On the Eternity of the World
This short treatise asks whether a creation wholly dependent on God could nevertheless lack a beginning in time. It distinguishes causal dependence from chronological priority.
Understanding the text
Written around 1270 amid university controversy, it does not deny the Christian doctrine of a beginning; it examines whether philosophy can demonstrate one.
Key points
- 01
Dependence
A cause can explain an effect’s existence without necessarily preceding that effect in time.

Time

Faith and proof
Believing in a beginning does not mean reason alone proves an eternal world logically impossible.
How to read it
