What does liberalism mean today?

Liberalism is one of the most influential — and contested — political philosophies of the modern age. But what does it actually mean in contemporary Australia? Is it a philosophy of individual freedom and limited government? A cultural attitude toward diversity and change? Or has it become something else entirely? A panel of practitioners and philosophers, current politicians and historical scholars explores liberalism as a set of political and cultural ideas, as a practical governing philosophy and as the ideological foundation of one of Australia's major political parties. Presented at the Malcolm Fraser Symposium by the Trinity College, University of Melbourne. Speakers David KempFormer minister for education in the Howard government, author of The Land of Dreams, a history of liberal and democratic ideas in Australia Sarah HendersonLiberal Senator for Victoria; former Shadow Minister for Education and Communications Alexandre LefebvreProfessor of politics and philosophy, University of Sydney.
