„There are here two assumptions about 'evaluations ', which I will call assumption (1) and assumption (2). Assumption (1) is that some individual may, without logical error, base his beliefs about matters of value entirely on premises which no one else would recognise as giving any evidence at all. Assumption (2) is that, given the kind of statement which other people regard as evidence for an evaluative conclusion, he may refuse to draw the conclusion because this does not count as evidence for him.“

„Many of the words and numbers bandied by Obama and his administration may reflect an honest belief that the world is whatever well-intentioned people like them say about it. So, Obama's critics should reconsider their assumption that he is cynical. It is his sincerity that is scary.“
