As Europe moved toward the modern age, three thinkers each broke sharply from medieval assumptions about power, knowledge, and human nature.
Ethics & Philosophy
Machiavelli, Bacon and Hobbes
A shift toward viewing politics, science, and human nature through observation, not doctrine
Machiavelli
The Prince — political power
Argued rulers should prioritize effective power over conventional virtue
His name became shorthand for ends-justify-the-means strategy
Debated: cynical advice, or a realistic account of how power works?
Bacon
Empirical method — science
Championed observation and experiment over tradition alone
“Knowledge is power” — linked science directly to human control
Laid groundwork for the later Scientific Revolution
Hobbes
Leviathan — human nature
Life without government: “solitary, poor, nasty, brutish, and short”
Justified strong sovereign power to prevent that chaos
Social contract theory influenced centuries of later thought
Must Know
- Niccolò Machiavelli, in *The Prince*, argued rulers should prioritize effective power over conventional moral virtue, if the two conflicted.
- Machiavelli’s name became shorthand for pragmatic, ends-justify-the-means political strategy, often called “Machiavellian.”
- Francis Bacon championed the empirical scientific method, arguing knowledge should be built through observation and experiment, not tradition alone.
- Bacon famously wrote that “knowledge is power,” linking scientific understanding directly to practical human control over nature.
- Thomas Hobbes argued in *Leviathan* that without strong central authority, human life in a “state of nature” would be brutal and chaotic.
Good to Know
- Hobbes described life without government as “solitary, poor, nasty, brutish, and short,” justifying strong sovereign power to prevent that outcome.
- Bacon’s method laid groundwork for the later Scientific Revolution, shifting authority from ancient texts toward direct empirical testing.
- Machiavelli’s work is debated: some read it as cynical advice, others as a realistic description of how power actually functions.

Great to Know
- These three thinkers collectively mark a shift toward viewing politics, science, and human nature through practical, observation-based reasoning rather than inherited doctrine.
- Hobbes’s social contract theory, justifying government through mutual consent for security, influenced centuries of later political philosophy.
- Their combined legacy shows the “Age of Science” wasn’t only about natural science, but also a broader shift in how power and society were understood.
