Die Entstehung neuer Erbeigenschaften,en collection of “primitive” statements is enlarged by combining statements. The Propositional Calculus does not analyse the original primitive statements. Our aim now is to construct a more complicated model of mathematical reasoning, which incorporates more of the ordinary features of this reasoning.

Die Entstehung neuer Erbeigenschaften,onstructed within the first-order predicate calculus will be called a first-order theory. By comparing a first-order theory with the informal theory on which it is modelled, we may gain insight into the influence of our logical system on our mathematics.

E. Blanck,F. Giesecke,H. Stremme N.. Accordingly, in order to show that a particular function .:N. → N is recursive, we must construct a Turing machine which computes .. This is a tiresome process, even for functions of relatively simple form, and consequently it is natural to seek an alternative characterisation of recursive functions that will facilitate their recognition.

Universal Algebra,nsisting of sets with certain operations satisfying certain conditions. The reader will also be aware that ideas and theorems, useful for the study of one type of system, can frequently be adapted to other related systems by making the obvious necessary modifications.
