From someone who knew a thing or two about being a politician.
"Compassion is something individual and voluntary. You cannot compel somebody to be compassionate; nor can you be vicariously compassionate by compelling somebody else. The Good Samaritan would have lost all merit if a Roman soldier were standing by the road with a drawn sword, telling him to get on with it and look after the injured stranger. Because there can be no such thing as compulsory compassion or vicarious compassion, therefore it is a humbugging abuse of language, intended to deceive, to talk about a 'compassionate Government' or a 'compassionate party'—or even a 'compassionate society', unless one simply means by that a society which happens to contain a lot of compassionate individuals. Nor let anyone protest: 'Oh, but when I vote for a party which will "make provision on an unprecedented scale for those in need of help", it means I too shall have to pay my whack and so I am being compassionate after all'. Nonsense! The purpose of your vote is not to make yourself subscribe—that you can freely do at any time—but to compel others."
