“Nothing so much assists learning as writing down what we wish to remember”*…

As readers of this blog will have deduced, (Roughly) Daily is a kind of commonplace book…

Commonplace books (or commonplaces) are a way to compile knowledge, usually by writing information into books. They have been kept from antiquity, and were kept particularly during the Renaissance and in the nineteenth century. Such books are similar to scrapbooks filled with items of many kinds: sententiae, notes, proverbs, adages, aphorisms, maxims, quotes, letters, poems, tables of weights and measures, prayers, legal formulas, and recipes… Commonplaces are used by readers, writers, students, and scholars as an aid for remembering useful concepts or facts. Each one is unique to its creator’s particular interests but they almost always include passages found in other texts, sometimes accompanied by the compiler’s responses.

As Steven Johnson points out, commonplace books have a storied history…

Scholars, amateur scientists, aspiring men of letters — just about anyone with intellectual ambition in the seventeenth and eighteenth centuries was likely to keep a commonplace book. In its most customary form, “commonplacing,” as it was called, involved transcribing interesting or inspirational passages from one’s reading, assembling a personalized encyclopedia of quotations. It was a kind of solitary version of the original web logs: an archive of interesting tidbits that one encountered during one’s textual browsing. The great minds of the period — Milton, Bacon, Locke — were zealous believers in the memory-enhancing powers of the commonplace book. There is a distinct self-help quality to the early descriptions of commonplacing’s virtues: in the words of one advocate, maintaining the books enabled one to “lay up a fund of knowledge, from which we may at all times select what is useful in the several pursuits of life.”

The philosopher John Locke first began maintaining a commonplace book in 1652, during his first year at Oxford. Over the next decade he developed and refined an elaborate system for indexing the book’s content. Locke thought his method important enough that he appended it to a printing of his canonical work, An Essay Concerning Human Understanding

The Glass Box And The Commonplace Book

Perhaps because in these interconnected days almost anything seems re-retrievable at a click, not too many bother keeping commonplaces. That’s a shame. Your correspondent can testify that the habit– whether practiced in a book or digitally– is a powerful aid both to learning and to writing.

Happily, there are lots of sources of good advice for getting started, e.g., here, here (source of the image above), and here. There’s even a Masterclass.

As we live and learn, we might recall that it was on this date in 1858 that (prodigious journaler and commonplace keeper) Charles Darwin and Alfred Russel Wallace published “On the tendency of species to form varieties; and on the perpetuation of varieties and species by natural selection” in the Journal of the Proceedings of the Linnean Society. This was the first printed formal exposition of the theory of evolution by natural selection.

Darwin had developed the essential elements of his theory by 1838 and set them on paper in 1844; however, he chose to keep his work on evolution unpublished for the time, instead concentrating his energies first on the preparation for publication of his geological work on the Beagle voyage , and then on an exhaustive eight-year study of the barnacle genus Cirripedia.

In 1856, at the urging of Charles Lyell, Darwin began writing a vast encyclopedic work on natural selection; however, it is possible that the extremely cautious Darwin might never have published his evolutionary theories during his lifetime had not Alfred Russel Wallace, a naturalist born in New Zealand, independently discovered the theory of natural selection. Wallace conceived the theory of natural selection during an attack of malarial fever in Ternate in the Mollucas, Indonesia (Febuary, 1858) and sent a manuscript summary to Darwin, who feared that his discovery would be pre-empted.

In the interest of justice Joseph Dalton Hooker and Charles Lyell suggested joint publication of Wallace’s paper prefaced by a section of a manuscript of a work on species written by Darwin in 1844, when it was read by Hooker, plus an abstract of a letter by Darwin to Asa Gray, dated 1857, to show that Darwin’s views on the subject had not changed between 1844 and 1857. The papers by Darwin and Wallace were read by Lyell before the Linnean Society on July 1, 1858 and published on August 20.
