AFTERWORD: THE SHAPE OF THE TIMELINE
If you scan this timeline from top to bottom, notice:
| Era | Dominant Form of Knowledge | Pace of Change |
|---|---|---|
| Deep Time (40,000–3500 BCE) | Oral, embodied, ritual | Extremely slow (millennia) |
| Classical (3500 BCE–500 CE) | Written, hierarchical, authoritative | Slow (centuries) |
| Medieval (500–1450) | Preserved, theological, monastic | Slow to moderate |
| Renaissance/Reformation (1450–1700) | Printed, contested, individual | Moderate (decades) |
| Scientific Revolution (1543–1687) | Empirical, mathematical, experimental | Accelerating |
| Enlightenment (1700–1815) | Secular, critical, public | Decades |
| 19th Century (1815–1900) | Industrial, evolutionary, ideological | Years to decades |
| 20th Century (1900–1970) | Theoretical, mass-mediated, global | Years |
| Contemporary (1970–present) | Digital, networked, algorithmic | Days to weeks |
The timeline is exponential. What took millennia now takes moments. Human knowledge has never been more abundant — or more fragile.
