Why do we tend towards discretizing things around and within us? Do our senses (for space and time) fool us into this notion all the way into the need for discretizing abstractions themselves, e.g. An abstraction Truth is discretized into a word (a packet) and then we become inclined to encapsulate its meaning within that word. Other examples: I see a table and sense through sight and touch that it is bounded by a physical discontinuity (edges). I hear a musical note and it too is bounded in time. This effect conditions my thinking into seeking edges in abstract thought.

  • I think it's necessary to exist, but what I find fascinating is how insidious and automatic the process is. It is very, very difficult to be continuously aware of the way we package reality into small "packets" and how much doing so changes the way reality occurs to us. – dgo Jan 26 '14 at 18:09
  • I'm not sure if it will interest you within the context you are asking the question, but check Wilipedia for cognitive biases - there are many "human" - (in the sense that you can see it in your life beyond just an abstraction) - illustrations of how our minds collapse around data. – dgo Jan 26 '14 at 18:15
  • @user1167442 THanks for your post. For what it's worth, I like your answer to this other question: philosophy.stackexchange.com/questions/9370/… but unable to upvote. – val Jan 26 '14 at 19:55
  • Excuse me being pedantic, but I'm not sure "Discreditizing" is a word - it would be "Discrediting". Hope you don't think I'm being rude. I mention it because I had to search for it to see if it was a philosophy-specific word that I hadn't heard before. – user2808054 Feb 19 '14 at 15:18
  • Neither word is used. Please re-read :) To discretize essentially means to break up into little bits. – val Feb 19 '14 at 18:34

Don't you think you also tend to build continue representation of obviously discrete objects? Think how films are working: 27 pictures per seconds and there you think it's a continuous movement. Your mind even don't bother to inform your conciseness it's an illusion.

Both discrete and continue approach are used in our everyday representations of the world, as well as in abstract theories.

  • Those seemingly discrete frames are put together into a more complex semantic arrangement - still discrete (beginning and end). Much the same as a sentence is the grouping of words into an object that has higher semantic value(?). It seems hard to think except by using discretized units of thought; yet sometimes happens. Logic seems to be built on units (i.e. edges everywhere!). I realize this is becoming a discussion and Ph.SE reqests neat questions that provide a chance for a structured answer. I wonder what this discussion is in philosophical terms ( i.e. senses bias our thinking). – val Jan 19 '14 at 20:57
  • I didn't try to go toward a discussion. I wanted to point that your question was based on inaccurate premises, or at least it seems to suggests that human have a natural tendency to discretize everything (but you may say it's my interpretation). – psychoslave Jan 19 '14 at 21:01
  • I'm sorry, I don't see how you show that. I assume you meant to finish with "preconceptions". What is an accurate pre - ? – val Jan 19 '14 at 21:08
  • So my point was not to answer if there is more in an interpretation of a set of perception than in a set of stimulus or not, but to illustrate that we also have a tendency to "continualize" things. – psychoslave Jan 19 '14 at 21:12
  • youtube.com/watch?v=zInGEKyRD48 (Brain And Its Automatisms: Unconsciousness Power) is an intersting video documentary, unfortunately in French. May be you get English translation with youtube, I don't know. – psychoslave Jan 19 '14 at 21:33

I propose the reason is a contemporary distrust of holistic thinking, combined with a contemporary obsession with analytic thinking. Consider the persistent myth of right vs. left brain. According to the myth:

     right brain: emotion, intuition, creativity
     left brain: logic, critical thinking, numbers, language

Regardless of it being a myth, I have found that those in philosophy and the sciences have a strong preference for 'left brain activity'. There is a different way to break this down, provided by William James in his Pragmatism: A New Name for Some Old Ways of Thinking. He breaks philosophers down into two categories:

THE TENDER-MINDED Rationalistic (going by 'principles'), Intellectualistic, Idealistic, Optimistic, Religious, Free-willist, Monistic, Dogmatical.

THE TOUGH-MINDED Empiricist (going by 'facts'), Sensationalistic, Materialistic, Pessimistic, Irreligious, Fatalistic, Pluralistic, Sceptical.

Regardless of right vs. left mythology, human psychology does seem to break down into the above two natural kinds—at least, the above two categories form helpful extremes. Now, many modern scientists tend to accept philosophy that is, or is derivative of, Logical Positivism. Today people tend to call themselves 'naturalists' or 'empiricists' or 'physicalists' ('materialist' has gone out of fashion, given the preeminence of thinking in terms of energy in physics today), and while only LP strictly entails being 'tough-minded', many seem to be nonetheless. An example can be found in the article Heretic: Who is Thomas Nagel and why are so many of his fellow academics condemning him?

Roughly, rationalistic philosophy values coherence and beauty over specific matching of reality in all respects, while empiricist philosophy values correspondence with reality over coherence and unity. This needs verifying, but I suspect that rationalistic philosophy has not been credited with much advancing of science in the last several hundred years, while empiricist philosophy has. Massimo Pigliucci suggests this might be a problem:

Lee Smolin, in his “The Trouble with Physics” laments the loss of a generation for theoretical physics, the first one since the late 19th century to pass without a major theoretical breakthrough that has been empirically verified. Smolin blames this sorry state of affairs on a variety of factors, including the sociology of a discipline where funding and hiring priorities are set by a small number of intellectually inbred practitioners. Ironically, one of Smolin’s culprit is the dearth of interest in and appreciation of philosophy among contemporary physicists. This quote is from Smolin’s book:

“I fully agree with you about the significance and educational value of methodology as well as history and philosophy of science. So many people today — and even professional scientists — seem to me like someone who has seen thousands of trees but has never seen a forest. A knowledge of the historical and philosophical background gives that kind of independence from prejudices of his generation from which most scientists are suffering. This independence created by philosophical insight is — in my opinion — the mark of distinction between a mere artisan or specialist and a real seeker after truth.” (Albert Einstein)

Note the "thousands of trees but has never seen a forest". This would be a preference to focus on particulars—an empiricist attitude—over and above a focus on universals—a rationalist attitude. I propose that Albert Einstein, Lee Smolin, and Massimo Pigliucci are correct: we need to find new, productive, holistic ways to think about science, ways which don't just discretize and reduce to basic elements.

The current scientific view of nature is that it is discrete. Discrete particles arising from quantum fields make up the standard model of physics. Continuous systems arising in classical physics are just approximations for when the particle numbers get very large. We are physical systems (including our brain), so maybe the two are related.
