Explanation:

Machiavelli is credited as the “father” of modern political science. In Leviathan, his principal work, the English philosopher endeavored to establish a new “science of politics” on the basis of the first principles of human nature. While his conclusion — that without an all-powerful Sovereign life would be a “war of all against all” — was largely rejected by his contemporaries, the novelty of his method and his reliance on natural law inaugurated a new era in political thinking.
