The final chapter 'What to Do', examines how the ideas of philosophy apply in our everyday lives, including the question of whether, if you are worrying about a problem, you should deal with the problem or simply try to stop worrying.
In a textbook the author might be expected to give an unbiased view of the material presented. This is not such a book - Blackburn is clearly arguing for his own views, and you may well find yourself disagreeing with them, in particular the parts on the mind and on religion. But that's good because it gives you something to help you in forming your own ideas. If you want to try to clarify your thoughts on some of the important philosophical questions then you're likely to find this book very useful.
