Well-written despite liberal bias
I've really enjoyed going through this history textbook. It is fascinating and well-written. It's laid out in a very orderly way and seems pretty thorough. I feel as though the authors made an honest attempt at being impartial, even though in reality it is impossible to be free of all bias. My understanding of American History is so much clearer now.
The authors do have a liberal worldview that permeates the second half of the book in particular. For example, the socialist idea that wealth should be possessed equally by all is taken for granted by the authors, and is repeatedly labeled "progress." They also portray the Socialists and Communists in a positive or (occasionally) neutral light. Such worldview presuppositions lie below the surface, so it took me a little while to catch them. They also disparage biblical mindsets about gender roles, etc. (and no, I'm not against women's suffrage, or anything like that!). I've found that oftentimes the facts stated may be true, but it's what is left out that causes a particular impression to be received.
With an awareness, however, of the philosophical presuppositions of the authors, I do think this book is well worth the read.
