Abstract

This article explores how the pre-eminent public psychology of the French Revolution – sentimentalism – shaped the necessity, understanding and construction of its most iconic public machine. The guillotine provided a solution to the problem of public executions in an age of both sentiment and reason. It was designed to rationalize punishment and make it more humane; but it was also designed to guard against the psychological effects of older, more variable and unpredictable methods of public execution on a sentimental public. That public, contemporaries argued, required executions performed by an unfailing technology. Rather than focus on the role of the guillotine after 1793, the article explores how the implacable mechanical action that helped produce the Reign of Terror and multiply the cadavers of medical science was demanded by the guillotine’s origins as a sentimental machine.
