Andrzej Kmiecik Philosophical Aspects of Computer Research Simulation in Social SciencesIn this article I will try to describe four philosophical aspects of the computer simulation of social behavior. These aspects are the following: methodological, concerning mainly agent based systems and cellular automata systems, epistemological, anthropological and ontological. In conclusion we can state that philosophical analyses of human existence are valuable for making models of human behavior. Keywords: cellular automata systems, agent-based systems, social simulation.
