of the work. Mobility of the individual between various groups and even sections according to personal desires was to be allowed. Fundamental to the Fourierian ideal was the notion of collective living and the rational performance of domestic duties. Individual households were seen as both wasteful in terms of duplicated effort performed and isolating of individuals—standing in the way of true cooperation and social harmony. Remaining in unpublished manuscript form until 1967 were Fourier's imaginative predictions about degrees of sexual promiscuity and the institutions and moral codes that would emerge to govern love and interpersonal relationships in the harmonious world of Compound Association. Role of force The Fourierian system of associations was based on voluntary participation and expansion through the force of example. Once founded, associations would demonstrate their practical merits and inspire emulation, with the first model communities replicating and spreading from localities to regions to nations and internationally. Never in his writings does Fourier appeal to governmental legislation or coercive power of any sort, instead believing association to be a natural and wholly voluntary structure, part of a Divine Social Code. Moreover, the achievement on an international scale would eliminate war. Instead, industrial armies would form to engage in gigantic reclamation projects, irrigating deserts, restoring vegetation, draining marshes and cultivating the land. The elimination of disease would follow, as such banes as cholera, typhus, and yellow fever would vanish with the unhealthful places whence they originated before society's restorative efforts. Through the planting of vast swaths of timber, cropland would be protected and the earth's climate would be slowly transformed, Fourier believed. Fantastic theories Fourier's theoretical system, described by one scholar as "vast and eccentric", was only part of the output of what another called "a most riotous and unpruned imagination". Fourier believed that in the new world people would live for 144 years, that new species of friendly and pacifistic animals such as "anti-lions" would emerge, and that over time human beings would develop long and useful tails. Fourier also professed a belief in the ability of human souls to migrate between physical and "aromal" worlds. Such thinking was set aside during the last 15 years of Fourier's life, when he instead began to concentrate on testing his economic and social ideas. Fourier's disciples, including Albert Brisbane and Victor Considerant, later pared down his writings into a comprehensible system for economic and social organization, with the Fourierist
