This article is concerned with how the idea of anachronism can interfere with our thinking about social justice, peace, and human liberation. In the case of Israel/Palestine the idea of anachronism is deployed among liberals, progressives and radical theorists, and activists seeking peace and social justice who express animosity toward religiously motivated settlers and their settlement project. One of the ways in which they differentiate themselves from these settlers is by suggesting that settler actions belong to the past. They also (...) pity Palestinians conceived of as stuck in an oppressive system of settler colonialism that also belongs to the past, preventing them from moving forward. Both perceptions of anachronism limit the ways we can think about human liberation and peace. This article sheds light on a conundrum about who or what belongs to the past, and how thinking in such terms can contribute to the production of a particular moral collective and to the production of enmity. Both perceptions of anachronism frame history as a kind of progress in which peoples or groups might be ranked according to their levels of civilizational attainment, an idea we abandoned long ago as an analytical tool, but seem to have retained as a matter of practical political sympathy and judgment. This temporal conditioning can interfere with the thinking of even some of the most progressive social theorists, and mimics a colonial impulse. (shrink)
