Lissitsky\u27s spatial and architectural work anticipates the contemporary fascination with expanded fields of activity that have resulted in transdisciplinary approaches to research and the role of practice-led research. This paper will discuss Lissitzky\u27s suprematist perspective in relation to contemporary practices - under the rubric of the "diagram" - that re-imagine and enact the relationship between the built surround and embodied cognition. Lissitzky\u27s work will serve as the starting point for a discussion of contemporary practitioners and theorists working across philosophy, cognitive science and built environment in order to draw out, through the act of diagramming, life on new terms.<br /
