Pragmatism: its Conception of Unverified Truth #2

Essay by an anonymous contributor* reposted from Pi Alpha

 
In this, the second of two posts, Pi presents reflections on ‘Pragmatism’s Conception of Truth’, a title which William James chose in 1907 for a classic paper on pragmatism.
In last month’s post, we considered pragmatism’s conception of verified truth. However, many of our beliefs are either not verified, or are only partially so. Rather, the vast majority of the beliefs we live by are unverified.

William James uses the example of a clock:  we do not know how it works, nor have we seen the insides of it. ‘We let our notion pass for true, without an attempt to verify.’ We believe the clock to be keeping accurate track of time with its cogs and weights, but we do not really understand how.

This is not a problem for pragmatism, as James points out: ‘Just as we here assume Japan to exist without ever having been there, because it works to do so.’ So because of this, we assume that the thing hanging on the wall with the hands and a face is a clock which keeps accurate track of the passage of time, because it works for us to use it in such a way.

The verification of the assumption here means that our incorporation of this assumption does not contradict previously held beliefs, or is so overwhelmingly powerful that previous truths are altered (as little as possible) to make room for this new truth. The fact that we could verify that the cogs and weights actually do keep an accurate track of the passage of time counts in this case as verifiability. It is because we know previous truths about cogs and weights that we can believe that a series of them can count units of time. This information is useful to us in our new belief that the thing on the wall is a clock and functions as such. ‘We use it as a clock.’ That is what makes it useful to use in a situation where knowing the current time is helpful to us. In another situation, knowing the time may not be helpful to us. In this case it does not matter if the cogs and weights actually do keep an accurate track of time.

Another reason that James gives for us counting the possibility of verification as being just as good as actual verification is that ‘all things exist in kinds (groups) not singly’. When we verify a certain belief that we have, that verification can then be used to verify other beliefs of the same kind, or of the same type. ‘A mind that habitually discerns the kind of thing before it, and acts by the law of the kind immediately without pausing to verify, will be a “true” mind in 99% of cases, proved so by its conduct fitting everything it meets, and getting no refutation.’ These semi-verified or non-verified truths give us the same advantages of full verification, such as saving effort as we verify all our beliefs, which thus leads us to say that these beliefs are true.

Our actions (formed through beliefs), which allow us to willfully lead ourselves through persisting reality, form into habits of action. These habits of action are carried out at an almost unconscious level as most of our un-verified (but verify-able) beliefs form actions that we carry out every day.

Consider habits, as an example. Habits are things which we do every day, but do not really think about, like going to work or playing a certain card game. As long as these habits contain beliefs that are consistent with this persisting reality or realities, and lead us to moments worthwhile, they will be followed.
‘To “agree” in the widest sense with a reality, can only mean to be guided either straight up to it or into its surroundings, or to be put into such working touch with it as to handle either it or something connected with it better than if we disagreed.’ 
 Reality is not a set thing that our ideas either match up with (which is true ideas) or do not (which is false ideas), but it is made by us. In pragmatism, to copy a reality is one way of agreeing with it, but not essential. The essential part of agreement is how you use it to guide you through this persisting reality we seem to be experiencing. Names are just as true or false as our other ideas or what James calls definite mental pictures. Names are arbitrary, however once set they need to remain so or there would be confusion. Names are labels given to objects that have the same grouping or kind, and as long as we use the right name for the right object, our name is always true.
‘You are sure to get truth if you can but name the kind rightly, for your mental relations hold good of everything of that kind without exception.’
In the end, philosophy needs to give us a theory that will affect out lives, giving us something almost tangible that we can hold on to and use. Pragmatism is not strictly speaking a philosophical theory of itself, but more of a lens through which all other theories must pass. It grants an idea to be true, and then asks, so what? What definite difference will this idea make to me in my life, if I were to believe it or chose not to believe it. It must always be remembered that all previous truths must be affected as little as possible when incorporating new beliefs.
‘We must find a theory that will work, and that means something extremely difficult, for our theory must mediate between all previous truths and certain new experiences.’ 
 In science, there are often two or more competing theories which attempt to explain the same phenomenon or situation. In times like this, we should look as much as possible to the explanation that incorporates all previously held truths, while at the same time accurately predicting new experience. This is a rather easy thing to do. We are naturally disposed to incorporate the theory which conform to our preconceived notions, and thus reject the one which changes our previous truths more.

Truth has a certain ‘cash-value’ in pragmatism. Truths pay. They pay because they lead us towards some way of predicting our next experiences. The truths that pay more, help us more, by leading us towards worthwhile moments in our experience. Pragmatism is a name for a verification process of our ideas and beliefs: truth is largely made up of other truths. It is a lens through which all other theories must pass, in order for us to incorporate them into our belief system.

Experience has a way of ‘boiling over’, which is to say that it forces us to correct our beliefs due to new experiences happening, which do not conform to what we believed before. While the facts may change in our situations, our use of truth also does.
‘The “facts” themselves meanwhile are not true. They simply are. Truth is the function of the beliefs that start and terminate among them.’
 Beliefs make us act, and as they do so so, they bring with them new experiences which themselves redefine the belief’s guiding our actions. This may be likened to Berkeley’s descriptions of matter: people thought he was denying its existence. Similarly, pragmatism was accused of denying truth, but clearly just redefined the word to mean something other than copying a stagnant reality.

