Welcome to Dan’s brain
The contents of my head are not useful if they stay in there, so I regularly copy-paste them onto the internet— in fact, into this very website you are reading now. Please, do make yourself comfortable in my mental house. Here you can find notes on most of the things I am thinking about, in the form of a higgledy heap of half-finished notebooks and occasional polished essays, spilling from the imaginary mental bookshelves of my brain.
You might instead be after information about me generally, or what I am doing right now.
My Aunty Val summarises the site updates in her regular emails, which you can subscribe to here:
There is also a Whimsical Blog Map of my writings, hidden behind this little toggle:
