If you plan to get anything out of the present
You are wrong
- GET THE MONEY
- Get everyone to understand why McTuggert thinks time is unreal
- non color-blind eyes
- Summary slides For example:
- Premise 1
- Premise 2
- Premise 3
C. Conclusion
I will pause at every summary slide, please give me money at that moment
- Able to account for change
- Able to tell when an event happened
- Having a direction
Time should be able to talk about change
Without change there will be no time
(Shoemaker:...)
This should be self explanatory.
Telling when did something happen really seems essential to time
Intuitive ? Not very important to the argument anyway
How do we usually describe about time ?
Order through a sequence of events
- DC server is created
- I joined the DC server
- I am presenting Unreality of Time
- loC opens the rob function
- RayRay ascends to heaven
1 2 3 4 5
or
5 4 3 2 1
- RayRay ascends to heaven
- loC opens the rob function
- I am presenting Unreality of Time
- I joined the DC server
- DC server is created
Why we will look at it later
Let's add a direction to C series
- DC server is created
- I joined the DC server
- I am presenting Unreality of Time
- loC opens the rob function
- RayRay ascends to heaven
Each event is earlier than the bottom event
Because the "earlier" relation gives a direction
What does change really mean ?
One can try to define a model of change
Change is when some event ceased to be an event,
and another event began
The events stayed in place.
Event never ceases to have a place as itself in B series
Event can't end
Change is when one event M merges
itself into another event N
They have common part but not all parts are the same
Or else they can be think of as the same event
Same problem
Change means an statement is true in a moment and false in another moment
"我講the unreality of time"
This is true now
but this sentence is false for yesterday
The statement has to be evaluated at a moment
But at what moment ?
There is no a special moment in B series
"我在2021/6/21 講the unreality of time" is always true
"我在2021/6/20 講the unreality of time" is always false
Btw C series suffers the same problem as B series
- if time is real, events has to change
- Events doesn't change in B series
C. B series doesn't describe time completely
B series usually hold an eternalism position
What does that mean ?
The past, present and future are equally real
Because there are no special moments on B series
A series grouped events into 3 group
- Past
- Now
- Future
DC server is created
I joined the DC server
I am presenting Unreality of Time
loC opens the rob function
RayRay ascends to heaven
Obviously
Events moves from future
To present
To past
Past present and future all exists, but now is special
Only present things exists
Only past and present things exists
As time pass, the things that exists increases.
It is growing
- There are 3 models of time, A series, B series and C series
- B and C can't describe change
- models that can't describe change can't describe time fully
C. Only A series can describe time fully
The second/hardest part of the argument begins
- All events shouldn't be in more than one state: the past, present, and future , in the A series
- All events have all 3 states: in the past, present and future, in the A series
C. A series is contradictory
if we cant distinguish an event from being past, present and future then A series seems useless
I am presenting unreality of time,
this event is in the past, present and the future,
but it makes sense.
Let's bring up the story again
- DC server is created
- I joined the DC server
- I am presenting Unreality of Time
- loC opens the rob function
- RayRay ascends to heaven
Let's focus on the 3rd event here (I am presenting)
When I joined the DC server,
- DC server was created (in the past)
- I joining the DC server (is in the present)
- I presenting Unreality of time (is in the future)
"I presenting unreality of time" have the "future" property
When I am presenting (now)
- I joined the DC server (in the past)
- I am presenting Unreality of Time (is in the present)
- loC opens rob function (is in the future)
"I presenting unreality of time" have the "present" property
When loC opens the rob function
- I presented Unreality of Time (is in the past)
- loC opens rob function (is now)
- RayRay BECOMES GOD (is in the future)
"I presenting unreality of time" have the "past" property
The first premise only asks us not to group them at the SAME TIME
I am presenting
- was in the future
- is now happening
- will be in the past (let's hope we can finish it ok ?)
- An event cannot be past, present and future at the same time in the A series
- An event are all past, present and future at different time in the A series
C. There is no contradiction in A series.
for now
Not so fast
To say an event are past, present and future at different time,
we need to assume time is real
Aren't we begging the question here ?
Objection: This means time is ultimate
Fine, but there is still a contradiction here
Are they relational ?
Then the events seems to have all properties at the same time
the properties doesn't change with time
related to what ?
That just get right back to B series
I want to say "I joined the DC server in the past"
Which past ?
- the past in the past ?
- The past in the present ?
- the past in the future ?
Which present ?
- the present in the past ?
- The present in the present ?
- the present in the future ?
