Policy-making, as exemplified by biotechnology policy, can be understo
od as an attempt to manage a field of discursivity, to construct regul
arity in a dispersed multitude of combinable elements. Following this
perspective of politics as a textual process, the paper interprets the
politicization of genetic engineering in Germany as a defence of the
political as a regime of heterogeneity, as a field of 'dissensus' rath
er than 'consensus', and a rejection of the idea that the framing of t
echnological transformation is an autonomous process. From its beginni
ngs in the early 1970s, genetic engineering was symbolically entrenche
d as a key technology of the future, and as an integral element of the
German politics of modernization. Attempts by new social movements an
d the Green Party to displace the egalitarian imaginary of democratic
discourse into the politics of genetic engineering were construed by t
he political elites as an attack on the political order of post-World
War II Germany. The 1990 Genetic Engineering Law attempted a closure o
f this controversy. But it is precisely the homogenizing idiom of this
'settlement' which continues to nourish the social movements and thei
r radical challenge to the definitions and codings of the politics of
genetic engineering.
