Part 3. Exercise
Challaging and deep reading . First of all, I would like to say in my behalf that I'm no logic expert, and that I had to cut Popper's book in chapter 8 just to read an introduction to Logic before I continue further in my personal experience with Popper. This book is a classical one, I had just seen references to it before, so I decided to give it a try. Boy, I was so out of my territory I felt really confused at times, but finally manage to get through the technical issues. This was a hard reading book for me, but I don't regret the month I devote to it, all the effort was worth it. So, why do I gave it four stars then? Well, just because it was hard, sorry, I don't have a better argument, but it's true, if you don't poses a solid background in Logic this would be a hard reading. I'm not going to talk much about this book content since I don't like that much, and everybody seems to do that, there's even some really good reviews in this page that make a better job that the one I could. Finally I will like to say that if you are interested in the philosophy behind scientific work, this is a wonderful book
Answer:
POS
