Described by the philosopher A.J. Ayer as a work of 'great originality and power', this book revolutionized contemporary thinking on science and knowledge. Ideas such as the now legendary doctrine of 'falsificationism' electrified the scientific community, influencing even working scientists, as well as post-war philosophy. This astonishing work ranks alongside The Open Society and Its Enemies as one of Popper's most enduring books and contains insights and arguments that demand to be read to this day.

`One of the most important documents of the twentieth century.' - Sir Peter Medawar, New Scientist

`One cannot help feeling that, if it had been translated as soon as it had been originally published, philosophy in this country might have been saved some detours. Professor Popper's thesis has that quality of greatness that, once seen, it appears simple and almost obvious' - Times Literary Supplement

Reviewed in the United States on October 4, 2017
The Logic of Scientific Discovery is a deserved classic. Rarely has the genius of one man been able to so transform the tradition of scientific interpretation as Popper did. But since Popper has so many contemporary advocates I thought in this review I could suggest some problems or misinterpretations in his thought. Others have already explained his contributions with enthusiasm.

First, Popper is often seen as advocating a skeptical way of life--the principle of falsification is made to mean that one should always try to falsify one's one own theories and worldview. There may be some support for this philosophy in the Open Society but not in the Logic of Scientific Discovery. Here, Popper is explicit that he is not proffering a philosophy of life but a methodology for science.

Another related misconception is that Popper does not contend that his logic is the way science has historically progressed. The Logic of Scientific Discovery is explicit that it is normative. It argues not how science has progressed but how it should progress. The fact that Popper was so personally authoritarian that the line among his students was that his other major work should have been called "The Open Society by One of Its Enemies" seems eerily consistent with a philosophy professor dictating to scientists how they should conduct their work.

And here is where I find the work someone dated. Popper argues against the inductivism epitomized by John Maynard Keynes but seems oblivious to the work of statisticians like Ronald Fisher. Fisher, with his method of randomized experimentation was able to show the validity of inductive causal inferences. In the 1970s statisticians like Rubin extended these inductive arguments to observational studies. Meta-analyses using Bayesian inference have also shown then value of induction. Obviously, Popper cannot be held responsible for not recognizing the Rubin causal model. His inattention to Fisher, however, is troubling since he was a contemporary.

Most social science continues to progress within the Fisher/Neyman framework along with Bayesian advances. To be honest, Popper's work in this domain can seem as passé as the inductivism of Keynes.

That the Logic is a work of genius is indubitable. I would argue, however, that falsification is not the one valid method for science. A fortiori it is not a philosophy of life all human beings must follow.

Popper, a member of the elite group, "the Vienna circle," descents from Logical Positivism also known as Logical Empiricism, when he asserts that "the verification Principle," of which, all positivism rests, collapses if it can't sustain the scrutiny of falsification. The obvious contradiction emerges when one ask, "How does one verify the verification principle?" This is a clear example of "begging the question." Karl Popper knew this. Logical Positivism is entrenched in the sciences of modern America. "The Logic of Scientific Discovery" is a fascinating read and over turns the junk science of post modernism which often passes for science. Even empirical physics was abandoned over a 100 years ago. Popper requires scientists do the hard work that is required to reach a valid conclusion. This is a wonderful work for anyone interested in truth, everyone else, don't waste your time.

Even if viewpoint is perhaps dated, this classic has lasting value, still reads well, and is generally accessible. Popper himself would not appreciate a five-star rating on principle - nor complete agreement of all readers with all contents... and if your reach doesn't occasionally exceed your grasp, what does that say? But I generally found his viewpoints stimulating, valuable, and practical... glad to have read it, though the basic points are more easily available in public domain.

We are in 1934, Popper is remembering us that when a scientist finishes writing down a theory the community starts a race to falsify the theory so to find progress. In a sort of recursion, Popper starts with the hypothesis that a good theory is therefore a theory that can be falsified. This subtle focus on falsification allows us to demarc what is in the realms of science and what is superstition (works in hindsight). Brillant. Guess what he does as soon he finishes writing down his theory? Yes, he goes about trying to falsify it comparing with conflicting theories. He is deeply influenced by quantum mechanics engaging in long discussions around probability and logic to construct adventurous theories (his own definition). Takeaway: was pleasing to see a philosopher using precise terms and simple language.

The formatting on the kindle edition of this book is terrible! I don't understand why publishers get so lazy about the appearance of their E Books. Considering that I spent $13 on it, I expect it to look good!

Don't get me wrong, it's readable, but there's no indents on the paragraphs and there's huge spaces between what I guess are paragraphs? Too me this looks unprofessional and lazy. I've seen better formatted books in the free section of Amazon. I gave the book five stars only because Amazon doesn't separate the reviews of the E Books from the hard copies and the book itself is a classic.

I honestly wanted my money back but there's no way to do that that I know of.

I recommend you download a sample of this book to your kindle first before you buy it. You may not feel as annoyed by it as I do. Personally, I'll be checking the samples of every E Book I buy from this point on since this was a huge waste of money in my eyes.

I bought "Used - Good" and whoever decides what counts as good there must not care much. It had liquid stains, dings and dents, and was underlined quite a bit. It should have been labeled "Used - Acceptable"

This is an absolute classic, a masterpiece of clear thinking around the nature of scientific proof. The only problem I had with this edition was some really annoying typography - "ff" came out as "fl" every time, for instance, and sometimes there were spaces missing between words - "thesubtletiesofargument". Chapters would start at the bottom of pages. It is great to have classics such as this redone for Kindle, but I would have expected the publisher to spend a little time on copy-editing before the launch.

5.0 out of 5 stars Falsifiability as a demarcation criterion
Reviewed in Canada on May 23, 2019
Many important scholars have discussed and are still discussing the demarcation issue. What distinguishes science from non-science. Popper’s criterion has two distinct advantages. First, it is a priori. It does not wait for the project to unravel but informs you in advance on its scientific substance. Second, it has an appeal to non-philosophical common sense. If a theory cannot be subjected to credible testing, it is not scientific. This simple statement is one that everyone can understand.

There is no way to know a priori whether Popper’s falsifiability is an inherent property of the theory or a property of human capabilities. A theory can be unfalsifiable within the current state of knowledge, technology and experimental capabilities but can become falsifiable, thus scientific, with technological progress years or centuries later. We can have therefore a “conditional falsifiability” upon the condition that a gap in our knowledge will be filled at some point in the future. In our testing of the theory we should err on the safe side, that is the side that favors the theory and views falsifiability as a property of human capabilities.

This is not just stimulating reading, it is a "must read" for anyone engaged in scientific work.

1.0 out of 5 stars Kindle-version full of typos and mistakes
Reviewed in Italy on August 14, 2019
I am really disappointed: the book itself is great (Popper was a genius and wrote very clearly), but this kindle-edition is full of typos and mistakes which render it almost incomprehensible in its most technical (math and statistics) parts. I strongly advise against the purchase of this e-book: buy it in the paper form! Who was in charge of preparing the kindle-edition did and awfully sloppy and poor job! The worst money spent on an e-book ever!
