27. Natural Reality / C. Space / 3. Points in Space
22922
|
We can identify unoccupied points in space, so they must exist [Le Poidevin]
|
22924
|
If spatial points exist, then they must be stationary, by definition [Le Poidevin]
|
27. Natural Reality / C. Space / 4. Substantival Space
22923
|
Absolute space explains actual and potential positions, and geometrical truths [Le Poidevin]
|
27. Natural Reality / C. Space / 5. Relational Space
22928
|
For relationists moving an object beyond the edge of space creates new space [Le Poidevin]
|
27. Natural Reality / C. Space / 6. Space-Time
22931
|
We distinguish time from space, because it passes, and it has a unique present moment [Le Poidevin]
|
27. Natural Reality / D. Time / 1. Nature of Time / e. Eventless time
22917
|
Since nothing occurs in a temporal vacuum, there is no way to measure its length [Le Poidevin]
|
22921
|
Temporal vacuums would be unexperienced, unmeasured, and unending [Le Poidevin]
|
27. Natural Reality / D. Time / 2. Passage of Time / b. Rate of time
22934
|
Time can't speed up or slow down, so it doesn't seem to be a 'process' [Le Poidevin]
|
27. Natural Reality / D. Time / 2. Passage of Time / f. Tenseless (B) series
22938
|
To say that the past causes the present needs them both to be equally real [Le Poidevin]
|
22940
|
If the B-universe is eternal, why am I trapped in a changing moment of it? [Le Poidevin]
|
22939
|
The B-series doesn't seem to allow change [Le Poidevin]
|
27. Natural Reality / D. Time / 2. Passage of Time / g. Time's arrow
22953
|
Time's arrow is not causal if there is no temporal gap between cause and effect [Le Poidevin]
|
22947
|
An ordered series can be undirected, but time favours moving from earlier to later [Le Poidevin]
|
22952
|
If time's arrow is causal, how can there be non-simultaneous events that are causally unconnected? [Le Poidevin]
|
22951
|
If time's arrow is psychological then different minds can impose different orders on events [Le Poidevin]
|
22948
|
There are Thermodynamic, Psychological and Causal arrows of time [Le Poidevin]
|
22949
|
Presumably if time's arrow is thermodynamic then time ends when entropy is complete [Le Poidevin]
|
22950
|
If time is thermodynamic then entropy is necessary - but the theory says it is probable [Le Poidevin]
|
27. Natural Reality / D. Time / 2. Passage of Time / i. Time and motion
22943
|
Instantaneous motion is an intrinsic disposition to be elsewhere [Le Poidevin]
|
22945
|
The dynamic view of motion says it is primitive, and not reducible to objects, properties and times [Le Poidevin]
|
27. Natural Reality / D. Time / 2. Passage of Time / k. Temporal truths
22937
|
If the present could have diverse pasts, then past truths can't have present truthmakers [Le Poidevin]
|
27. Natural Reality / D. Time / 3. Parts of Time / a. Beginning of time
22925
|
The present is the past/future boundary, so the first moment of time was not present [Le Poidevin]
|
27. Natural Reality / D. Time / 3. Parts of Time / c. Intervals
22944
|
The primitive parts of time are intervals, not instants [Le Poidevin]
|
27. Natural Reality / D. Time / 3. Parts of Time / e. Present moment
22942
|
If time is infinitely divisible, then the present must be infinitely short [Le Poidevin]
|
27. Natural Reality / E. Cosmology / 10. Multiverse
22946
|
The multiverse is distinct time-series, as well as spaces [Le Poidevin]
