Still too Busy to Blog Properly….But Hey, Look What I’m Reading!

Tuesday, November 24th, 2009

Were it not for guest posts, November would have seemed like I went on hiatus 🙂  Normal blogging will resume in a few weeks.

I did find time to pick up a few new books to read in the late hours of the night, one of which will be the subject of a book review by a new guest poster.

         

The Genius of the Beast: A Radical Re-Vision of Capitalism by Howard Bloom

The Shia Revival: How Conflicts within Islam Will Shape the Future by Vali Nasr

Nixonland: The Rise of a President and the Fracturing of America  by Rick Perlstein

The only thing these three tomes have in common is that the authors have a penchant for contradicting conventional wisdom, at least to a degree. 

Howard Bloom is an offbeat, pop science to pop culture master of horizontal thinking whose earlier work, Global Brain, I very much enjoyed and highly recommend. Bloom’s intellectual reach is first rate and he is one of the few writers who can take very difficult concepts from wildly disparate fields and tie them together for a lay audience with comprehensible analogies and anecdotes .

I put Vali Nasr’s The Shia Revival on my list back after the high praise Thomas P.M. Barnett gave Nasr in his book, Great Powers – in my experience, Tom does not hand out comments of “brilliant” all that often ( Great Powers, BTW, is also a “must read” book for those interested in strategy and geoeconomics). I am approximately 80 pages in to The Shia Revival and I will say that as a writer, Nasr does not waste time getting to key points in explaining his subject – concise but not simplified.

Rick Perlstein, while far to the Left, has the uncommon quality among leftwingers of working very, very hard at the scholarship of attempting to understand conservatism and leading conservatives ( must be a legacy of attending the University of Chicago). Much like Orangemen in Ulster, eavesdropping on a Catholic mass, I suspect the essence of conservatism eludes Perlstein, but at least he takes the ideas seriously.  That Richard Nixon is Perlstein’s subject is an added draw, since Nixon’s foreign policy was an area of historical research for me. Very interested to see how Perlstein’s take on Richard Nixon compares to that of Robert Dallek and Richard Reeves.

The Internet is Re-Wiring your Brain….in a Good Way

More fodder for the digital vs. dead tree debate:

UCLA Study: The Internet Is Altering Our Brains

….After the initial brain scan, subjects went home and conducted Internet searches for one hour a day for a total of seven days over a two-week period. These practice searches involved using the web to answer questions about various topics by exploring different websites and reading information. Participants then received a second brain scan using the same Internet simulation task, but with different topics.

The first scan of participants with little Internet experience showed brain activity in the regions controlling language, reading, memory and visual abilities. The second brain scan of these participants, conducted after the home practice searches, demonstrated activation of these same regions, but there was also activity in the middle frontal gyrus and inferior frontal gyrus – areas of the brain known to be important in working memory and decision-making.

….The results suggest that searching online may be a simple form of brain exercise that might be employed to enhance cognition in older adults,” Teena D. Moody, the study’s first author and UCLA researcher, said in a statement.

When performing an online search, the ability to hold important information in working memory and to take away the important points from competing graphics and words is essential, Moody noted.

I will be interested in seeing brain scan comparisons between digital natives who were on computers from the time they were toddlers, and the digital immigrants.  My son, for example, learned to read on his own long before pre-school from looking at words on a computer screen ( less “learned” than spontaneously “realized” the symbol-sound-conceptual connection ) while his sister, who had a more traditional exposure to reading, learned later ( more “taught”).

Another difference, while they are both equally skilled at reading, adjusted for an age, she is an avid reader who devours large books (mostly fiction) while her brother reads instrumentally, for knowledge or expository explanations (mostly natural science subjects. Only “Clone Wars” attracted him to read fiction).

This is simply amazing and the ultimate in Orwellian thought police technology ( Hat tip to Bill Petti).

