Answer: theory/concept of natural state.
Explanation: Modern times (in philosophy usually associated with René Descartes, who died in 1650, i.e. times when so-called modern philosophy was initiated) mark the beginning of non-religious explanation of society. It means that social philosophers no more refer to Bible and Biblical mythology as their primary resource. Instead of that they work with the fiction of "natural state".
