Insights on Being Well-Read

What is the true point of a bookish life? Note I write “point,” not “goal.” The bookish life can have no goal: It is all means and no end. The point, I should say, is not to become immensely knowledgeable or clever, and certainly not to become learned. Montaigne, who more than five centuries ago established the modern essay, grasped the point when he wrote, “I may be a man of fairly wide reading, but I retain nothing.” Retention of everything one reads, along with being mentally i...

 Childlike Curiosity is a Virtue

As a species, humans manifest a quality called neoteny, the retention of juvenile characteristics into adulthood. Neoteny has physical ramifications—scarce body hair and a flat face are two examples—but it also has neurological ones. Namely, we have an extraordinary capacity to continue learning throughout life. If neoteny helps to explain our ability to learn, researchers are now figuring out what drives us to take advantage of it. In 2008, a group of scientists set up a novel fMRI stu...

 Lecturing is Easy, Teaching is Hard

Lecturing after a fashion is easy enough ; teaching is a very different affair. ... The transmission of ideas from one mind to another, in a simple unequivocal form, is not always easy ; but in teaching, the object is not merely to convey the idea, but to give a lively and lasting impression; something that should not merely cause the retention of the image, but in such connection as to excite another process, ' thought.'

 No Need for Erroneous Assumptions in Science

The laws of nature, as we understand them, are the foundation of our knowledge in natural things. So much as we know of them has been developed by the successive energies of the highest intellects, exerted through many ages. After a most rigid and scrutinizing examination upon principle and trial, a definite expression has been given to them; they have become, as it were, our belief or trust. From day to day we still examine and test our expressions of them. We have no interest in their reten...

 A Succinct Definition of a Meme

For something to count as a replicator it must sustain the evolutionary algorithm based on variation, selection and retention (or heredity). Memes certainly come with variation - stories are rarely told exactly the same way twice, no two buildings are absolutely identical, and every conversation is unique - and when memes are passed on, the copying is not always perfect. As the psychologist, Sir Frederic Bartlett (1932) showed n the 1930s, a story get a bit embellished or the details are forg...
