Defeasible Reasoning

For the last twenty-five years or so, students and colleagues (and colleagues who are fellow students, or students-turned-colleagues) have been asking me questions and which I've gamely tried to answer. We trade questions, mostly with civility, sometimes with a slightly jagged or sharp edge; it can get heated at times, but we learn a lot from each other.

There is one particular problem I've identified, which I personally call the 'textbook problem'. This is best stated as a subconscious tendency to adhere to 'textbook knowledge', which is not reprehensible or to be considered less lacking in authority simply because it is from a textbook, but is problematic because textbooks are always out of date. By the time a textbook is edited and published, it is often a year or two out of date. In some cases, because it is indeed a good textbook, serious revisions do not occur for longer periods of time.

One would think that the quicker publishing that online modes afford should eliminate or reduce the problem. This is not always the case. However, it does bring the horizon closer to the sailor, as it were.

The second part of the problem, however, is that this enhanced access to knowledge doesn't seem to be utilised by a lot of the people I encounter. This is not meant as an insult or belittlement, but is a fact based on my own perceptions. I interact with many people, and in my interactions, find that they haven't used something simple like Google or Wikipedia to find out more about whatever they are supposed to know.

The third part of the problem is that people assume that other people know how to use Google and Wikipedia and all the other wonderful iterations of the information age as manifest in the works of the internet. But because of the second part of the problem, these expectations are sometimes dangerously unfounded and may lead to awkward disappointment.

This is the case with the many people I encounter whose epistemology seems to be based on a stilted sort of hybrid of Plato and logical positivism. Or some vague spirituality. Or other ideas which they got from other people — and strangely enough, didn't bother to evaluate further using internet-based tools. I'm not saying that these tools are better, but they are certainly faster than the ones I grew up with, in most cases. In a pinch, speed has to be a substitute for depth, and often is.

Let's try an experiment. All you TOK students out there, looking for answers to your 2010-2011 TOK Essay Topics and suchlike, why don't you try working your way through this article from the online Stanford Encyclopaedia of Philosophy first? I am very certain that it will yield dividends in the days ahead. I mean, just imagine what the following sentence might mean for the fate of your TOK essay:

"With the collapse of logical positivism in the mid twentieth century (and the abandonment of attempts to treat the physical world as a logical construction from facts about sense data), new attention was given to the relationship between sense perception and the external world."

Now imagine that I was setting the 2011-2012 TOK Essay Topics, and I used that quote, followed by, "Discuss the nature of this relationship, with respect to two different areas of knowledge." Are we having fun yet?

Fun, fun!

Now. The irony in what you've said, I should think...

"Or other ideas which they got from other people — and strangely enough, didn't bother to evaluate further using internet-based tools. I'm not saying that these tools are better, but they are certainly faster than the ones I grew up with, in most cases. In a pinch, speed has to be a substitute for depth, and often is."

...is that people, some of them at any rate, view the internet with a great degree of suspicion, given that it is not usually considered to be a "reliable source" (use of term for lack of a better one). Word-of-mouth trusted, but a failure to continue on to the next step and substantiate claims made via word-of-mouth, then? Not even using a semi-reliable source to back up / check on those claims?

Do people then fail to critically consider what is told to them, and instead simply accept it as a given truth/fact/whatever-term-is-appropriate-insert-here?

Most certainly, the internet and the tools it provides are by no means "better" tools. But strange and convoluted as it may be, it probably is "faster". Given that it's updated so regularly.

Of course, this is only a portion of the entire issue you've laid out before us here.

Now if only more students were like you... :)

The internet is like caffeine. Caffeine makes you smarter. It fends off Alzheimer's. Why?

Simple: Caffeine makes EVERYTHING work faster. So you have more processing speed, and in a given time, you can think more. You have enough time to possibly counter your own bad thinking...

But of course, if you don't make proper use of that faster processing speed, you end up feeling confused because its just meaningless but faster throughput.
