It’s Saturday morning and‒as I warned you‒I am writing a blog post today.

I just experienced a tiny little frisson of déjà vu, which is always interesting when it happens.  It involved that seemingly obvious, curious sensation that I could remember dreaming about the process of writing this particular blog post, in the location in which I’m writing it, at some time in the past.  Of course, I have no reason to suspect that precognitive dreams are actual things, except occasionally, by coincidence, due to the large number of dreams that happen and the brain’s capacity to model/predict its world with decent accuracy due to the regularities therein.  But déjà vu is still an interesting and sometimes enjoyable experience.

In case you haven’t noticed, mine is very much a stream-of-consciousness kind of blog.  I sometimes wish I were writing something more useful or informative or thought-provoking.  Then I could imagine I was contributing to the world in some way.  I have a wide range of knowledge on lots of topics‒science in general, some physics and cosmology, biology and medicine, some mathematics, a tiny bit of computers, and of course some philosophy (and psychology).

I sometimes regret not having explored philosophy more at an earlier age.  There was a philosophy class in my high school; it was one of my favorite classes, and the teacher was great, but I avoided philosophy in college deliberately.  I had little understanding of how good and useful it‒as well as pure mathematics, not solely for use in physics‒is in improving one’s ability to think about all subjects.

At its “worst” it’s at least analogous to doing calisthenics to get stronger and more fit.  One doesn’t do push ups in order to become a world champion at push ups‒usually‒and one doesn’t do push ups because one expects to become a professional pusher up and to make one’s living that way.  As far as I know, there is no such profession.  One does it to keep one’s body fit so it is more capable of responding to any of a functionally limitless number of specific challenges throughout life.  So it is with the mind, but the mind is far more capable of growth and strengthening than even the greatest athlete’s body has ever been.

I get so frustrated when I hear people whining about, say, the fact that they never use the Pythagorean Theorem in their daily lives, or haven’t used algebra since they left school.  My first reaction when I hear such moans is to think, “If that’s true, then too bad for you; you’re missing out.”

But I also find it noteworthy that most people don’t complain of the fact that they’ve never played kickball or tag or used their sandlot baseball skills in their later life.  Similarly, very few people get jobs playing video games‒there is a vanishingly small few who make at least temporary livings playing video games competitively, but that’s not a reliable long-term strategy for almost anyone.  Such skills are, for the most part, far less useful than those of algebra and calculus‒though I understand that there is some evidence that playing video games can make people better drivers by improving their alertness and response times.

Breadth and depth of knowledge are ends in themselves; they are their own reward, one might say.  When one learns something new, one makes oneself “larger” without taking anything away from anyone else*.  Information can be shared without loss, and one can contain whole universes‒real and/or imaginary‒in one’s mind.  It’s remarkable.

But also, knowledge, even of esoterica, is of practical, basic value.  Insights gained from having studied epistemology or Boolean logic may become useful, unexpectedly, in a business negotiation or a plumbing emergency.  Who knows?  The world is too complex for one to be able to predict the specifics of local events very far ahead of time‒and even the precise knowledge of that fact is based on an originally obscure branch of mathematics and information theory, and was formally born of the use of a “primitive” computer weather simulation.

You cannot fundamentally alter the chaotic nature of reality.  You cannot effectively steer the chaos‒but you can learn to surf on it.  And the more you know and the greater the breadth of your mental skills, the more likely you are to be able to catch the right waves and ride them to someplace you’d like to be.

Anyway, back to what I was saying earlier:  I sometimes imagine myself doing a more informative or exploratory blog, a discussion of sorts, albeit one-sided.  When I leave it to my stream of consciousness, my blog is often depressing (or at least it’s often depressed).  But I don’t know what people might like to read my thinking about; I have a great deal of difficulty understanding what other people find interesting or engaging, let alone why.  So, if anyone has any general subjects they’d like me to explore, whether truly broad or regarding current events or science news or anything within my relative wheelhouse**, feel free to let me know in the comments…or, I suppose, via Facebook or Twitter.  I don’t like to encourage such things, but these “social media” can be entertaining and even useful in certain rarefied situations.

In the meantime, have a good weekend if you’re able to do so.

*Apart from the tiny, tiny increase in overall universal entropy that all learning entails.  But that’s going to happen anyway, and the entropy created by a lifetime of astonishing erudition is unnoticeably small next to, say, that produced every day simply by the Earth absorbing sunlight, warming up, and releasing higher-entropy heat back out into the cosmos.

**My wheelhouse walls are made of rice paper, so I can easily knock them down and expand that chamber as desired.  I dream of my wheelhouse eventually being as large as the cosmic horizon‒or even larger!  Why not?