Three Short Reviews

Emergence: The Connected Lives of Ants, Brains, Cities, and Software by Steven Johnson

This classic popular text from 2001 still holds up well as an introduction into the phenomena of emergence and the nature of self-organizing systems. Johnsaon uses a rich array of analogies and historical anecdotes to bring the reader to an understanding how bottom-up, “blind”, systems work and the principles behind them. Highly readable and next to no jargon. Probably due soon for an updated edition though, given the scientific advances in research in network and complexity studies.

How Rome Fell: Death of a Superpower by Adrian Goldsworthy

Superb overview of the decline and fall of Rome with a rejection of the traditional assertions of causations for the end of the Roman empire ( Barbarians, Christianity etc.). Goldsworthy also sharply criticizes the popular idea among postmodern classicists today that the Roman Empire was “really” as strong during the fourth and fifth centuries as it was during the golden age of philosopher-warrior-emperor Marcus Aurelius. Or that there was no fall of the empire at all, just a gentle “transformation” into something new. Goldsworthy discusses the likelihood of Late antquity  “paper legions” of Roman armies which, in any event, scarcely resembled in elan, tactics or fighting strength the ones that Julius Caesar wielded in Gaul.  A tour de force marred only by a weird epilogue that ranges from pedestrian to ( in it’s last sentences) truly awful – was it it tacked on as an afterthought? Did the editor of the rest of the book die before it was completed? Regardless, How Rome Fell is a worthy addition to an collection of popular ancient histories.

The War of Art: Break Through the Blocks and Win Your Inner Creative Battles by Steven Pressfield

A rare, nonfiction book by novelist and blogger Steven Pressfield. The War of Art is a book that I strongly recommend to aspiring writers ( which includes most bloggers) and other people pursuing dreams, not because it is brilliant but because it is profound. Utilizing select personal vignettes and other anecdotes, Pressfield distills in everyday language the essence of what creative people need to understand if they are to succeed – concepts of “resistance”, which seductively undermine your efforts,  and being a “professional”, which is the mindset that will get you there.

Most of the readers of this blog are interested in military affairs to some extent so I will use this reference to explain why I read The War of Art from cover to cover. Pressfield captures the difference in what Col. John Boyd called the question of “To be or to do. Which way will you go?”.  By Boyd’s definition, Pressfield is a doer.

Steven Pressfield blogs on The War of Art of writing every Wednesday.

The First Genocide?

Thursday, July 23rd, 2009

Or perhaps the analogy of Cain and Abel?

Remains Show Human Killed Neanderthal

Newly analyzed remains suggest that a modern human killed a Neanderthal man in what is now Iraq between 50,000 and 75,000 years ago. The finding is scant but tantalizing evidence for a theory that modern humans helped to kill off the Neanderthals. The probable weapon of choice: A thrown spear.

The evidence: A lethal wound on the remains of a Neanderthal skeleton. The victim: A 40- to 50-year-old male, now called Shanidar 3, with signs of arthritis and a sharp, deep slice in his left ninth rib. “What we’ve got is a rib injury, with any number of scenarios that could explain it,” said study researcher Steven Churchill, an associate professor of evolutionary anthropology at Duke University in North Carolina. “We’re not suggesting there was a blitzkrieg, with modern humans marching across the land and executing the Neandertals [aka Neanderthals]. I want to say that loud and clear.” But he added, “We think the best explanation for this injury is a projectile weapon, and given who had those and who didn’t, that implies at least one act of inter-species aggression.”

What is interesting about the disappearance of the Neanderthal is that it is hard to explain simply in terms of competition for resources with early Homo Sapiens, given that the global human population was astronomically low. The Neanderthal too, would have had many physical advantages, given their more robust physiology, over their evolutionary cousins. Speculation has ranged from climate change, to immunological differences to the cognitive and cultural.

Could a key cultural difference have been a propensity of Homo Sapiens to make war? To seek out, rather than avoid conflict?
