Review Questions

• How did Anaxagoras’s introduction of 'nous' change the way philosophers approached understanding the cosmos?
  • Anaxagoras's introduction of 'nous' as a cosmic organizing principle marked a pivotal change in philosophy, moving away from mythological explanations towards rational inquiry. By suggesting that an intelligent force governs the universe, he encouraged subsequent thinkers to seek natural explanations for phenomena rather than attributing them solely to divine intervention. This shift laid essential groundwork for later philosophical and scientific exploration.
• In what ways did Anaxagoras's ideas about celestial bodies differ from those of his predecessors?
  • Anaxagoras challenged the prevailing belief that celestial bodies were divine entities by proposing that they were composed of the same substances as terrestrial matter. This perspective suggested that the cosmos operates under consistent natural laws rather than being influenced by divine whims. Such an idea significantly impacted subsequent philosophical thought, emphasizing a more scientific understanding of the universe.
