The Presocratics and the Early Greek Questions
- Discovery of Nature - humankind can know by reason and observation.
- Separation of idea from object - abstraction
- Opportunities for reflection in a priviledged class
- Knowledge by experience vs knowledge by revelation
- Natural vs supernatural
- Nature in terms of nature, cause and effect elaborated with natural
and observable relations.
- Nature of divinity - underlying truth, divine reason, divine knowledge -
Logos (word, proposition, truth within, reality - all mixed)
- The preoccupation with first principles - Arche (source, principle)
- True knowledge
- Reason - as true knowledge
- Senses and perception
- Being and Non-Being
- Change, motion, coming-to-be
- Form, as in underlying pre-sense truth that frames the reality we
experience. Another answer to the question of what is most real; what is it.
- Matter vs Form. (A table is wood or is something to put books on).
- Underlying truth vs experiential truth.
- Causation
- Divisibility and continuity
- Finite and Infinite
- Bounded and unbounded.
- Roochnik, p12.
- Thales is the first philosopher because he was a
practitioner of logos, or rational thought or speech
- Wheelwright page 13
- Ontology - What is most real and why? Can we trust our senses?
- Cosmology - How the world works as a natural system. Origins and change.
Destiny or purpose.
- Epistemology - How do we know we know, ie, validate our knowledge.
Epistemology is the maturing of philosophy; reflecting on what it means to know.
Asking about "the effectiveness of the instruments with which they have been
provided by nature for getting in touch with the world" - Guthrie.
- Wheelwright p43
- Presocratics began asking what instead of who (the gods),
how instead of why, as in intent or purpose of the gods.
- Roochnik on the early philosophical questions, p8
- Is the world orderly or chaotic?
- Is it a projection of our minds, or dies it exist independently on
its own?
- Can something come from nothing?
- Is anything stable, or is all in flux?
- In the face of death does human life have meaning, and how should we
go about living it well?
Context and Intrepretation
- Wheelwright p15 - Problems of translation
- Wheelwright pp1-12 - The early Greek context
- Wheelwright pp17-39 - Greek religious setting
- Guthrie - Greek ways of thinking
- The influence of language and words on interpretation
- Our interests and frame of mind
- The mathematical order of nature
- A story that will have the cohesion to help us make sense of history
and remember something. Stories give us meaning.
- Roochnik p8-9 - The risks of a "dialectical narrative".
