4.1 Buddhism: core teachings and philosophical developments

Buddhism's core teachings revolve around the Four Noble Truths and the Eightfold Path. These ideas address the nature of suffering and offer a practical guide to liberation. The philosophy emphasizes personal experience and empirical observation in understanding reality.

Buddhist thought evolved over time, with schools like Mahayana introducing new concepts. Philosophers like Nagarjuna and Vasubandhu expanded on original doctrines, developing complex ideas about emptiness and the nature of mind. Buddhism's interaction with other Indian traditions further shaped its philosophical landscape.

  • Illustrates how mental states and actions lead to future experiences
• Challenges the notion of an independent, permanent self (atman)
  • Supports the Buddhist doctrine of no-self (anatman)
  • Emphasizes the dynamic, ever-changing nature of personal identity
• Implies that all phenomena are empty of inherent existence (sunyata)
  • Key concept in Mahayana Buddhism developed by Nagarjuna
  • Refutes the idea of essential, unchanging natures in things or beings

Philosophical and Ethical Consequences

  • Emphasizes the importance of compassionate action

• Crucial for breaking the cycle of rebirth and achieving liberation (nirvana)
  • Understanding dependent origination leads to insight into the nature of reality
  • Helps in uprooting the causes of suffering (craving and ignorance)
• Influences Buddhist epistemology and logic
  • Informs the development of the catuskoti (tetralemma) logical structure
  • Shapes the Madhyamaka school's dialectical approach to philosophical inquiry
• Provides a framework for understanding causality and change
  • Challenges simplistic notions of linear causality
  • Emphasizes the complex web of conditions that give rise to events and experiences
