I have not read America The Philosophical by Carlin Romano. But I read a review of it by Peter Caws, a British American philosopher, who scoffs at the idea that America is philosophical.
I am thinking he is of a certain British character that only sees the crassness of America and thus can't see beyond his own bias, which can't see that it is really a hive of philosophical activity and experimentation. American is more philosophical than he thinks, perhaps the most philosophical nation in the world. Why he doesn't see this is because it is of an operational, gritty kind, not of the ivory tower nature he is accustomed to.
