摘要

The origins of this informative and important volume go back to a conference in Leeds and a workshop in Coim-bra that were both celebrating the 100th birthday of "one of the greatest logicians ever to whom we owe the most profound investigation of the nature of proofs since Aristotle and Frege". That's how the editors characterize Gerhard Gentzen in their Preface. Gentzen was born in 1909 three years after Kurt Godel and three years before Alan Turing. What a constellation of logical, mathematical and philosophical genius. Godel and Turing are widely known: Godel through his incompleteness theorems, the first of which establishes limits of formal provability, and Turing through his undecidability theorem, which crucially uses his profound analysis of computations (carried out by humans). Gentzen became famous through his consistency proof for arithmetic. Evaluating the significance of that proof is, however, a much more subtle task than judging the "negative" results of Godel and Turing, both with distinctive mathematical underpinnings and striking philosophical consequences. This subtlety is undoubtedly one part of the reason why Gentzen has not yet achieved the wide recognition of his contemporaries; another part is his direct involvement in the "failed" Hilbert Program. That's why I will describe also the program's emergence, its broad goals and the directions of contemporary work in its tradition.
