument is conclusive ... but ... it does not remove doubt, so that the mind may rest in the sure knowledge of the truth, unless it finds it by the method of experiment.... For if any man who never saw fire proved by satisfactory arguments that fire burns ... his hearer’s mind would never be satisfied, nor would he avoid the fire until he put his hand in it ... that he might learn by experiment what argument taught.”
—Roger Bacon (c. 1214–1294)
“Teaching Black Studies, I find that students are quick to label a black person who has grown up in a predominantly white setting and attended similar schools as “not black enough.” ...Our concept of black experience has been too narrow and constricting.”
—bell hooks (b. c. 1955)
“I am heartily tired of this life of bondage, responsibility, and toil. I wish it was at an end.... We are both physically very healthy.... Our tempers are cheerful. We are social and popular. But it is one of our greatest comforts that the pledge not to take a second term relieves us from considering it. That was a lucky thing. It is a reform—or rather a precedent for a reform, which will be valuable.”
—Rutherford Birchard Hayes (1822–1893)