Copying reality is really not important. Who cares if our beliefs copy reality, if what we really want is to be able to use our beliefs to guide us to where we want to be? And to do so through this persisting reality that we seem to be experiencing through our sensory perceptions.

Pragmatism: its Conception of Verified Truth #1

Essay by an anonymous contributor* reposted from Pi Alpha

In this, the first of two posts, Pi presents reflections on ‘Pragmatism’s Conception of Truth’, a title which William James chose in 1907 for a classic paper on pragmatism.
One of the most basic questions a philosopher can ask is: ‘What is truth?’ What does it mean for a thing to be ‘true’?

Truth, as a dictionary would tell you, is a property of our ideas. Their agreement (between our ideas and reality) is truth, where their disagreement is falsity. This tells us what the word ‘truth’ means in conversation, but a dictionary cannot tell us what is meant by the term ‘reality’ or the agreement of our ideas with this reality. A true idea, in the non-pragmatic sense, is an idea that accurately reflects reality. People would never believe something that they know to be false, so everyone’s beliefs are about something that they think is true. This does not really get at the heart of the problem, though, which demands what reality?

The great American philosopher (I think, the first great American philosopher) was William James. His development of the school known as pragmatism created for me America’s first original school of thought, and thus America’s first real contribution to the world of philosophy. Indeed, when James headed the Colombia philosophy department, the British philosopher Bertrand Russell, whose interests spanned the logical structure of language, said it was one of the finest schools in the world. James did not like the Cartesian idea that truth is the correct reflection of reality, but instead insisted that truth is made by us through interactions with reality, although not one stagnant reality.

Previously in Europe, the pervasive school of thought was that if your idea could be said to be true, then ‘you are where you ought to be mentally’. However, pragmatism asserts that you should take a belief to be true, then ask:
‘What concrete differences will its (an idea’s) being true make in anyone’s actual life?’ 
This question becomes the foundation of pragmatism: what experiences with reality would be different if the belief were to be true or false? James then goes on to make his largest claim, that truth ideas are those that:
‘we can assimilate, validate, corroborate and verify’
This is the practical difference that true or false ideas have to us. Indeed, this process of assimilation, validation, corroboration, and verification allow us in effect to make an idea true or false. ‘Truth happens to an idea.’ This thought is in direct response to the European schools of thought that had a stagnant reality which true ideas correspond to and false ideas do not. In effect, James is claiming that ideas become true or are made true by actual events.

The possession of a true idea is not an end in of itself, but can be seen as a tool that allows us to function towards our desires and goals. James brings up an example that I shall use for the rest of this and the next post: imagine that you are lost in the woods and starved, but you come to what appears to be a track leading in some unknown direction. If you know that it is a cow track, and that cow tracks lead to farmers’ houses, then this information is useful to you. ‘The true thought (the one that the track is in fact a cow track) is useful here because the house (at the end of the track) which is its object is useful.’ In this scenario, the track is useful because of the situation you are in, which is being in need of food. But if the situation were slightly different, the usefulness of this truth is changed as well.

Let us say that the track that we come to appears to us to be made by a goat and not by a cow , along with the knowledge that cow tracks lead to farmers’ houses and goat tracks lead to large fields. This then changes the usefulness of the path, but does not change the fact that the information that we already knew is useful to us. Back to the cow tracks scenario, let us say that it is a cow path, not a goat one. The information that goat paths lead nowhere useful is in itself useful, although not right now. James calls these extra truths.

At this point I feel I need to stop and re-clarify the example. The reason we know that goat tracks lead nowhere is because before, in a different woods, we followed a goat track and it led us nowhere, whereas previously the cow tracks did lead to a safe house. This process is the verification process, that tells us what ideas we have are true and which ones are not. However, if say we had forgotten this previous adventure, and followed the goat tracks and they led to a house, then the truth that goat tracks do not lead to houses would be false.
‘Whenever such an extra truth becomes practically relevant to one of our emergencies, it passes from cold storage to do work in the world and our belief in it grows active.’ 
 This idea of goat tracks leading nowhere, but cow tracks leading to houses, can be said to be true because it is useful, but also can be useful because it is true. Both these things say the same thing, that ‘here is an idea that gets fulfilled and can be verified. ‘True’ is the name for whatever idea starts the verification process, ‘useful’ the name for its completed function in experience.’ True ideas obtain a certain value based on their usefulness to us in situations. Pragmatism’s general notion of truth is about the way one moment in our experience with reality may lead us towards similar desired moments. We as humans, with a finite unknown amount of time here, want moments that are worthwhile having. True ideas are those that get us to our destination of worthwhile moments.

Experience is filled with regularities. One moment can (and often does) influence the next moment we have. ‘Truth, in these cases, means nothing but eventual verification.’ This verification takes place when we interact with reality from one moment to the next moment (or what I call, existence through persisting reality) and our ideas are being used to influence this persisting reality.

Back to our scenario of the cow tracks: verification takes place when we follow the tracks and actually see the house and get food and rest inside. Or the goat tracks one: the verification process takes place when we get to the end of it, and there is no house to take shelter in or give us food. Verification can be positive or negative. If the cow tracks lead to a house, it is verified positively. If it leads nowhere, it is verified negatively. On the other hand, if the goat tracks actually lead to a house, then it can be said that our previous belief was false, or that its verification was negative. We have verified that our previously held belief was false.
