“With his suave and unctuous prose, Latour presents the urbane face of post-modern irrationalism. How does he proceed? First, he reduces reason to discrimination: ‘‘Reason’ is applied to the work of allocating agreement and disagreement between words. It is a matter of taste and feeling, know-how and connoisseurship, class and status. We insult, frown, pout, clench our fists, enthuse, spit, sigh and dream. Who reasons?’ (2.1.8.4) Second, he reduces science to force: ‘Belief in the existence of science is the effect of exaggeration, injustice, asymmetry, ignorance, credulity, and denial. If ‘science’ is distinct from the rest, then it is the end result of a long line of coups de force’. (4.2.6.) Third, he reduces scientific knowledge (‘knowing-that’) to practical know-how: ‘There is no such thing as knowledge—what would it be? There is only know-how. In other words, there are crafts and trades. Despite all claims to the contrary, crafts hold the key to all knowledge. They make it possible to ‘return’ science to the networks from which it came’. (4.3.2.) Last but not least, he reduces truth to power: ‘The word ‘true’ is a supplement added to certain trials of strength to dazzle those who might still question them’. (4.5.8.) 17. It is instructive to note how many reductions must be carried out in order for irreductionism to get off the ground: reason, science, knowledge, truth—all must be eliminated. Of course, Latour has no qualms about reducing reason to arbitration, science to custom, knowledge to manipulation, or truth to force: the veritable object of his irreductionist afflatus is not reduction per se, in which he wantonly indulges, but explanation, and the cognitive privilege accorded to scientific explanation in particular. Once relieved of the constraints of cognitive rationality and the obligation to truth, metaphysics can forego the need for explanation and supplant the latter with a series of allusive metaphors whose cognitive import becomes a function of semantic resonance: ‘actor’, ‘ally’, ‘force’, ‘power’, ‘strength’, ‘resistance’, ‘network’: these are the master-metaphors of Latour’s irreductionist metaphysics, the ultimate ‘actants’ encapsulating the operations of every other actor”
