Is it a philosophy of individual freedom and limited government? A cultural attitude toward diversity and change? Or has it become something else entirely?

Or, is 'speaking across the fence' something writers and other creatives can offer us?"We're urged at all times — and for every occasion — to take a position. Yet is there a utility, both practical and ethical, in taking a breath, a pause, and refusing to land definitively on a stance?" — Christos TsiolkasSpeakerChristos TsiolkasAuthor of The Slap, The In Between, Barracuda, DamascusPlaywright and screenwriterFurther informationMore about the annual Ray Mathew Lecture, including the transcript and video of the 2025 lecture

Or is that an elite, outdated mission? Who gets to judge what knowledge is deemed useless or useful?
