God Argument [EPUB ebook] 
The Case Against Religion and for Humanism

There has been a bad-tempered quarrel between defenders and critics of religion in recent years. Both sides have expressed themselves acerbically because there is a very great deal at stake in the debate. This book thoroughly and calmly examines all the arguments and associated considerations offered in support of religious belief, and does so in full consciousness of the reasons people have for subscribing to religion, and the needs they seek to satisfy by doing so. And because it takes account of all the issues, its solutions carry great weight. The God Argument is the definitive examination of the issue, and a statement of the humanist outlook that recommends itself as the ethics of the genuinely reflective person.
