So, basically, what you're saying is that the writing is mediocre, and it's about as clear as mud. You may be right, and it's especially true if I'm trying to explain this material to people with no background in this area of philosophy. I don't mind the honesty. Let me give the next few paragraphs to see if it helps, with the caveat that none of this is written in stone, obviously.

Before we get to the subject of epistemology, we will need some background on how meaning has been traditionally thought of in philosophy. Traditionally, the meaning of a word was thought to be connected with the object it refers to, that is, its referent, or the object it denotes (the object the word points to). The idea that meaning is directly connected to things or objects in reality can be traced back to Augustine (354 A.D. – 430 A.D.). Thinking of meaning in this context culminates in the twentieth century with Ludwig Wittgenstein’s
Tractatus-Logico Philosophicus (originally published in German, in 1921, then translated and published into English, in 1922).
Again, just as our treatment of epistemology is just meant to be an overview, so is our look at Wittgenstein’s ideas only meant to be a glimpse at some of his ideas. This glimpse is mainly focused on his ideas about meaning; and to briefly contrast his ideas of meaning in terms of his early and later philosophy.
Wittgenstein (1889-1951) was born in Vienna, Austria, and he was the youngest of eight children. He came from a very cultured and very rich industrialist family, where the arts, especially music, played a central role. In fact, Johannes Brahms, who was considered a close friend, would come to the Wittgenstein home and play his music; and Brahms was also known to have given some family members piano lessons.
Ludwig was educated at home until the age of 14, when his parents decided to send the young Wittgenstein to Linz to prepare him in mathematics and the physical sciences. It seems that the young Wittgenstein wanted to study with the physicist Boltzmann, however Boltzmann died in 1906. After being educated in Linz for three years, he then went to Berlin to study mechanical engineering at the Technische Hochscule at Charlottenburg. After two years in Berlin, he went to England where he became a research student of engineering at the University of Manchester. During this time, he engaged in aeronautical research, and went from experimenting with kites, to the construction of a jet reaction propeller for aircraft. The design of the propeller was a mathematical endeavor, which eventually led the young Wittgenstein into pure mathematics, and then, to the foundation of mathematics.
Apparently, his interest in the foundation of mathematics led him to Russell and Whitehead's work, called,
The Principles of Mathematics.
The Principles of Mathematics greatly affected the young Wittgenstein, and this interest led him to the works of Frege, who was the founder of modern mathematical logic. So, it was through Russell, Whitehead, and Frege's works that Wittgenstein entered into the study of philosophy.
Wittgenstein’s early work, the
Tractatus, is a more traditional philosophical work. It is traditional in the sense of the kind of analysis he is doing. He digs into a proposition as if to find some essence that will logically connect it to the world. It is an a priori analysis of the proposition that shows how propositions picture (or mirror) the world of facts through a one-to-one correspondence between the proposition, and the fact it pictures (it is a picture theory of language). It is through this investigation that Wittgenstein hopes to find an exactness of meaning, or an exactness of expression. He accomplishes this by breaking down the proposition into what he believes are its essential parts, namely, elementary propositions, and even smaller parts, called names. So, according to Wittgenstein, “…propositions must bring us to elementary propositions, which consist of names in immediate combination (T. 4.221).” Names, again, being the smallest constituent part of the proposition. And, since Wittgenstein held to the traditional view of language, namely, that the meaning of a word is the object it refers to, or the object it denotes (T. 3.203). He then links the proposition, via a name, with an object, the smallest constituent part of a fact. Facts being broken down into atomic facts, then into objects. There is a direct connection from the name (the smallest component of the proposition) to the object it represents (the smallest component of the fact). In this way we have a direct link between the proposition and the world of facts. This brings us back to the traditional view of meaning, that the meaning of a word is its referent.
Wittgenstein’s analysis is much more complicated than what is presented here. My only point is to show how meaning was thought of in the traditional sense, and how Wittgenstein’s
Tractatus continued this historical line of thinking in a much more exacting way. This is probably why Russell mistakenly thought Wittgenstein was trying to construct an ideal language. Because if Wittgenstein was correct in the way he thought of propositions, then you would have more precision based on the nature of the proposition, and how it pictured the world of facts.
Wittgenstein’s later work, in some ways, is continuous, namely, he continues to think of many of the problems of philosophy as misunderstandings of the logic of our language. It would be a mistake to think that his later philosophy completely repudiates his early philosophy. He mainly repudiates his method of analysis. This contrast of methods into the nature of the proposition, is what separates his early philosophy from his later philosophy. If there is a gap between the two periods of his thinking, it is a gap of method. One could say that the difference between these two investigations, is like comparing the a priori (independent of experience) with the a posteriori (dependent on experience).
Wittgenstein’s early philosophy starts when he meets both Bertrand Russell (1911), and Gottlob Frege (1912); and his later philosophy starts roughly around 1929. His later philosophy is most famously expounded in the
Philosophical Investigations; and culminates in his final notes on the subject of what it means to know, called
On Certainty. His final entry occurs two days before his death in April 1951.
It is important to understand the background of Wittgenstein's works in order to better understand his thinking. I am not going to be able to give those of you who are interested a complete background of what was going on in philosophy at the time, vis-a-vis Bertrand Russell, A. N. Whitehead, and Gottlob Frege. I will only give you bits and pieces in order to show the connection with Wittgenstein’s analysis of what it means to know, and the view of epistemology as presented in these musings.
