In our post truth age it seems that  we can collect beliefs on a whim or a tribal fashion. And many are happy to hold contradictory views to suit their temporary desires.  

Is this a dangerous approach that threatens not only the coherence of our own outlook but the stability and success of culture and society as whole?  Do we need to apply reason to sort wild opinion from truth, eradicate our hypocrisies and build a better society?  Or is the era of enlightenment reason over, and time to see its assertions as the prejudiced theories of a privileged class who used logic to promote a particular world view. 

Distinguished philosophy professor Graham Harman, author of Oughts and Thoughts Anandi Hattiangadi and post-post-realist Hilary Lawson explore the difference between opinion and truth.
