Professor Joseph Camilleri (pictured) has long believed in the power of conversation. He acted on that belief about three years ago and set up the Melbourne-based group, "Conversation at the Crossroads".

Here he talks about that group, and the power of conversation and alerts listeners to an upcoming series of six, weekly sessions entitled "Ethics in Turbulent Times: How to Bring Society to Higher Ground".

International thinker and philosopher, Peter Singer, will be among the guests - people can attend in person or virtually.

Conversation at the Crossroads secretary, Susan Lengel, was a guest on Climate Conversations in May this year.
