Neo-Luddism or new Luddism is a philosophy opposing many forms of modern technology. The term Luddite is generally used as a pejorative applied to people showing technophobic leanings. The name is based on the historical legacy of the English Luddites, who were active between 1811 and 1816. Neo-Luddism is a leaderless movement of non-affiliated groups who resist modern technologies and dictate a return of some or all technologies to a more primitive level. Neo-Luddites are characterized by one or more of the following practices: passively abandoning the use of technology, harming those who produce technology harmful to the environment, advocating simple living, or sabotaging technology. The modern neo-Luddite movement has connections with the anti-globalization movement, anarcho-primitivism, radical environmentalism, and deep ecology. Neo-Luddism is based on the concern of the technological impact on individuals, their communities, and/or the environment, Neo-Luddism stipulates the use of the precautionary principle for all new technologies, insisting that technologies be proven safe before adoption, due to the unknown effects that new technologies might inspire. Neo-Luddism distinguishes itself from the philosophy originally associated with Luddism in that Luddism opposes all forms of technology, whereas neo-Luddism only opposes technology deemed destructive or otherwise detrimental to society. Philosophy Neo-Luddism calls for slowing or stopping the development of new technologies. Neo-Luddism prescribes a lifestyle that abandons specific technologies, because of its belief that this is the best prospect for the future. As Robin and Webster put it, "a return to nature and what are imagined as more natural communities." In the place of industrial capitalism, neo-Luddism prescribes small-scale agricultural communities such as those of the Amish and the Chipko movement in Nepal and India as models for the future. Neo-Luddism denies the ability of any new technology to solve current problems, such as environmental degradation, nuclear warfare and biological weapons, without creating more, potentially dangerous problems. In 1990, attempting to found a unified movement and reclaim the term 'Luddite', Chellis Glendinning published her "Notes towards a Neo-Luddite manifesto". In this paper, Glendinning describes neo-Luddites as "20th century citizens—activists, workers, neighbors, social critics, and scholars—who question the predominant modern worldview, which preaches that unbridled technology represents progress." Glendinning voices an opposition to technologies that she deems destructive to communities or are materialistic and rationalistic. She proposes that technology encourages biases, and therefore should question if technologies have been created for specific interests, to perpetuate their specific values including short-term efficiency, ease
