 Conservatives reject revolutionary Jacobinism’s espousal of political rationalism, which attempts to reconstruct society from abstract principles or general blueprint, without reference to tradition. Conservatives view society not as a machine but as a highly complex organism, and hold therefore that “without the aid of experience, reason cannot prescribe political ideals that can be realised in practice” (Beiser 1992: 283). Present generations possess duties and responsibilities whose original reasons, if they were ever apparent, are now lost. Tradition represents for conservatives a continuum enmeshing the individual and social, and is immune to reasoned critique; the radical intellectual is therefore arrogant and dangerous (Kekes 1997: 365). For liberals and socialists, in contrast, tradition has value only insofar as it survives rational criticism.
