The fractious but potentially fruitful dialogue between legal history and legal theory has been the subject of much recent scholarly attention. Despite this, instances of meaningful engagement over the role of history in legal theorising remain scarce. This is particularly true in respect of normative theorising—the difficult but crucial tasks of critiquing and reforming law—where history is frequently considered to play a relativising role that threatens to destabilise strong evaluation. In this article, I argue that in order to advance the (...) dialogue it is essential to look beyond disciplinary differences and instead focus on the divide between immanence and transcendence, which arises within and also between legal history and legal theory. Reorienting our attention in this way discloses important sources of dissonance but also points towards significant opportunities for cooperation; it is therefore an essential first step in the pursuit of meaningful dialogue, either critical or collaborative.
