Perhaps the most important work of philosophy written in the twentieth century, Tractatus Logico-Philosophicus was the only philosophical work that Ludwig Wittgenstein published during his lifetime. Written in short, carefully numbered paragraphs of extreme brilliance, it captured the imagination of a generation of philosophers. For Wittgenstein, logic was something we use ...more

Donald Trump's latest protestations about having to fight the "crooked media" remind me of a famous passage from §5.62 of the Tractatus:
Was der Solipsismus nämlich m e i n t, ist ganz richtig, nur lässt es sich nicht s a g e n, sondern es zeigt sich. Dass die Welt m e i n e Welt ist, das zeigt sich darin, dass die Grenzen d e r Sprache (der Sprache, die allein ich verstehe) die Grenzen m e i n e r Welt bedeuten.

In fact what solipsism means, is quite correct, only it cannot be said, but it shows

Wittgenstein was deathly afraid of uttering nonsense; whereas I, clearly, am not—how else could I stomach writing so many book reviews?

This book is a work of high art—beautiful, austere, and sweeping. Wittgenstein is self-consciously attempting to speak the unspeakable—in his opinion, at least—which is why the language is so succinct and severe. He has no use for literary niceties, flowing prose, or extended exposition. One gets the feeling that, for Wittgenstein, writing philosophy is repugnan
What can I say about Tractatus that hasn't been said a million times before? Crystalline... gnomic... dense... wrong. Well, I don't disagree with any of that, but it would be nice to have an image. I ask my subconscious if it can come up with anything, and while I'm in the shower it shows me the sequence from Terry Gilliam's 1988 movie The Adventures of Baron Munchausen, where John Neville and Eric Idle build a hot air balloon made entirely from women's lingerie.

Like many young American readers, I made the mistake of reading the bulk of this text in an In-N-Out, and now it is difficult for me to think about elementary propositions without thinking about someone ordering a cheeseburger, and, subsequently, thinking about the relationship between the sign of "cheeseburger" and the atomic fact of the cheeseburger it refers to. Wittgenstein orders his cheeseburger with the totality of everything that is the case. And he eats the whole thing in under 100 page ...more

I was just going to write, “Of what we cannot speak we must remain silent,” as my review. The book ends with this rather affected proposition, which actually would make a perfect book review for me as well. However, it’s an abomination to read (or pretend to have done so) a book of this stature (supposedly the most important philosophical book of the 20th century, no less) and not write a paragraph or two about it.

The ingenious work which, had it been true, would have provided a firm foundation for Positivism and provided justification for Philosophy's existence. It also would have pretty much been the last word on the nature of and philosophical limits of language. Instead Wittgenstein repudiated this view and put a nail in the coffin with P.I.

Elegant, minimal, logically crystalline. And mostly wrong.

"Για τα πράγματα που δεν μπορείς να μιλήσεις, πρέπει να σωπαίνεις."

Όπως ο ίδιος ο Wittgenstein προλογεί στο έργο του, αν δεν έχετε σκεφτεί από μόνοι σας αυτό που θέλει να πει το βιβλίο, τότε το βιβλίο αυτό δεν είναι για εσάς. Για αυτό ψάξτε πρώτα στο YouTube ή γενικά στο Διαδίκτυο για τον συγγραφέα και την φιλοσοφία του πριν αγοράσετε το βιβλίο.

Πρόκειται με διαφορά για το δυσκολότερο βιβλίο που έχω συναντήσει. Όχι, δεν είναι κακογραμμένο. Είναι όμως το πιο μαθηματικά γραμμένο βιβλίο που διάβασα

What the hell am I supposed to say about this?

The parts I understood were hugely inspirational to my own thoughts, if I did indeed understand those parts, which I suspect I did not.

What a shame that someone so clever who had decided that this book was the be-all and end-all to problems in philosophy could only communicate them in a form that often eludes human comprehension.

It's like the saying that if the human brain were simple enough for us to understand it then we would be too stupid to do s

کانت و ویتگنشتاین

تحقیقات ویتگنشتاین، همچون نظریات بسیاری از فلاسفه بعد از کانت، به نوعی راجع است به معرفت شناسی کانت. کانت با مشخص کردن مرزهای معرفت انسانی، نشان داد که بسیاری از امور به صورت بنیادین قابلیت ادراک توسط دستگاه ادراکی آدمی را ندارند، در نتیجه همیشه در آن سوی مرزها و در حیطه امور رازآمیز باقی خواهند ماند. ویتگنشتاین در ادامه همین سنت، با ریزبینی در دستگاه ادراکی آدمی، یعنی منطق، سعی کرد ساز و کار آن را مشخص کند و مرزهای آن را با دقت بیشتری معین کند. به همین جهت از نمود بیرونی منطق،

I really enjoyed this book, my first by Wittgenstein, a book about the essential function of language and a sort of "theory of everything" of meaning. It starts off as a very cool, clear-eyed, incisive look at what language is, what it does, and how we can cull it to its essence to say something meaningful and true, then ends on an oddly metaphysical note that seems to throw everything that preceded it to the wind.

The format is as economical and mathematical as Wittgenstein's arguments. It is a

Patience is necessary if you're not within philosophy academia, like myself. It's not light reading but, conversely, Wittgenstein is not heavy material. In fact, it's the strict, disciplined simplicity of his ideas that adds some difficulty. The book ends on a fantastic note, either an affirmation or a haymaker to the field of philosophy. I'm still unsure which.

Wittgenstein's Tractatus Logico-Philosophicus is, alongside Heidegger's Being and Time and Wittgenstein's own posthumous Philosophical Investigation, one of the most important works of 20th Century philosophy. It is also one of the very few - the only? - "Great Books" or "Classics" in the analytical tradition. I would further maintain - and have always maintained - that it is among the most beautiful books ever written.

Wittgenstein says explicitly in the introduction of the book that no one has not already had these thoughts will be able to understand it, and should therefore not read it. No doubt this had a great affect on the size of The Tractatus' readership.

I love this book, and I am not sure why. I actually pick it up time-to-time and it is really a book that can't be defined by words - I think about it and it's almost abstract. And that is the essence of the book. How do you define something abstract into words - and are words enough to describe something that can't be said, but can be felt?

First of all, it should be acknowledged that my entire philosophical background is in continental, rather than analytic, thought. I come to Wittgenstein with very little context. The only other philosophers Wittgenstein directly references in the Tractatus are Frege and Russell, neither of whom I have studied. My only preparation for reading this was a (very good) book by Anthony Rudd that compared Wittgenstein's work with that of Heidegger, finding unexpected similarities in their projects. Bot ...more

If I may use a crude simile for illustration, Wittgenstein says that knowledge, or language, or science, is like a pile of cordwood. Each piece of wood is a proposition that mirrors or pictures a fact in the world. The pieces of wood are stacked on top of each other according to the logical rules for concatenating propositions, including implication (for causation) and universal quantifiers (for scientific principles). The pile of wood rests on a bottom layer of “elementary propositions,” of whi ...more

But I do admit that I have not read too many philosophical essays yet, so this book might not have been ready for me yet (yeah, Wittisteini, how do you like the logical form of THAT sentence? =D )

I actually like the form, it lays bare how every argument fits together so that this somewhat dense work is fairly straightforward to follow. It lines up nicely with his metaphor for how logical systems and frameworks act as a grid laid atop everything that is, so there is a real nice uniformity to this work. The only inaccessible aspects are the notation (he explains the notation after using it, but there are glossaries out there if you are stuck) and Wittgenstein's annoying habit of vaguely re ...more
