## Influence and Legacy

### Medieval Period

- Reintroduced to Europe in the 12th-13th centuries

- **Political theory**: influenced constitutional thought

### Criticisms
- Some scientific views were incorrect (e.g., spontaneous generation, geocentrism)

- Emphasized the importance of finding purpose and meaning (telos)

Aristotle's systematic approach to nearly every field of knowledge available in his time makes him one of the most influential thinkers in human history. His empirical methodology helped lay groundwork for modern science, even where his specific conclusions were later overturned.
