Plotinus
- Born 205 AD
- Studied in Alexandria, Egypt
- Taught in Rome
- Founder of neo-Platonism
- Died 270 AD
|
Neo-Platonism
- Plotinus's interpretation of Plato's thought
- Greatly influenced the thought of Augustine
- Reality is arranged in a hierarchy
- The One (unitary source of all being)
- Mind (location of the Forms)
- Soul (origin of space and time)
- Nature (matter ordered by space, time, and Forms)
- Matter (undifferentiated, lowest kind of being)
- Evil lies in the lower orders and is privation
|
Augustine
- Born 354
- From Tagaste, North Africa
- Bishop of Hippo (395)
- First great Christian philosopher
- Died 430
|
Augustine's Winding Path
- Father was a pagan, mother a Christian
- Began as a Christian
- Became attracted to paganism
- Then to Manicheanism (two Gods: one good, one evil)
- Then to skepticism
- Finally returned to Christianity, through Plotinus, who explained evil as privation
|
Augustine's Contributions
- Brought Greek philosophy to Christianity, giving it greater intellectual resources
- Defended Christian doctrine against various heresies
- Argued against skepticism: one cannot doubt that one exists and one has the thoughts one does when doubting
|
Creation
- The Old Testament states that in the beginning, God made heaven and earth
- If a thing is variable, then there was something that did not exist before
- If there was something that does not exist before, then that thing was made
- Heaven and earth are variable, and hence made
- They clearly did not make themselves, since they would have existed before they existed
|
The Word
- God did not make the world like an artist, who gives form to pre-existing matter
- Heaven and earth were not created in heaven and earth
- There is no pre-existing material for creation; only God exists primoridally
- It is not by uttering words, for something would have existed as medium
- So creation is by a Word co-eternal with God
|
Misunderstanding Eternity
- An ancient error is to ask what God did before creation (e.g., rest)
- But a new movement of will by God would contradict God's eternal substance
- Another error would be to ask in consequence why the world has not existed eternally
- This error betrays ignorance of what eternity is
|
No Time Before Time
- Eternity stands forever and what is eternal is always present
- Time does not stand and moments of time are not present all at once, and hence are not eternal
- God made nothing before making heaven and earth
- If there was time then, God had already made time
- If there was not time then, there was no "before then"
|
What is Time?
- Past time depends on things passed
- Future time depends on things approaching
- Present time depends on things being
- The present recedes into the past, so time is only by tending toward non-being
- This raises paradoxes
- How can the past be long ago, when it no longer is?
- How can a stretch of time be long, when only one of its moment is?
|
Past, Present, Future
- It seems that only present time can be measured, since the past and future are not
- Perhaps the past and future do not exist
- Or maybe time comes from and goes to a secret place, seen only by prophets
- If they are somewhere, they should be in the present, since only it is
|
Present Past, Present Future
- The only things that are somewhere are causes and signs of the future, and effects and signs of the past
- It is beyond our knowledge whether God shows the future because it is in some way or only shows a sign
- There is no past or future, but only a present of things present, a present of things past, a present of things future
- The past and future can be in the mind at present
|
Measuring Time
- We cannot measure time by duration, since it would have to be beyond the present
- So we can measure it only in its passing through the present
- This cannot be done by measuring the movement of things
- A day would be one circuit of the sun, no matter how fast
- Time is the condition of movement, not vice-versa
- Time measures motion and rest
|
Extendedness
- Time seems to be extendedness, which we ought to be able to measure
- Probably it is the extendedness of the mind itself
- We try to measure from a starting-point to an ending-point
- But the starting-point ceases to be
- It remains only as an impress in my mind
|
Acts of the Mind
- The mind acts in three ways
- Expecting
- Attending
- Remembering
- What it expects passes, by way of what it attends to, into what it remembers
- A long future is a long expectation of the future
- A long past is a long memory of the past
|
God's Mind
- God has no expectations or memories
- God knows everything unitarily without changing at all
- By analogy, God created the universe without changing at all
