Planes of Immanence, or the Form of Ideas: Notes on the (anti-)Monuments of Thomas Hirschhorn

What is involved is no longer the affirmation of a single substance, but rather the laying out of a common plane of immanence on which all bodies, all minds and all individuals are situated. This plane of immanence or consistency is a
plan, but not in the sense of a mental design, a project, a program; it is a plan in the geometric sense: a section, an intersection, a diagram. Thus, to be in the middle of Spinoza is to be on this model plane, or rather to install oneself on this plane - which implies a mode of living, a way of life. What is this plane and how does one construct it? For at the same it is fully a plane of immanence, and yet it has to be constructed if one is to live in a Spinozist manner.1
