Bedrock Beliefs and Their Epistemic Importance
(My Philosophic View of Wittgenstein’s On Certainty)
Biographical Sketch:
Ludwig Wittgenstein was born in Vienna, Austria in 1889. He was the youngest of eight children, five boys and three girls. His father, Karl Wittgenstein, was a remarkable man who became a leading industrialist in the iron and steel industry; consequently, the Wittgensteins were very wealthy. In addition, Ludwig’s mother, Leopoldine, had exceptional musical talents and passed her love of music to the children. As a result, all the Wittgenstein children were exceptionally gifted with artistic talent and superior intelligence.
At a young age, Ludwig demonstrated an interest in machinery, which led to his interest in engineering. He was educated at home until the age of 14, then was sent to Linz in northern Austria to further his studies. After his education in Linz, Wittgenstein went to Berlin to study engineering (1906-1908). In 1908 Ludwig enrolled at the University of Manchester in England to study aeronautics. His research eventually led to the design of a jet reaction propeller, which was a mathematical endeavor. The mathematics of his research eventually led him to the philosophy of mathematics. Specifically to the Principles of Mathematics, published in 1903 and written by Bertrand Russell (not to be confused with the Principia Mathematica, published in 1910 and written by Russell and Whitehead). The main goal of thePrinciples of Mathematics was to establish that the propositions of mathematics rest on a few logical principles. Another mathematician from Germany named Gottlob Frege was also working on the same idea. Wittgenstein eventually meets with Frege to discuss some of his thoughts, and consequently, Frege recommends that he go to Cambridge to meet Russell. Russell sees talent in Wittgenstein, which encourages Wittgenstein to pursue philosophy.
If you want a more in-depth biography of Wittgenstein, there are plenty of books to read (e.g., Ludwig Wittgenstein by Ray Monk and Ludwig Wittgenstein by Norman Malcolm).
I will set out an epistemological theory that enunciates a particular set of propositions derived from Wittgenstein’s final notes called On Certainty, published in 1969. These bedrock beliefs (often called hinge propositions) were identified mainly by Wittgenstein in the final years of his life (1949-1951). I am not claiming anything original in my thesis except to point out that bedrock beliefs have an essential epistemological role that advances the subject of epistemology in ways that few philosophers, if any, before the writing of On Certainty, have considered. I am also not claiming that my thoughts necessarily agree with Wittgenstein’s, nor am I claiming that they disagree. Nevertheless, my thinking on this subject would not have gone in the direction it did without Wittgenstein’s keen intellect expressed in the Philosophical Investigations and in his final notes called On Certainty (hereafter referred to as OC).
Wittgenstein begins OC as a response to G.E. Moore’s papers, A Defense of Common Sense (1925) and Proof of an External World (1939), in which Moore lists several propositions that he claims to know with certainty, such as, “Here is one hand” and “There exists at present a living human body, which is my body.” These propositions supposedly provide Moore with proof of the external world, and as such, they seem to form a buttress against the arguments of the radical skeptic, which is why Moore is making the argument.
Moore says, “I can prove now, for instance, that two human hands exist. How? By holding up my two hands, and saying, as I make a certain gesture with the right hand, ‘Here is one hand’, and adding, as I make a certain gesture with the left, ‘and here is another’. And if, by doing this, I have proved ipso facto the existence of external things, you will all see that I can also do it now in numbers of other ways: there is no need to multiply examples. But did I prove just now that two human hands were then in existence? I do want to insist that I did; that the proof which I gave was a perfectly rigorous one; and that it is perhaps impossible to give a better or more rigorous proof of anything whatever. …(G.E. Moore, Proof of an External World, 1939).”
It is undoubtedly the case that OC goes beyond Moore’s propositions, so it is not just about Moore; it is about knowing, doubting, making mistakes, reality, empirical statements, certainty, acting out beliefs, rule-following, etc., so it covers a range of topics about what we know, and how it fits into our language. It is important to note that not everything in OC should be seen as a response to Moore. However, Moore provides the impetus for Wittgenstein’s final notes and is mentioned throughout OC.
Wittgenstein criticizes Moore’s use of the word know and the skeptic’s use of the word doubt, and he emphasizes the relationship between the use of these words as an essential part of the language-games of everyday epistemology.
Bedrock beliefs provide the grounding for our language-games, which is analogous to how the rules, the board, and the pieces in chess function as the grounding (reality background) for the game of chess. In fact, without these beliefs it is hard to imagine how language would get off the ground. It would be like trying to imagine a game of chess without the rules, the board, and the pieces. For example, there would be no such thing as a bishop move without the rules, the board, and the pieces. Such a move would be nonsense. The same is true of our concepts, namely, knowing, doubting, making mistakes, rule-following, etc.; these would all be nonsense without the grounding of certain primitive or bedrock beliefs. Such beliefs are at the heart of a correct understanding of knowledge, directly affecting phrases like “I know that such and such is the case” and “I doubt that such and such is the case.”
Although Wittgenstein criticizes Moore’s propositions, he is not entirely unsympathetic to Moore’s argument, which would look something like the following:
1) Moore knows that he has two hands.
2) Moore makes the inference from the fact that he has two hands to conclude that an external world exists.
3) Hence, Moore knows that an external world exists.
