Recursive definitions are familiar in mathematics. For instance, the function f defined by f(0) = 1, f(1) = 1, f(x + 2) = f(x + 1) + f(x), gives the Fibonacci sequence: 1, 1, 2, 3, 5, 8, 13,.... (The study of difference equations concerns the problem of going from recursive definitions to algebraic definitions. The Fibonacci sequence is give by the algebraic definition 5 (1 + 5) x+1 5 (1 5) x+1.) f(x) = 5 2 5 2 The primitive recursive functions are an example of a broad and interesting class of functions that cam be obtained by such a formal characterization. Definition The class of primitive recursive functions is the smallest class C (i.e., intersection of all classes C) of functions such that i. All constant functions, λx 1 x 2 x k [m] are in C, 1 k, 0 m; ii. The successor function, λx[x + 1], is in C; iii. All identity functions, λx 1 x k [x i ] are in C, 1 i k; iv. If f is a function of k variables in C, and g 1, g 2,..., g k are (each) functions of m variables in C, then the function λx 1 x m [f(g 1 (x 1,..., x m ),..., g k (x 1,..., x m ))] is in C, 1 k, m; v. If h is a function of k + 1 variables in C, and g is a function of k 1 variables in C, then the unique function f of k variables satisfying f(0, x 2,..., x k ) = g(x 2,..., x k ), f(y + 1, x 2,..., x k ) = h(y, f(y, x 2,..., x k ), x 2,..., x k ) is in C, 1 k. (For (v), function of zero variables in C is taken to mean a fixed integer.)

At first sight it must seem intolerably degrading for Zen however the reader may understand this word to be associated with anything so mundane as archery. Even if he were willing to make a big concession, and to find archery distinguished as an art, he would scarcely feel inclined to look behind this art for anything more than a decidedly sporting form of prowess. He therefore expects to be told something about the amazing feats of Japanese trick-artists who have the advantage of being able to rely on a time-honored and unbroken tradition in the use of bow and arrow. For in the Far East it is only a few generations since the old means of combat were replaced by modern weapons, and familiarity in the handling of them by no means fell into disuse, but went on propagating itself, and has since been cultivated in ever widening circles. Might one not expect, therefore, a description of the special ways in which archery is pursued today as a national sport in Japan? Nothing could be more mistaken than this expectation. By archery in the traditional sense, which he esteems as an art and honors as a national heritage, the Japanese does not understand a sport but, strange as this may sound at first, a religious ritual. And consequently, by the art of archery he does not mean the ability of the sportsman, which can be controlled, more or less, by bodily exercises, but an ability whose origin is to be sought in spiritual exercises and whose aim consists in hitting a spiritual goal, so that fundamentally the marksman aims at himself and may even succeed in hitting himself.
