The following books outline an entire “worldview,” they talk argue for conclusions on a broad range of philosophical questions.
Philosophical Explanations by Robert Nozick – This is a book tackling the classic problems of philosophy: What is the self? Do we have free will? Why is there something rather than nothing? A brilliant book from a first rate philosopher.
Good and Real by Gary Drescher – Gary Drescher argues for a deterministic world, and argues free will, consciousness, and morality can thrive under such a worldview. I changed my position on ethics because of this book (I now hold to Drescher’s ‘Golden Rule Ethics’ instead of utilitarianism).
Sense and Goodness without God by Richard Carrier. Carrier’s classic summary of the naturalistic worldview. His short ‘n sweet discussions of the evidential arguments for atheism, how we can know the truth, and current scientific knowledge of the cosmos are sensible, logical and worth having.
The Atheists Guide to Reality by Alex Rosenberg. I reviewed this book earlier in the year, and while I think much of what the book says could be restated in a slightly less harsh way without compromising the book’s main ideas, I think at least some of Rosenberg’s ideas are sound, and I have the lurking suspicion that we may look back on this book as being a really important contribution to human knowledge.
