With this end of the year we are remembering our colleague Marius Backmann, who tragically passed in September 2025.
We’re honored to share that his paper “How Thick is Now? The Prospects of Thick Presentism” has been published posthumously in Metaphysica.
We are thinking of you, Marius. ✨

He's been an inspiration way back during my MA, and I'm still amazed at how kind, constructive (and in retrospect so patient!) he was when I had the privilege to meet him some years later.
