　　A short digression into model theory will help us to analyze the expressive power of the first-order language， and it will turn out that there are certain deficiencies. For example， the first-order language does not allow the formulation of an adequate axiom system for arithmetic or analysis. On the other hand， this di~culty can be overcome——-even in the framework of first-order logic——by developing mathematics in set-theoretic terms. We explain the prerequisites from set theory necessary for this purpose and then treat the subtle relation between logic and set theory in a thorough manner.
　　Godels incompleteness theorems are presented in connection with several related results (such as Trahtenbrots theorem) which all exemplify the limitatious of machine-oriented proof methods. The notions of computability theory that are relevant to this discussion are given in detail. The concept of computability is made precise by means of the register machine as a

内容简介

　　What is a mathematical proof? How can proofs be justified? Are there limitations to provability? To what extent can machines carry out mathematical proofs?
　　Only in this century has there been success in obtaining substantial and satisfactory answers. The present book contains a systematic discussion of these results. The investigations are centered around first-order logic. Our first goal is Godels completeness theorem， which shows that the consequence relation coincides with formal provability： By means of a calculus consisting of simple formal inference rules， one can obtain all consequences of a given axiom system (and in particular， imitate all mathematical proofs)

逻辑问题，初步奠定了数理逻辑的基础。

用数学的方法研究逻辑的系统思想一般追溯到莱布尼茨，他认为经典的传统逻辑必须改造和发展，使之更为精确和便于演算。后人基本是沿着莱布尼茨的思想进行工作的。

利用计算的方法来代替人们思维中的逻辑推理过程，这种想法早在十七世纪就有人提出过。莱布尼茨就曾经设想过能不能创造一种“通用的科学语言”，可以把推理过程象数学一样利用公式来进行计算，从而得出正确的结论。由于当时的社会条件，他的想法并没有实现。但是它的思想却是现代数理逻辑部分内容的萌芽，从这个意义上讲，莱布尼茨可以说是数理逻辑的先驱。
