Query: Frustrating

Have to agree with the review of The Ace of Knaves,but can only give this clumsy effort one star. That Kindle does not even list a category as PHILOSOPHY (but lots of trivial pop stuff such as "Teens" and "Romance" and "Sports and Outdoors")is indicative of the adolescent mentality which seems to dominate their editorial staff. That such a central philosophical work is ignored and mishandled is another sign that the ongoing effort to dumb down the American readership is still ongoing.
