Big Ideas

Harvard psychologist and bestselling author Steven Pinker is a fierce advocate for intellectual and academic freedom — and one of the world’s most prominent and provocative thinkers about human language, the mind, and how societies work. He joins Big Ideas host Natasha Mitchell with an 800-strong Melbourne audience to discuss his latest book When Everyone Knows That Everyone Knows: Common Knowledge and the Science of Harmony, Hypocrisy and Outrage. Steven Pinker doesn’t shy away from controversy — amidst the Trump administration's attacks on his own university he recently penned a NYT piece titled Harvard Derangement Syndrome — challenging the cancellation, character assassination and censorship of scholars who investigate controversial ideas.

In its second term, the Albanese Government enjoys a large majority in parliament and an opposition in disarray. But faced with a fragmented, fractious electorate, ever more entrenched inequality at home and volatility abroad, and with an emphasis on a stable and moderate governing style, is this government making the most of its political advantages? Does Labor still have the courage to take on the good fight?

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.
