24. Peter Suber, "Kurt Gödel In Blue Hill" A brief account of kurt G¶del's trip to Blue Hill, Maine, in the summer of 1942, by Peter Suber. http://www.earlham.edu/~peters/writing/godel.htm

This essay originally appeared in the Ellsworth American , August 27, 1992, Section I, p. 2. Peter Suber Ellsworth American serves the Blue Hill area.) For this HTML version I restore the footnotes , which I did not submit to the newspaper, and a sidebar , which the newspaper omitted perhaps for being too technical. 50 Years Later, The Questions Remain Peter Suber Philosophy Department Earlham College The first incompleteness theorem showed that some perfectly well-formed arithmetical statements could never be proved true or false. Worse, it showed that some arithmetical truths could never be proved true. More precisely, for every axiomatic system designed to capture arithmetic, there will be arithmetic truths which cannot be derived from its axioms, even if we supplement the original set of axioms with an infinity of additional axioms. This shattered the assumption that every mathematical truth could eventually be proved true, and every falsehood disproved, if only enough time and ingenuity were spent on them. The second incompleteness theorem showed that axiomatic systems of arithmetic could only be proved consistent by other systems. This made the proof conditional on the consistency of the second system, which in turn could only be validated by a third, and so on. No consistency proof for arithmetic could be final, which meant that our confidence in arithmetic could never be perfect.

25. Homage To Kurt Godel. A quick sketch of godel's theorem http://www.chaos.org.uk/~eddy/math/Godel.html

The Berry Paradox (a cleaner variant on the `smallest non-interesting number' folly). could not be both consistent and complete; and could not prove itself consistent without proving itself inconsistent. The crucial technical terms of the discussion: Peano's axioms provide a formal description of the process of counting. They can be constructed in any logical system capable of the variety of counting in which any number has a successor - so that there is no `last' number - and distinct numbers have distinct successors. Consistency (of which the petty variety is the hobgoblin of small minds) is that desirable property of a logical system which says that there are no statements which the system regards as both true and false. Completeness is the desirable property of a logical system which says that it can prove, one way or the other, any statement that it knows how to address. ie it cannot be proven either true or false; in particular that it cannot be proven true. But `that it cannot be proven true' is Consequently, any logical system which can make up its mind about its consistency can prove itself inconsistent (provided it can count -

"In the early 1930's, Gödel had steadily advanced his knowledge in many areas of logic and mathematics. . . In the period 1932-1936 he published thirteen short but noteworthy papers in that journal on a variety of topics, including intuitionistic logic, the decision problem for the predicate calculus, geometry, and lengths of proofs. Some of the results in logic were to be of lasting interest" (Straus). Gödel provided the key theoretical concepts for modern general purpose digital computers.

Sigmund Freud Leo Baekeland Albert Einstein Alexander Fleming ... Tim Berners-Lee Mathematician He turned the lens of mathematics on itself and hit upon his famous "incompleteness theorem"driving a stake through the heart of formalism BY DOUGLAS HOFSTADTER The beauty of this mechanistic vision of mathematics was that it eliminated all need for thought or judgment. As long as the axioms were true statements and as long as the rules of inference were truth preserving, mathematics could not be derailed; falsehoods simply could never creep in. Truth was an automatic hereditary property of theoremhood. The set of symbols in which statements in formal systems were written generally included, for the sake of clarity, standard numerals, plus signs, parentheses and so forth, but they were not a necessary feature; statements could equally well be built out of icons representing plums, bananas, apples and oranges, or any utterly arbitrary set of chicken scratches, as long as a given chicken scratch always turned up in the proper places and only in such proper places. Mathematical statements in such systems were, it then became apparent, merely precisely structured patterns made up of arbitrary symbols.

This theorem is one of the most important proven in this century, ranking with Einstein's Theory of Relativity and Heisenberg's Uncertainty Principle. A related page with some interesting links is . You can also look at available on-line . It's also in print in a nice but inexpensive edition from Dover. Jones and Wilson, An Incomplete Education outside the system in order to come up with new rules an axioms, but by doing so you'll only create a larger system with its own unprovable statements. The implication is that all logical system of any complexity are, by definition, incomplete; each of them contains, at any given time, more true statements than it can possibly prove according to its own defining set of rules. Boyer, History of Mathematics Nagel and Newman, Principia , or any other system within which arithmetic can be developed, is essentially incomplete . In other words, given any consistent set of arithmetical axioms, there are true mathematical statements that cannot be derived from the set... Even if the axioms of arithmetic are augmented by an indefinite number of other true ones, there will always be further mathematical truths that are not formally derivable from the augmented set.
