Impossible to find as otherness per se (obviously a dream); but at the same time---­ irreducible as a symbolic rule of the game, as a rule of the game that governs the world. The promiscuity and general confusion in which differences exist do not affect this rule of the game as such: it is not a rational law, nor is it a demonstrative process - we shall never have either metaphysical or scientific proof of this principle of foreignness and incomprehensibility: we simply have to accept it.The worst thing here is understanding, which is sentimental and useless.True knowledge is knowledge of exactly what we can never understand in the other, knowledge of what it is in the other that makes the other not oneself - and hence someone who can in no sense become separated from oneself, nor alienated by any look of ours, nor instituted by us in either identity or difference. (Never question others about their identity. In the case of America, the question of American identity was never at issue: the issue was America's foreignness.) If we do not understand the savage, it is for the same reason that he does not understand himself (the term 'savage' conveys this foreignness better than all later euphemisms).The rule of exoticism thus implies that one should not be fooled by understanding, by intimacy, by the country, by travel, by picturesqueness, or by oneself. The realm of radical exoticism, moreover, is not necessarily a function of travel: 'It is not essential, in order to feel the shock [of the exotic], to revive the old-fashioned episode of the voyage. [ ... ] The fact remains that such an episode and its setting are better than any other subterfuge for reaching this brutal, rapid and pitiless hand-to-hand conflict and making each blow count.' Travel is a subterfuge, then - but it is the most appropriate one of all. The Transparency of Evil: Essays in Extreme Phenomena
