I'm currently reading
A Critical History of Western Philosophy, edited by D.J O'Connor. As the title suggests, this text is more critical than historical, but the authors give a good objective anaysis of whomever they are critiquing before they rip them apart. Thus far, the breadth and depth of this book, combined with its readability, is remarkable. I highly recommend it.
If you're more interested in understanding the discussions occuring in today's English speaking acadamies, then I'd recommend
100 Years of Philosophy, by John Passmore. This text is historical, not critical, and does a good job of tracing the problems that vexed the precursors of today's (mostly) analytical philosophers, and why and how these philosophers responded to the philosophical challenges of their day--setting up the problems and questions being dealt with now. Mr. Passmore also wrote an expansion covering "contemporary" philosophers, e.g. Carnap, Quine, Kripke, Dummett, etc., whose legacies are just starting to be felt.
Philosophical Foundation: A Critical Analysis of Basic Belief, by Surrendra Gangadean. This book is a critical examination of the assumptions in just about any popular worldview you can imagine. It's a great intro to both philosophy and religion. Everyone should read this book.
Finally,
The Clarity of God's Existence: the Ethics of Belief after the Enlightenment, by Owen Anderson. This is a must read for all theists, particularly Christian theists. However, this book isn't just for theists: "“The audience for this is anyone who is interested in questions about religious belief in the modern world,” says the author, who has received a grant from the Harvard Pluralism Project to study the religious diversity of the greater Phoenix area. “Are authors like Harris, Dawkins and Hitchens correct in challenging the validity of one’s belief in God? Do they successfully show that there is an excuse for unbelief, or even that there is no excuse for belief? My book looks at the many ways the need for clarity has been avoided, and how excuses have built up. I then suggest ways this might be addressed. For this reason, it should be of interest to both the believer and the non-believer.”"
