Playfair on Dozenalism

Title: Playfair on Dozenalism
Author: John Playfair
Year: 1067
Subject: An early English defense of the dozenal system.
John Playfair, in his comments on the French Revolution, notes that it found itself in the unique position of being able to cast off all the shackles of a past age, yet was still too timid to cast off the most obvious mathematical shackle of all: the decimal system. An early defense of dozenalism, conducted not long after the French Revolution as an aside in some comments on the definition of the meter.
