4. Oriented towards a recipient: The sequence of symbols must beaddressed to or directed at somebody. (When a letter or a telegram is dispatched,<strong>the</strong> sender has a very definite recipient in mind; a book has a certainspecific readership; when a bee performs a food dance, importantinformation is conveyed to <strong>the</strong> o<strong>the</strong>r bees in <strong>the</strong> hive; DNA information istransferred to RNA which <strong>the</strong>n leads to protein syn<strong>the</strong>sis.) Recipient orientationis also involved even when <strong>the</strong>re is a captive audience in additionto <strong>the</strong> intended recipient (e.g. unintentional listening in to a conversationin a train compartment).Theorem A2: Random letter sequences or sequences produced by statisticalprocesses do not comprise information. Even if <strong>the</strong> informationcontent could be calculated according to Shannon’s <strong>the</strong>ory, <strong>the</strong> realnature of information is still ignored.<strong>In</strong> <strong>the</strong> historical debate in Oxford in 1860 between Samuel Wilberforce(1805 – 1873) and <strong>the</strong> Darwinist Thomas H. Huxley (1825 – 1895), <strong>the</strong>latter stated that, if monkeys should strum typewriters randomly for a longenough time, <strong>the</strong>n Psalm 23 would emerge sooner or later. Huxley usedthis argument to demonstrate that life could have originated by chance.But this question is easily resolved by means of <strong>the</strong> information <strong>the</strong>orems.It follows from <strong>the</strong> <strong>the</strong>orems mentioned in Chapter 4 and from TheoremA2 that information is not at all involved. The comparison invoked byHuxley has no bearing on information nor on life. The properties of informationdiscussed in Chapter 5, show that Huxley spoke about randomsequences, but information <strong>was</strong> not involved in this argument about monkeystyping. It is impossible for information to originate in matter by randomprocesses (see Theorem 1).Questions a) and b) raised above, can now be answered unambiguously:– It is only possible to syn<strong>the</strong>sise, by means of a statistical process, correctsentences obeying <strong>the</strong> conventions of a given language, if <strong>the</strong>required know-how is included beforehand in <strong>the</strong> data (valid morphemes,syllables, and words) and in <strong>the</strong> programs. These programsrequire enormous efforts, and it is <strong>the</strong>n even possible to generate sentenceswhich obey <strong>the</strong> syntactical rules of <strong>the</strong> language. But even ifsome meaning could be ascribed to a sequence of words obtained inthis way, it can still not be regarded as having “message quality”,because it originated in a random process.– Statistical processes cannot generate real information or real messages.205
