The Reformation enabled the Enlightenment not because its doctrine was inherently progressive—early Protestantism was often fundamentalist—but because it broke the Catholic Church's intellectual monopoly. This fracture created a marketplace of ideas where different philosophies could compete, and forced societies to find ways to coexist with disagreement.

Pre-modern societies, including the U.S. founders, based legal and social structures on "natural law"—an understanding of inherent human nature. The modern left's rejection of this concept leads to policies that ignore reality, such as denying innate human tendencies like greed, which ultimately fail.

Major philosophical texts are not created in a vacuum; they are often direct products of the author's personal life and historical context. For example, Thomas Hobbes wrote 'Leviathan,' which argues for an authoritarian ruler, only after fleeing the chaos of the English Civil War as a Royalist. This personal context is crucial for understanding the work.

In an era defined by religious warfare, John Law's conversion from Protestantism to Catholicism was a pragmatic business decision, not a spiritual one. This illustrates a remarkably secular and free-thinking mindset, treating religion as a political necessity rather than a deeply held conviction.

Machiavelli, raised on the ideal that reading Cicero would create good rulers, watched as educated leaders like the Borgias started horrific wars. He concluded the 'education by osmosis' model was flawed and proposed using history as a dataset—a 'casebook of examples'—to systematically analyze what worked, effectively inventing modern political science.

Governments originate from a collective need to organize and control violence for defense. However, this very concentration of power is predisposed to become oppressive, reflecting a cyclical pattern in human history where freedom is lost to tyranny, regained, and then threatened once again.

Political ideologies like socialism consistently fail because they are not stress-tested against human nature. People inherently resist ceding their individual will and autonomy, even to a system promising a perfect outcome, leading to coercion.

The Enlightenment offered a nuanced view of human nature, rejecting both the religious doctrine of inherent sinfulness and Rousseau's idea of a pure 'noble savage' corrupted by society. Instead, thinkers like Adam Smith proposed that humans are fallible but can be improved and socialized through societal living, a foundational concept for modern liberalism.

To define government's role, one must first define government itself. Its only unique characteristic is the legal power to apply force. Therefore, its functions should be strictly limited to things society needs but individuals cannot accomplish voluntarily, such as national defense, border control, and some basic infrastructure.
