Wittgenstein's philosophical thoughts, while at first has been influenced by the positivist and empirical thoughts of Frege and Russell, he can’t deny his roots of mysticism. I would consider him as the last of the line of the great German transcendental idealism, with his works set as the finale and completion of the thought. It was his ideas alongside with Kant and Schopenhauer that formed the bulk of my thoughts to satisfy my rational side of thinking. From Kant, I derived my thoughts that sensibility and understanding formed the self-limiting limit of our knowledge. From Schopenhauer, I divined that the body as I know is appearances constrained by time and space, but I can conceive of myself free from the physical world. Freed from time and space, this I is surely not a phenomena, but a noumena (the things that exists prior to our perception). And because this I exists prior to my perception, even of my own body, surely even the basic movements of the body flowed from this noumenal side of “I”. This is what is called as will, the upsurge of this very will from the noumenal world manifested in the phenomenal world, clothed in the defining fabric of time and space. And lastly from Wittgenstein, I affirmed that because this noumena which is “I” can never be known except in the phenomenal world, I lack the very basic faculty to expand on its nature, other than duly acknowledging its existence. What can be said, therefore, can be said clearly, and whereof one cannot speak therof one must be silent. This trinity of thoughts form the fabrics of reality, now I stand at the edge of precipice, the end of the line, biding my time to perform the leap of faith.
Now, I'm going to embark on a long digression regarding the spirit of Wittgenstein when he wrote the Tractatus and a cursory remarks regarding his later philosophy. Tractatus' main idea is hidden behind his words of: "...There is indeed the inexpressible. This shows itself; it is the mystical..."
Thus Wittgenstein are trying to express the inexpressible i.e. things that can only be shown, not said such as ethics, religion, meaning of life. He insisted that the realm of the ethical is delimited (or can only be) through his book. If Kant said I had to forgo knowledge in order to make room for faith, Wittgenstein said that in order to make room for faith, I had to define knowledge’s limits.
He agreed that if only you do not try to utter what is unutterable then nothing gets lost. But the unutterable will be-unutterably-contained in what has been uttered!
How then Wittgenstein aimed to express the inexpressible? Was he not contradicting himself by putting his philosophical thoughts in words? This jettison can be bypassed if one knew that Wittgenstein once said that philosophy ought only to be written in poetic composition. In poems, nothing directly given to its deeper meanings, but somehow it can convey the inexpressible meanings of life.
Now we can understand that the whole picture of the Tractatus is to define the expressible world. And this expressible world includes a several stages that resemble a flow, a process. We have the world, the data procured by the world, the thoughts formed from the data and then the depiction of the data in the form of proposition.
The world according to Wittgenstein is everything that is the case. What this means is that the world is everything that is so, as understood and limited by both sensibility and understanding. This simple definition of the data is in parallel with Wittgenstein’s rejection of the use of concepts such as objects, relations or predicates in defining the world. Thus, a stricter definition of the world could be that everything that is the case (it is so) as limited by the infallible sensibility.
The world then is obviously not static nor does it standalone. The world consists of data which contains, Wittgenstein said, “a state of affairs”. This data of the world in a state of affairs, is what Wittgenstein called as a fact. “He is in the room” is a fact simply describing the perceived sensible data that a man is in the room, being in the room is the state of affairs.
This facts then, rightly contains parts and relations to the other facts in the world. The world now stands in a web of relations. Because facts contain parts, it then can be pictured corresponding to the objects that constitute the facts. The author used the incident where Wittgenstein read about the court in Paris who uses a model to reconstruct an accident. The model stands as a picture to the fact (an accident has occurred) and the parts of the fact (the houses, the cars, the people) that represents the robustness of the initial fact constitute the logical form of the picture. This logical form of the picture is what we called as thought. In other words, thought is the representation of the fact via a logical picture.
And thought is, in return, when expressed in a way that is perceptible to the sense is what we called as the proposition. A complete cycle of the stage reveals that Wittgenstein wished nothing except the perfect recreation of the mental processes in both perceiving and articulating about the world. A constant reminder should be held in mind, whenever we faced difficulties in reading Wittgenstein, is that he never wished to construct an abstract and overly complicated notion of the world. He simply wished to have a perfect picture of reality.
So a proposition is a thought which is a picture reconstructing the state of affairs of the fact in the external world. If the proposition reflects the actual state of affairs it is true, and false in the opposite.
The important consequence from this is that propositions are supposed to reflect a portion of reality, and everything beyond that is senseless. Logic studies the inferential relation between one propositions to another, such as “Socrates is mortal” correlates with “Socrates is a man” and “All man are mortal”. But the entire three propositions are basically analytical statements that only serve to delineate whatever that is has already been contained in the first proposition. Logic thus is a tautology. Tautologies such as “It is either raining or not” sounds logical but it does not reflect a portion of reality, thus senseless. The proposition “it is either raining or not” does not resemble with any picture at all, thus it is again senseless. It is hard to grasp in the first place because we are embroiled with the fact that the statement is logical and thus true. But the statement only gives us information about our language, not a picture of reality. It is this automatic confusion between robustness of language and the depiction of reality that drives all the catastrophes in philosophy. Thus even though it is perfectly logical, it is simultaneously “transcendental” because it can only be shown (or felt) but cannot be said (in reality). Therefore, all propositions in the realm of the transcendental, according to Wittgenstein, can only be shown but not said. “The reason for this is that meaningful propositions are limited to picturing states of affairs in the world, and values found in ethics and aesthetics cannot be found in the world.” This is the essence and limit of the human world, as understood by Wittgenstein.
Thus it is clear that philosophy is not about debating transcendental propositions that is totally using language for an entirely wrong reason, but it is about elucidations of the limited the use of language and propositions to represents only possible state of affairs in the world and to correct any confusion while using it.
The later Wittgenstein was thought to be a complete break from the previous conclusions he made in the Tractatus. In my opinion, I maintained that he retain the very same conclusion albeit with a different kind of attitude. His later works still focused on the correct use of language but not in a scientific way as he famously did in the Tractatus, but in a more open discussion, resembling a sage speaking to his students. Therefore, I have no problem in reconciling his early and later thoughts.
