The political, intellectual, and religious developments of the early modern period that gave rise to the Scientific Revolution further contributed to a series of debates about key issues in eighteenth-century Europe and the wider world that came to be known as the Enlightenment. By shattering the unity of Western Christendom, the conflicts of the Reformation brought old religious certainties into question; the strong states that emerged to quell the disorder soon inspired questions about political sovereignty and its limits. Increased movement of peoples, goods, and ideas within and among the states of Asia, Africa, Europe, and its colonies offered examples of shockingly different ways of life and values. Finally, the tremendous achievements of the Scientific Revolution inspired intellectuals to believe that answers to all the questions being asked could be found through observation and the use of reason. Progress was possible in human society as well as science.
