‘But am I not compelled, then, to go the way I do in a chain of inferences?’—Compelled? After all I can presumably go as I choose! ‘But if you want to remain in accord with the rules you must go this way.’—Not at all, I call this “accord”.— ‘Then you have changed the meaning of the word “accord”, or the meaning of the rule’—No;—who says what “change” and “remaining the same” mean here?. … ‘But you surely can't suddenly make a (...) different application of the law now!’ … But if I simply reply: ‘Different?—But this surely isn't different!’—what will you do? That is: somebody may reply like a rational person and yet not be playing our game. (shrink)
