Context

“The third period, from the seventeenth century to the present day, is dominated, more than either of its predecessors, by science; traditional religious beliefs remain important, but are felt to need justification, and are modified wherever science seems to make this imperative. Few of the philosophers of this period are orthodox from a Catholic standpoint, and the secular State is more important in their speculations than the Church.
Social cohesion and individual liberty, like religion and science, are in a state of conflict or uneasy compromise throughout the whole period. In Greece, social cohesion was secured by loyalty to the City State; even Aristotle, though in his time Alexander was making the City State obsolete, could see no merit in any other kind of polity. The degree to which the individual’s liberty was curtailed by his duty to the City varied widely.” source
