Thick with heat and windows dripping with condensation, the atmosphere in and overcrowded Café Oto was almost tangible as I walked around the packed floor of eager participants looking to prop myself up against a vacant wall space. I found one at the back of the room and waited for the night to begin.

I was there for a marathon evening based on the work of philosopher Slavoj Žižek, and his latest book Less Than Nothing.  A non-stop 24-hour (yes, you read that correctly) event that began with a seminar by Iain Hamilton Grant before a talk by Žižek himself was then turned over to the general public who in turns read from the author’s latest offering throughout the night and next day. Frazzled from a particularly trying week at work, I didn’t quite manage the whole 24 hours.

I couldn’t and I’m not going to attempt to summarise Žižek’s lecture – you can listen to it yourself below - but there was something about the persistent heckling during this talk that made me think, not about the heckle itself but about what was going on in the room. About the public engaging with philosophy. Even though the man’s complaints were drowned out against the far more numerous groans of Žižek supporters that greeted it, it made me contemplate the possible role philosophy could and should have in society.

There is a possibly apocryphal interpretation of Socrates that says he used to sit in the Athenian square debating with the general public about the subject of philosophy. That this practice, for him, in someway constituted doing philosophy. That philosophy should really be about debating with everyday people and bringing academic subjects to the public as opposed to a conception of the subject in which philosophers sit alone in universities and think about philosophical problems. Fast-forward over 2,000 years and this debate about whether academic subjects should prioritise public engagement or research is - with universities having to justify funding against the backdrop of education cuts - as current as ever.

The tension between working in an academic environment and engaging the general public in those subjects was something familiar to me from my time studying philosophy. Throughout my studies at a BA and MA level I often wondered, ironically perhaps, what was the point of my chosen subject. Why was I doing philosophy and did it serve any purpose or public good? Over the course of four years I went from believing I was doing something useful to believing I was not. The further up the academic ladder I went – with the increasing specialisation and alienation from the general public this requires - the less I felt the academic work I was doing was a valuable public service. Writing a dissertation on objections related to a probabilistic account of subjunctive conditionals (yes, again you read that correctly) was the point I realised my time in the subject was up.

The Saturday previous to the Žižek talk, I’d been at a similar event. This time though at Kensington’s Institut Français and the My Night with Philosophers event – a vast assortment of lectures and talks comprising the audiovisual, written, musical and theatrical that took place through the night. Having drunk enough wine and coffee to power me through the 12 hours I fell into a twitchy sleep haunted by words such as subjunctives, truth, beauty, reality and all manner of other philosophical concepts. Spurred on by the amount of conversations about Descartes’ sceptic I’d heard the night before, when I awoke I even pinched myself to double check I was really awake. Although, as Descartes would say, this is no guarantee to know that I was really awake as opposed to just being tricked by some malicious demon.

As with the Žižek talk, people were actively engaged in philosophy. Over the course of the evening through readings, performances and most importantly arguing and debating with each other as well as the philosophers giving talks it was strikingly clear that there is not only a need but an appetite for this kind of public engagement of academic subjects. Particularly appealing for myslef was watching the philosophers debate between themselves (see here Beyond The Fringe’s fantastic spoof of such debates) and, in certain debates, try to find their own answers to the questions that had bothered me so much as a student and that I’ve outlined above. They didn’t reach any conclusive answers but then again, if I’d learned anything from studying philosophy and attending these events, it was that it isn’t the point of the subject. And maybe that’s why we need it.
