Historical Context

• Polytheism (400 BC and earlier): Religion involved multiple gods.

• Philosophers: Rise of figures like Plato and Socrates introducing concepts of dualism.

Key Concepts

Materialism and Worldview

• Materialism: The worldview prioritizing matter and motion in understanding the universe.

• Causation in Materialism:

  • Type of Causation: Emphasis on reasons or goals behind events.

  • Design and Plan: Two important aspects concerning the reasons things happen.

    • Events happen for a reason, often leading towards a future goal.

  • Influence of theologians discussing these aspects of causation.

Thomas Hobbes and Epistemology

• Teleological Aspect: Hobbes critically examined the teleological view, where things happen for a purpose.

• Contemporary Science: Shift towards creating models based purely on observable behaviors and material interactions, avoiding appeal to divine causation.

• Hobbes’s Contribution: Advocated for a materialistic understanding, explaining phenomena without invoking design or divine plans.

Structure of Hobbes's Argument

The 'Leviathan'

• 1651 Publication: Hobbes’s most significant work lays foundational ideas for modern materialism.

• Epistemology and Ontology:

  • Explored how human understanding and knowledge is influenced by sensory experiences.

  • This marked a shift from understanding reality directly to understanding our ideas about reality.

The Veil of Perception

• Concept Introduction: The idea that our perceptions are mediated by sensory experiences; encourages questioning the nature of reality.

• Division between Perceptions and Reality: Ideas might be influenced by sensory pressure rather than direct divine insight.

Sensory Experience and Perception

• Source of Ideas: Hobbes argued all mental concepts derive from sensory experiences:

  • Sensory Organs: Our ideas come exclusively from sensations generated by objects interacting with our senses.

  • Primary Qualities vs. Sensible Qualities:

    • Primary qualities: Mathematical properties of objects.

    • Sensible qualities: Colours, sounds, tastes, which arise from the way our senses interact with external materials.

Dreaming vs. Waking Perception

• Similarities: Both dreaming and waking experiences involve sensory information processed by the brain but differ in the nature and consistency of sensory input:

  • Waking: Constant stimulus results in stable and vivid perceptions.

  • Dreaming: Inconsistent sensory input leads to fluctuating and often surreal experiences.

• Hobbes's View on Visions: He viewed visions during moments of inspiration or revelation as brain activity rather than genuine divine communication.

Conclusion

• Materialism's Implication: Hobbes's work suggested that all phenomena can be explained in terms of matter and motion, undermining prior epistemologies based on divine revelation.

• Philosophical Reaction: Hobbes’s materialism posed significant questions about the nature of existence and the reliability of human perception; concepts still relevant in contemporary philosophical debates.

Historical Context

• Polytheism (400 BC and earlier): Early religions that believed in many gods.

• Philosophers: Thinkers like Plato and Socrates began to explore complex ideas about life and reality.

Key Concepts

Materialism and Worldview

• Materialism: A belief that everything in the universe can be explained by matter and movement.

Causation in Materialism:

• Type of Causation: Understanding why things happen based on reasons or goals.

• Design and Plan: Important ideas about why events take place, suggesting events are meaningful and aim towards future goals.

Thomas Hobbes and Epistemology

Teleological Aspect

• Hobbes explored the idea that everything happens for a reason.

• Emphasized observable actions rather than divine influence in explaining the world.

Structure of Hobbes's Argument

• The 'Leviathan': A key book published in 1651, laying groundwork for modern materialism.

• Epistemology: How we understand knowledge through our senses; explaining how we perceive reality differently from how it actually is.

The Veil of Perception

• Concept Introduction: Our understanding of the world is filtered through our senses, leading us to question what's real.

Sensory Experience and Perception

• Source of Ideas: Our thoughts come from sensory experiences:

  • Primary Qualities: Basic properties like shape and size.

  • Sensible Qualities: Our perceptions like colors and sounds, shaped by our senses interacting with the world.

Dreaming vs. Waking Perception

• Differences: Waking life is stable, while dreams can be unpredictable. Hobbes thought visions and inspirations were just brain activities, not divine messages.

Conclusion

• Materialism's Implication: Hobbes argued everything can be understood through physical means, challenging ideas based on religious beliefs. His work raised important questions about existence and how we see reality, ideas that are still debated today.
