Quantum Reality 3 (cont) – Time 4 – physics B –
metaphysical A:
The previous discussion of Linguistic Tense (
which also continues)
compares to Metaphysical Tense in McTaggart’s A-series (
mentioned below).
More closely allied to his B-series are more
relative than
absolute
references to Time. Expressions in the vein of the more
relative expressions
include “earlier than”, “extended”, “punctual”, :coinciding with”, occuring
wholly within”, “partially overlapping with”. In this B-series there is no
strict marker indicating the Present moment, but a range of Time may include
the Present moment if it is currently ongoing.
To say someone “
dances” [
present perfect] is to locate an
ongoing
event in a Time period that includes the Present. To say someone
danced
[
simple past] is to locate an event in the Past as
completed.
Both statements concern the Past but the former describes an event in terms of
its temporal constituency: habitual, continuous, ongoing, progressive or
non-progressive, having or lacking continued relevance to Present moment. In
this way such “perfect” Tenses are combinations of Tense & Aspect which
relates the even to some other (
unstated) reference point. To say “
will
have been dancing” [
future perfect] locates an ongoing Future
event earlier than some additional reference point. To say “
has been
dancing” [
pluperfect] locates an even in the Past, earlier than
an additional reference point.
When the Aspect is concerned with internal temporal constituency (A-series)
of events & also the temporal relational network (B-series) in which events
& times stand to each other, then unlike Tense the expression is non-
deictic.
When the internal temporal constituency of event, or relation it stands in to
other events & times, is independent of its Time & Tense relation
(B-series) to a Present moment, then the elements of Aspect combined with
elements of Tense produce an overall
deictic result even though the
Aspect is non-
deictic. [
enough of all that bewildering babble]
Now besides Grammatical Tense, there are diverse other ways of locating
events in Time if different languages. Time location can be indicated with
tone, adjectives, nouns with verb endings, & even hand position in some
concept-based sign languages, such as British.
There are various parts of speech that express Time & temporal location,
including Adjectives like
past,
present, future, but
also:
brand-new,
old,
fledgling,
mint
[condition],
experimental,
modern,
latter-day,
up-to-date,
topical,
traditional,
ancient,
bygone,
obsolete,
elapsed,
brief,
outgoing,
punctual,
eventual,
venerable. Then there are Nouns like:
date,
hour,
millennium,
epoch,
morning,
day,
week,
year,
season,
etc. Some such Nouns are proper names like:
January ,
Thursday ,
etc., or general notions like:
tenure,
period,
interim,
lull,
interlude,
adjournment,
perpetuity,
delay,
aftermath,
successor,
occasion,
relic,
fossil.
Then there are Prepositions like:
during,
throughout,
until,
up to,
before,
after,
since; &
Conjunctions like:
when,
whenever,
while; &
other items that function as Prepositions like:
until,
before,
after,
since. There are parts of words, or
affixes that
express Time relationships through Prefixes like:
ante-,
proto-,
pre-,
post-,
ex-,
fore-,
re-(as in
re-build),
neo-,
palaeo-; & also causative suffixes,
such as
-en (as in
frighten) &
-ify (as in
beautify).
There are also tenseless languages like various Southeast Asian languages
including Chinese. This means that in such languages the expression of the
temporal relation between the event & speech act is not grammaticalized.
But as we have seen, this means of referring to the temporal location of an
event is but a small subset of the ways in which a grammatical Tense can be
deictic,
that is: involving implicit reference to the moment of utterance. Tenses can be
imprecise & insensitive to degrees of pastness & futurity. Other
linguistic resources, in both
deictic & non-
deictic terms,
can provide information about the temporal contours of events & relations
between them.
So much for a sketch of Grammatical Tense & its alternatives. All that
must be separated from the other issue of
Metaphysical Tense which
concerns Quantum Reality & the Philosophy of Science in general.
Metaphysical Tense deals with temporal reality as location in the
Past, Present, or Future. A simple date like “
Sep 11, 2001” doesn’t pick out Tense, it doesn’t specify
where “we are” temporally, in the scenario. A term like “ago” picks out Tense,
referring to the Past, in a manner of “non-relational” tenses, giving
properties of Pastness, Presentness, & Futurity in a less explicit way.
One key
Metaphysical question surrounding these issues is regards
strict
Scientific Realism:
“Had humans (
or observers of
any kind) never evolved, would threw have been an objectively Present
moment, & absolute distinction between Past, Present, & Future? The Yes
or No answer to that question is one way to distinguish 2 major points of view
regarding Tense & Time.
Those who think Tenses are
real think there would have been such a
distinction, even in the absence of any perceivers to designate events as Past,
Present, or Future.
Those who think Tenses are
not real think that temporal reality is
constituted merely by the network of
temporal relations in which
events & times stand to each other, with no Time being marked out as an
ontologically
privileged Present moment (
meaning it has special status). In
other words, no distinction between Past, Present, & Future is
characteristic of Time; no distinction is so projected onto Time, from our
perspective.
