The disadvantage of a good non-fiction book is that I become deeply involved with it and need some quiet time to contemplate my reaction. That is hard to satisfy.
The solution, the perfect solution, turns out to be the Claremont Review of Books.
The Review is made up of dozens of short articles including essays and reviews. They are disproportionately pro-commerce and invariably intelligent.
The greatest benefit is that they are generally short. I can read it and think about it in small chunks of time such as an airplane flight or some time in the sun sitting on a porch between errands and parties.
I highly recommend the CRB.
I've been reading it for many years and have always been rewarded.
