The transition from Spinoza to Lacan illustrates an immanent view of the world. It is a world where things exist in contingency, but humans create structures that order the world and give it purpose. Then the world appears to be a necessity. What Spinoza and Lacan share in common is this emphasis on structures in an immanent world, whether through ethics or desire. The structural basis of human ethics and desire suggest a common beginning in human nature that deals with the world and tries to make sense of it.
