5 The Retreat to Commitment, p. 91. This objection was, of course, already well known. ‘So rationalism is necessarily far from comprehensive or self-contained. This has frequently been overlooked by rationalists who thus exposed themselves to a beating in their own field and by their own favourite weapon whenever an irrationalist took the trouble to turn it against them’ (Popper K. R., The Open Society, 4th ed., 1962, p. 231).
6 This is not a quotation; see Bartley , op. cit., ch. iv, § 1.
7 This is my precis of the following passage:
‘The new framework permits a rationalist to be characterized as one who holds all beliefs, including his most fundamental standards and his basic philosophical position itself, open to criticism; who never cuts off an argument by resorting to faith or irrational commitment to justify some belief that has been under severe critical fire. I shall call this conception comprehensively critical rationalism’ (Hartley , op. cit., p. 146, italics his).
10 ‘… the practice of critical argument can be criticized without paradox, contradiction, or any other logical difficulty’ (op. cit., p. 149).
11 Op. cit., p. 148, italics in the original.
13 See his discussion of what he calls ‘the check of the problem’ (op. cit., pp. 159–161); here, the critic raises such methodological questions about a proposed theory as: ‘Does it solve the problems it was intended to solve? Or does it merely shift the problem? Does it solve the problem better than competing views? Or does it create still worse difficulties?’ (p. 160).
14 Why ‘irrationalist’? Is anyone who ventures to criticise CCR an irrationalist?
