ABSTRACT
It is clear that this position is abandoned by Samuelson in his 1950 interpretation. Here he states unequivocally that the question of integrability was a legitimate concern in the context of his new approach and, moreover, that it was not dealt with satisfactorily in the earlier paper (1950b, p. 370):
I soon realized that this [the ‘weak axiom’] could carry us almost all the way along the path of providing new foundations for utility theory. But not quite all the way. The problem of integrability, it soon became obvious, could not yield to this weak axiom alone.
