This article explores a perplexing line from Rousseau's Emile: his suggestion that the "most important rule" for the educator is "not to gain time but to lose it." An analysis of what Rousseau meant by this line, the article argues, shows that Rousseau provides the philosophical groundwork for a radical critique of the contemporary cultural framework that supports homework, standardised testing, and the competitive extracurricular activities that consume children's time. He offers important insights to contemporary parents and educators wishing to reimagine an educational system that is currently fuelled more by familial and international amour propre than by children's interests and needs. Not the least of these is his recognition that to reimagine children's education would require a new configuration of the very terms of modern life. Problematically, however, Rousseau's alternative to mechanised clock-time depends on the labour of Sophie, whose time is also reconfigured. For the next generation of children to be educated according to natural time, Sophie's labour needs to be off the clock too, which is just as much a linchpin of her removal from the public sphere of citizenship and the paid workforce as it is of Emile's education for public life, or so the final section of this paper argues.
