Great picks. I started Coddling this week - I've learnt so much already. Incredibly insightful. Haidt's Happiness Hypothesis was the best book I'd read in a while, also highly recommended. It's about much more than just happiness, but how our mind/self/consciousness/emotions work.

Escape from Freedom (also known as Fear of Freedom) is great, as are a lot of Fromm's books. He's my favourite psychologist, and by a long way favourite Frankfurt School writer. I also love Man for Himself, The Sane Society, To Have or To Be, The Art of Loving. He's wonderfully BS-free, combining insights into psychology, society, work, politics etc.
