Welcome to Ex Uno Plures! EUP is a peer support site for people who experience forms of multiplicity or plurality, now in its sixteenth year. Known medically as Dissociative Identity Disorder (formerly Multiple Personality Disorder) when it disrupts a system’s everyday life, multiplicity is the subjective experience of having more than one conscious entity in a brain.
We view our plurality as a kind of neurodivergent experience that is influenced by trauma and the creative process, and all our articles are written from that standpoint, rather than one focused on curing multiplicity. We’re not anti-psychiatry, though—if you believe you need professional support for your system, we encourage you to seek it out.
If you’d like to know who’s behind all this, Ex Uno Plures is run by members of Plures House (formerly the Fen Group and briefly Sylvan System), who have been doing plural self-advocacy online since 2007. Read our FAQ to learn more, check out our individual bios, and find out what we believe about our multiplicity.
A few disclaimers: We are not mental health professionals and cannot provide medical advice, only peer support. Please consult a therapist or psychiatrist if you need expert support. Some of our posts may contain adult content, which we will mark with ’18+’. It is rare for us to discuss traumatic content in detail, so we will not use content warnings for mere mentions of abuse without elaboration. We try to keep it under control in most of this site’s content (except in ranty articles or our audio plays), but we swear a lot. (If you interact with us in person, you’ll learn this very quickly.)
