My rating: 4 of 5 stars
This book is a classic of twentieth century epistemology and the philosophy of science and must-read for anyone interested in those subjects. I also recommend this book for anyone interested in the development of knowledge as well as social justice within a democratic setting. Popper’s thesis is that the truth of any given matter is not obvious due to the limitations of human perception and reasoning and that, with this in mind, we should approach the process of observing and understanding the world around us in a spirit of tolerance, open-mindedness, and perpetual questioning. This book is difficult in parts and assumes a great deal of prior experience with logic as a philosophical discipline as well as with the philosophy of science. It is, however, well worth the challenge even for those who are new to these subjects.
