H(D,D) computes the mapping from its finite string input to derive the behavior that it must report on. int sum(int x, int y) {return x + y; } sum(3,4) must provide the sum of 3+4 EVEN IF YOU EXPECT OTHERWISE. H(D,D) must provide that halt status of D correctly simulated by H EVEN IF YOU EXPECT OTHERWISE. You may believe in your mind that H(D,D) must report on the behavior of D(D) yet H(D,D) does not share this belief. There is no path from the input to H(D,D) by applying finite string transformation rules to the input to derived the behavior of D(D). >> The question that H computes IS NOT THE BEHAVIOR OF D(D).
