When the largest companies in the world have corporate mottos like "Don't be evil" and politics splits the country into parties incredulous how the other side can even think as they do, it's maybe time to teach a bit more philosophy in schools and a bit less Shakespeare (Will should stay, just make room).
The book looks interesting. But the author runs the risk of swinging too far and suggesting too broad a definition for philosophy from its current narrow, useless pedestal in academia.
If philosophy is best regarded as "a universal human activity with many distinct cultural inflections" what does that mean?
Look what happened to art, anything and everything from a Rembrandt painting exhibition to your local hippy spoken word poetry slam is an art event? Wha? Art has lost some of its potential when it becomes that overwhelmingly big and confusing.
Defining what philosophy is (and isn't) and what it offers, seems like a really difficult and important first step before you can sell it to others. It's not clear if the author does this.
