“It is here that my parable differs from Hare’s. The partisan admits that many
things may and do count against his belief: whereas Hare’s lunatic who has a blik about
dons doesn’t admit that anything counts against his blik. Nothing can count against
bliks. Also the partisan has a reason for having in the first instance committed himself,
viz. the character of the Stranger; whereas the lunatic has no reason for his blik about
dons—because, of course, you can’t have reasons for bliks.”
