Conscience simulation demands transcending from computability to simulability by an intensive effort on extensive research, to integrate essential mathematical and physical knowledge guided by philosophical goals. A way to begin is hierarchical simulation. Coexistent interdependent hierarchies structure the universe of models for complex systems, e.g., hardware - software ones. They belong to different hierarchy types, defined by simulation abstraction levels, autonomous modules, classes, symbols, and knowledge abstractions. Applying Divide et Impera et Intellige to hierarchy types reveals their importance for intelligent simulation. The power of abstraction is the real measure for the human mind. Turning abstraction into comprehensive construction could be the aim of humanity, the unique God for different cultures of free humans. The way to freedom is by understanding necessity. We have to recall our conscience, to reintegrate our mind, and to remember that society has to assist humans to live among humans. Simulation relates function and structure.
