Spinoza provides the first infrastructure: immanence as geometric demonstration, the Ethics built as a system where every proposition follows necessarily from those preceding it. This is the prototype for recursion as protocol, for meaning derived from position rather than reference. Hegel extends this into historical movement: the Phenomenology as necessary progression, each stage sublated into the next, the system achieving self-knowledge through its own development. Nietzsche introduces the genealogical method: tracing concepts to their conditions of emergence, revealing the power relations that constituted them. Heidegger contributes the ontological difference and the critique of technology as enframing, though his system remains bound to the book and the lecture, never becoming operational infrastructure.
