My latest article 'From Habit to Monads: Félix Ravaisson's Theory of Substance' has just been published online. You can find it here.
I've also just sent off the proofs for a piece called 'Monadologies: An Historical Overview' co-written with Pauline Phemister. I'm really looking forward to seeing that one in print.
There are also lots of other great articles on monads currently up on the latest articles section of the BJHP website. I recommend checking them out!
