Commonplace books, during the Renaissance, were used to enhance the memory. Yeo writes, This reflected the ancient Greek and Roman heritage. In his Topica, Aristotle formulated a doctrine of ‘places’ (topoi or loci) that incorporated his ten categories. A link was soon drawn between this doctrine of ‘places’ (which were, for Aristotle, ‘seats of arguments’, not quotations from authors) and the art of memory. Cicero built on this in De Oratore, explaining that ‘it is chiefly order that gives distinctness to memory’; and Quintilian’s Institutio Oratoria became an influential formulation. This stress on order and sequence was the crux of what came to be known as ‘topical memory’, cultivated by mnemonic techniques (‘memoria technica’) involving the association of ideas with visual images. These ideas, forms of argument, or literary tropes were ‘placed’ in the memory, conceived in spatial terms as a building, a beehive, or a set of pigeon holes. This imagined space was then searched for the images and ideas it contained…. In the ancient world, the practical application of this art was training in oratory; yet Cicero stressed that the good orator needed knowledge, not just rhetorical skill, so that memory had to be trained to store and retrieve illustrations and arguments of various kinds. Although Erasmus distrusted the mnemonic arts, like all the leading Renaissance humanists, he advocated the keeping of commonplace books as an aid to memory.

Ideas on how to analyze and predict network behavior have been informed by concepts arising from the computational and social sciences, which are themselves increasingly concerned with understanding networks. The interesting thing about these ideas is that they work at scales ranging from the molecular to the population level.

Is it possible to avoid the public goods problem altogether?

I’ve alluded to the deeply philosophical nature of this problem; in a sense, it’s politicized within the software communities. Some folks believe that platform developers should shoulder the costs of compatibility, and others believe that platform users (developers themselves) should bear the costs. It’s really that simple. And isn’t politics always about who has to shoulder costs for shared problems?So it’s political. And there will be angry responses to this rant.

By the time Protestantism came along, people had already internalized an individualist worldview. Henrich calls Protestantism “the WEIRDest religion,” and says it gave a “booster shot” to the process set in motion by the Catholic Church. Integral to the Reformation was the idea that faith entailed personal struggle rather than adherence to dogma. Vernacular translations of the Bible allowed people to interpret scripture more idiosyncratically. The mandate to read the Bible democratized literacy and education. After that came the inquiry into God-given natural (individual) rights and constitutional democracies. The effort to uncover the laws of political organization spurred interest in the laws of nature—in other words, science. The scientific method codified epistemic norms that broke the world down into categories and valorized abstract principles. All of these psychosocial changes fueled unprecedented innovation, the Industrial Revolution, and economic growth.

This argument is reinforced by the fact that, at the individual level, we meet many brilliant people who are fascinated by (and often working on) tools for thought, but who nonetheless seem to be making slow progress.

Whether in music (Bach, Lennon), art (Picasso, Bernini), film (Tarantino, Anderson), games (Blow, Lantz), fiction (Kundera, Tolstoy), the most eminent work is usually the result of a single person’s creative efforts. Occasionally it’s a very small group (Eames, Wrights).

Our hope is that once a formal specification for these extensions is settled, this patchset can be used as a base to upstream the changes in the original project.

Networks  of civic engagement increase the potential cost to defectors who risk  benefits from future transactiaction. The same networks foster norms of  reciprocity that are reinforced by the networks of relationships in  which reputation is both balued and discussed. The same social networks  facilitate the flow of reputational information.
