That's How I Believe

'I suppose they try and make you believe an awful lot of nonsense?'
'Is it nonsense?  I wish it were.  It sometimes sounds terribly sensible to me.'
'But, my dear Sebastian, you can't seriously believe it all.'
'Can't I?'
'I mean about Christmas and the star and the three kings and the ox and the ass.'
'Oh yes, I believe that. It's a lovely idea.'
'But you can't believe things because they are a lovely idea.'
'But I do.  That's how I believe.'

-- Evelyn Waugh, Brideshead Revisited
