Truth
Truth is a word we use to compliment texts that are coherent
and well tested against experience.
So first of all, truth is a word. It is something we say
about texts. It does not refer to any object in the world of experience. It
refers to a relationship of agreement. For example, when we say, "That is
true", we often simply mean, "I agree". We mean that the text
agrees with our experience or with other texts that we take to be true.
Since truth is not an object that can be immediately
perceived, a text must somehow be evaluated to see if it is true. It must be
tested. For simple observation statements, we can simply check to see if we
experience what is stated. For example, you say, "It is snowing," and
I look out the window and see that it does indeed appear to be snowing. Then I
am willing to say that your statement is true. It is an honorific I confer on
your statement as a result of my testing.
For more complex texts, more complex testing is needed. For
example, if I say, "This is an accurate map," it will be difficult
for you to immediately make a judgment. You can try to use it and see if you
get lost. As long as it works well, you will tentatively accept my assertion.
On the other hand, if you have had bad experiences with other maps I have given
you, you may have your doubts. In this case, you are not comparing the map
directly to experience but to a whole network of other texts and experiences.
One approach to evaluating texts is to consider all of the
texts that you tentatively accept at any point in time. You use this network of
texts until a problem comes up. One problem may be that you discover an
inconsistency between some of the texts in your network. Past experience has
shown that texts that are coherent with other true texts are more reliable than
those that are inconsistent with them. The world of experience seems to be
largely self-consistent. So when your working set of texts gets out of
coherence, you make moves to restore it to coherence, by changing or ejecting
some of the texts.
The same process is needed when you have a new experience
that contradicts one of your texts. You need to make adjustments. What specific
adjustment you make is fairly open. Which texts need to be altered depends on
many factors. For example, we would tend to try changing the rules of logic or
some well tested, highly useful physical theory only as a last resort. Instead,
we may go back to check our experience again. Maybe we were mistaken. Maybe we
misinterpreted what we experienced. But eventually, if there is no other way,
even these texts may need to be changed.
This process does not result in one true network of texts,
though, since others may decide on different adjustments that could still work.
This makes the truth of the texts tentative and evolving. Some people have
trouble with this rough and tumble approach to truth. They would prefer
something less fluid. But even with this approach, a great deal of the system
is usually preserved. Only rarely is a major rearrangement needed.
Still, is there a more stable approach? Take the two main
threads of coherence and testing against experience. If you emphasize
coherence, perhaps taking mathematics as your model, you can imagine that the
world is one vast system of inter-related patterns. By developing more and more
comprehensive, coherent systems, you can hope to get closer to that universal
pattern. You can further claim that you have direct access to those patterns
though your reason. Then you can get at the truth without all the messy
interactions with the world of experience. The problem though is that the
systems you develop may in fact have no relationship to the world of
experience. They are simply texts, however elegant. And it is very difficult to
show others that you have direct contact with a universal world of patterns
when all they see is words.
Going to the other extreme, you can emphasize testing
against experience, perhaps taking observation statements as your model. You
can then say that truth is a direct correspondence to reality. The first
problem with this is with the term reality. How does reality differ from
experience? You could say that it is the world behind experience, that causes
experience, but that we cannot experience it directly. It must always be
mediated through experience. But then how do you know your experience reflects
it? All that it seems that you can do is test against the experience itself.
Reality seems to be just that in experience which resists your desires, forcing
you to “face reality”. The second problem is that observation statements do not
cover enough territory. Almost immediately you are into theories and maps and
hypotheses and you cannot derive these from observation statements. Instead you
invent them and use observation statements to invalidate them if they are
inconsistent. Finally, the observation statements themselves can be very theory
laden. Why did you choose those particular words and concepts? Couldn't you
have used others?
So it seems we are left with a whole range of texts that
need to work together, some closer to the pure coherence end, some closer to
the direct description of experience end, but a lot in the middle. We can make
these texts more useful by keeping them as coherent as possible and by testing
them against experience as best we can, and we can use the word truth to praise
them. This may be a weaker use of the word than some of us had hoped for, but
it is still a useful word and in the thick of practical inquiry and problem
solving, this is what we usually mean by it anyway.
