& further to yesterday's post:

"He worked usually on large sheets of paper, writing down his thoughts in evident haste, with many alterations, erasures, transpositions, sometimes setting down the words so that they looked more like poetry than prose. ... Each of the large sheets of paper might contain up to nine entries, not necessarily connected, which became, physically, fragments, strips, when Pascal cut them in order to file them, using a system common at the time. He threaded a string through the corner of all the fragments allotted to a given dossier, putting a tag at the top with the title, and tying the string to secure the liasse or bundle.

...

... the heading ‘Nature is Corrupt’, to which neither copy allots any fragments, is clearly integral to the general argument, but the various fragments concerned with corruption (e.g. 449) are scattered over several dossiers."
