According to thomas hobbes social contract, citizens exchange rights for &

  security & stability

Explanation/detail:

Thomas Hobbes published a famous work called Leviathan in 1651.  The title "Leviathan" comes from a biblical word for a great and mighty beast.  Hobbes believed government is formed by people for the sake of their personal security and stability in society.  In Hobbes view, once the people put a king (or other leader in power), then that leader needs to have supreme power (like a great and mighty beast).    Hobbes' view of the natural state of human beings without a government held that people are too divided and too volatile as individuals -- everyone looking out for his own interests.  So for security and stability, authority and the power of the law needs to be in the hands of a powerful ruler like a king or queen.  And so people willingly enter a "social contract" in which they live under a government that provides stability and security for society.

Probably the most famous set of lines from Hobbes' Leviathan book describes what he saw as the natural state of human affairs without government -- one in which every individual had freedom, but that meant it was a situation of "war of all against all," or we might say, every man for himself.  Hobbes wrote:

the industrial development of cities in the ruhr area in the nineteenth century is described. the research was based on english and german language sources. several factors that shaped growth and paths of the cities were categorized and analyzed. they are locations, resources, traditions, entrepreneurs, and technological developments. locations and resources were the most important among them; other factors may be regarded as consequences from locations and resources. among the cities, bochum, essen, gelsenkirchen, and dortmund had the richest resources and most favorable locations in the transportation network and grew to be the largest cities in the ruhr area near the end of the nineteenth century. riverside location was also a favorable factor for the development, as shown in the development of duisburg on the confluence of rhine and ruhr. resource distribution can explain the rise of textile industry, metallurgical industry, and coal and iron industries, and the northward progression of the mining industry. tradition was an important factor for cities such as krefeld, barmen, elberfeld, solingen, and remscheid, which experienced development based on their traditions through the nineteenth century. various entrepreneurs exerted influences within and beyond the local level over the ruhr area. technological development stimulated the northward progression of the mining industry and the deep connection between the coal and the iron industries.
