The erosion of human memory is a multi-causal phenomenon driven by the physical fragility of recording media, institutional collapse, and the disruption of oral transmission chains. While history is often viewed as a linear accumulation of knowledge, the archaeological record reveals periods of significant contraction where vast amounts of wisdom—from Hellenistic engineering to Indigenous ecological knowledge—were lost.

Material Fragility and Environmental Attrition The survival of ancient texts was heavily dictated by their physical medium. Organic materials like papyrus, used extensively in Egypt, Greece, and Rome, were highly hygroscopic and prone to fungal rot and insect damage, surviving only a few centuries outside arid climates. Parchment offered greater durability but was sensitive to humidity and expensive to produce. The transitio ...
