A who's who of philosophers are in Wollongong for one of the largest gatherings of its kind in the world.
And it's the second time in a decade that the University of Wollongong has hosted the prestigious Australasian Association of Philosophy Conference (July 7-11).
Philosophers from across Australia and around the world are set to deliver around 200 talks on a variety of subjects during the five-day conference.
Practical ethics, political philosophy, feminist philosophy, philosophy of mind and artificial intelligence are some of the topics to be discussed.
Conference organiser Dr Patrick McGivern, a senior lecturer in philosophy at UOW, said the conference was an opportunity for philosophers to engage in face-to-face discussions and to share and offer criticisms of arguments and ideas.
"We typically use conferences as testing grounds as we develop research. They allow us to refine our ideas and consider alternative perspectives," Dr McGivern said.
"Philosophers try to assess the assumptions underlying our ordinary understanding of many different problems, and often try to suggest new ways of thinking.
"The conference is also a fantastic opportunity for our students - undergraduate and postgraduate - to meet and interact with philosophers from around the world."
Wollongong last hosted the conference in 2012 and Dr McGivern said hosting it for the second time in a decade was a sign of the university's respected place in the Australasian philosophical community.
