Our work begins with the discovery of the forces of finitude. They appear when the veil of representation that used to cover them falls and subordinates them to a principle of identity. The thought of the French philosopher Gilles Deleuze was born out of the failure of this representation and moves towards an affirmation of difference. However, not all philosophy or science, especially the human sciences, go in this direction. Deleuze constructed an image of thought capable of defining the operation of representation on difference, and called it a dogmatic image, because it undertakes the subordination of reality to the model of Same and Similar. The forces of finitude are discovered in modernity, the forces of life, but they are apprehended through ideas that are too hard, too crude to grasp their true dynamics, to understand their logic, at the heart of which dwells the logical.
