One of the curious things about the history of philosophy is that it periodically throws up thinkers who question the whole business of… doing philosophy. How should we situate these paradoxical figures? Is it possible to be a philosopher if you're arguing that philosophy is an impossible project?

The project of bringing extinct animals back into being is sexy, hi-tech and could confer significant environmental benefits - but at what cost? Some argue that resurrecting extinct species could actually work against the conservation of threatened species that currently exist. Why worry about their possible extinction, if we can just bring them back?

Gene technology has brought us to the point where it's theoretically possible to bring back extinct animals from the "species grave". But the science is not straightforward - and neither is the philosophy.

This week we're exploring the idea that art can say things, and do things, and mean different things according to shifting historical circumstances - and that those sayings, doings and meanings aren't always benign or harmless. How should we respond to morally problematic art - particularly the kind of art that can function as hate speech?

Women have always been philosophers, often highly regarded by their male contemporaries. So why are women philosophers often regarded today as second-tier thinkers? And what happens when we try to uncover their histories?

Ninety-four per cent of Australians do not read privacy policies that apply to them – because who has the time? But the amount of data we all create and share has dramatic implications for privacy and safety. Informed consent is taken very seriously in the medical community, is it time for companies using AI and Big Data to follow suit?

If you don't know much about women philosophers in the ancient Graeco-Roman world, you have a good excuse. They're known to have existed, but hardly any of their works have survived, and historical accounts of their lives tend to come from biographies written by men. This week we try to unravel the mystery.

This week we're exploring the concept of moral creativity - a virtue that can be useful when it comes to negotiating the grey areas in our modern moral universe.

How can learning flourish in a time of war? Since the Russian invasion of Ukraine in January 2022, thousands of scholars have fled or been displaced, while nearly 200 institutions of higher education have been damaged or destroyed. This week we explore the possibilities for supporting and restoring the academy, and the role of Ukrainian intellectual traditions in resistance.

As much as we dislike thinking about it, failure is deeply embedded within everything we do and everything we are. From our politics to our bodies, the salient feature is that it all falls apart sooner or later. Failure has inspired a million depressing songs and poems - but it's also fertile ground for philosophy, and for some unexpectedly positive reflections.