The (
A-theorist) holding to an Observer-Independent distinction
between Past, Present, & Future see Time flowing inexorably with respect
Present moment distinction. The
ontological privilege of being the
objective
Present moment continually passes from one moment to next. In this sense
the
A-series is dynamic.
Philosopher, John M. E. McTaggart’s 2-part ordering of positions in Time:
into an (
A-series) [with
tenses & meta-time] is a
Metaphysical
rather than grammatical Tense distinction. Times are thereby ordered in regard
to relative positions in Past, Present, & Future. The (
A-series)
of positions run from
distant Past, through
ever-less-distant
Pastness, to
Present, to proximate (
near)
Future,
& on through to
ever-more-remote Future, a Continuum with a
distinct, though ever-shifting Present zero-point Origin in its 1-D Space.
In contrast, McTaggart’s (
B-series)is less ordered, with Moments
distinguished only into relative positions to each other, in a series from
earlier
to
later. The (
B-theorists) hold to no
objective distinction
between
Past,
Present,
Future. For them there is no
objective
flow of Time. The ordinary distinction we draw between
Past,
Present,
&
Future is explained as as a Projection (
what philosopher
Immanuel Kant called it) with which we perceive reality from an mind
–imposed
temporal perspective, by which we locate events in our
Past,
Present,
&
Future. They would say we wrongly project that perspective on
Time itself, mistakenly concluding that events are
Past,
Present,
or
Future, independent of our knowledge or existence. For (
B-theorists)
there is no associated temporal flow, no
ontological privilege
bestowed upon a
Present moment, no such “privilege” as passes from one
moment to the next for the (
A-series).
The (
B-theorists) admit no genuine
A-properties in the
World, such as:
being Past,
being Present, being Future,
& of finer gradations between them. They do hold to the existence of
analogous properties in the World that would be reducible to, analyzable in
terms of
B-relations such as:
being earlier than ,
being
simultaneous with,
being later than. It just doesn’t work that
way for the (
B-theorists).
For the (
A-theorists) times & events are constantly change with
respect to those
A-properties they possess, their
futurity,
which they shed to acquire
Presentness, which is instantly shed to
acquire
Pastness. This acquiring & shedding of
A-properties is,
for (
A-theorists), the passage of Time.
For the (
B-theorists), there are no
A-properties in the
World. Their
B-series consists only of temporal relations of
Precedence,
Succession, &
Simultaneity.
In one modified (
B-series), a “present moment” is added to the
pattern of events to capture some of what the A-theory thinks Time is like. But
for the (
A-theorist), the (
B-series) lacks their essential
feature of time, the true
distinction between
Past,
Present,
&
Future, so it would add this feature to the
B-series to
generate an
A-series. Thus different kinds of linguistic expression
for locating events in Time (
as reviewed previously for Grammatical –
Linguistic Tense) can also be used to represent Time as conceived
Metaphysically
by the
A-theory & the
B-theory, given the proper
additions or subtractions.
There is thus a correlation between different kinds of
linguistic expression
on the one hand, & the different
Metaphysical views of the nature
of Time on the other hand. But this correlation cannot resolve the
Metaphysical
debate about the nature of Time. We previously noted that some
linguistic
Expressions of temporal location were
deictic –
that is with reference point in Time that is dependent on context in which the
expression is used. If we pick out & refer to some feature of context of
utterance, [
here,
you,
I,
me,
over
there,
that one,
the next one], such can be
deictic
in Grammatical Tense. Such context locates the temporal event that a sentence
is about. It is labeled with some time relative to the time of utterance. Thus
the meaning of
grammatically tensed sentences is dependent on the
temporal context in which they are uttered. Those previously mentioned
lexical
items like
now,
today,
yesterday, &
tomorrow
locate the event at a particular Time in an
A-series. The infinite
number of additional
lexically composite expressions in an (
A-series)
further diversify a “tensed sentence” that is
grammatically tensed.
In some sentences, however, there can be non-
deictic expressions
for locating events in Time, such as:
after dinner,
moments before,
at the start of, or any kind of
date. Those non-deictic
expressions convey no information about (
A-series) locations. But a
combination of non-
deictic expression with
deictic expression
does amount to a net
deictic expression with information regarding the
(
A-series) location of event.
In isolation however, the
deictic quality correlate with the (
A-series),
whereas the non-
deictic correlates with the (
B-series). But
again, any series of temporal positions in
continual transformation,
imply temporal perspective of the person uttering, & thus constitutes an (
A-series)
ordering of events. Contrariwise, ordering a series of temporal positions by
way of
2-term relations that are
asymmetric,
irreflexive,
&
transitive, such as: "comes before" (
precedes)
& "comes after" (
follows) accords with the (
B-series)
of Time.
