    If we are on the outside, we assume a conspiracy is the perfect working of a scheme. Silent nameless men with unadorned hearts. A conspiracy is everything that ordinary life is not. It's the inside game, cold, sure, undistracted, forever closed off to us. We are the flawed ones, the innocents, trying to make some rough sense of the daily jostle. Conspirators have a logic and a daring beyond our reach. All conspiracies are the same taut story of men who find coherence in some criminal act.


    The problem with that approach is there's no empirical evidence to support it actually works. So you're, in essence, warehousing kids in jail for a purpose you can't support by logic, science or in law.


    Now it is such a bizarrely improbable coincidence that anything so mind-bog-gglingly useful could have evolved purely by chance that some thinkers have chosen to see it as the final and clinching proof of the non-existence of God. The argument goes something like this I refuse to prove that I exist,' says God, for proof denies faith, and without faith I am nothing.'But,' says Man, The Babel fish is a dead giveaway, isn't it It could not have evolved by chance. It proves you exist, and so therefore, by your own arguments, you don't. QED.'Oh dear,' says God, I hadn't thought of that,' and promptly vanished in a puff of logic. Oh, that was easy,' says Man, and for an encore goes on to prove that black is white and getshimself killed on the next zebra crossing.

    I should make a distinction between two kinds of readjustment in the case of a conflict with experience, namely, between a change in the language, and a mere change in or addition of, a truth-value ascribed to an indeterminate statement (i.e. a statement whose truth value is not fixed by the rules of language, say by the postulates of logic, mathematics and physics). A change of the first kind constitutes a radical alteration, sometimes a revolution, and it occurs only at certain historically decisive points in the development of science. On the other hand, changes of the second kind occur every minute. A change of the first kind constitutes, strictly speaking, a transition from a language Ln into a new language Ln1.
