This 'book' is more of a pamphlet - it won't take you more than 20 minutes to 'read' through it. You don't have to agree wit everything the author says (for example, he is quite the Jesus freak but you can replace god/Jesus/the bible with whatever are the equivalent guiding/psi ritual principles/tools in your life), and if you keep and open mind you will likely have picked up a few nice tips and advises from the 40 some pages that have actual content. Add to that the fact that it is free, and that it provides some useful templates and lists, I'd say this ebooklet is definitely worth 20 minutes of your time. Honestly, in a world where 'ebooks' roughly around the quality of this are sold for $20+, I'd say that the author put this one out there for free alone should give you an incentive to at least take a look.
170 pages based on a worldview that others are born to live and die for us. The grossly inadequate and false information presented on subjects that the author knows nothing about undermines the credibility of the rest of the information.
Okay, habermas is hard. An 'introduction' to habermas which is accessible may be impossible. Given that, I think this book does a good job. It's only 110 pages, includes an interview w mr hab from which you can feel a bit of a human, and presents a decent amount if material. Of course, despite being an introduction it is full if jargon and it will be hard to read. But hey, that's kind of standard for any sociology book these days.
Surprisingly superficial. If this book was 128 pages of abou el fadl, it would have been much better. The quality of the 'replies' by various commentators ranges from good to wtf, and are severely limited by space.
