Review Questions

• Explain Thales' significance as the first philosopher in the Western tradition.
  • Thales is considered the first philosopher in the Western tradition because he was the first to attempt to explain natural phenomena through rational inquiry and the use of reason, rather than relying on mythological or supernatural explanations. His focus on understanding the underlying principles and causes of the natural world, rather than simply accepting traditional beliefs, laid the foundation for the development of Western philosophy and the scientific method.
• Describe Thales' cosmological theory and its influence on the Milesian School.
  • Thales proposed that the fundamental substance of the universe is water, which he believed was the source and origin of all things. This monistic view, where a single, fundamental principle underlies the entire cosmos, was a key aspect of Thales' cosmological theory and a defining characteristic of the Milesian School. Thales' emphasis on finding a unifying principle that could explain the natural world influenced the subsequent philosophers of the Milesian School, who continued to search for the fundamental substance or principle that governs the universe.
• Analyze the significance of Thales' accurate prediction of a solar eclipse and its impact on the development of early Greek philosophy.
  • Thales' accurate prediction of a solar eclipse in 585 BCE was a significant accomplishment that demonstrated his advanced astronomical knowledge and his ability to observe and understand natural phenomena through rational inquiry. This achievement challenged traditional mythological explanations for celestial events and showed that the natural world could be studied and understood using reason and scientific observation. Thales' success in predicting the eclipse not only highlighted his own intellectual capabilities but also paved the way for the development of the broader Pre-Socratic philosophical tradition, which sought to provide rational, naturalistic explanations for the workings of the universe.
