Last week, tragedy struck two institutions I love. Both of them are devoted to an idea I’m passionate about: freedom.

I speak of the Liberal Party of Australia and, of course, Fleetwood Mac.

I’m happy to confess I listen to Rumours, Fleetwood Mac’s most famous album, just about every week. Almost every song is about different ideas of liberty.

In ‘Dreams’ Stevie Nicks asks, ‘You say you want your freedom, well who am I to hold you down?’ It’s what philosophers like Isaiah Berlin called ‘negative freedom’.
