There
certainly appear to be signs that our culture does so. Being unable to
accurately assess the amount of time that has passed, we also seem incapable of
fully appreciating the changes that have taken place over that period. Notably,
we seem to be unable to recognise the amount of change that has taken place in the
epochs and ages before our individual births.
The
pictures that accompany this blogpiece illustrate how dyschronia can distort
our ability to identify changes over time periods extending beyond our own
individual lifetimes.
Our
lifetimes, when measured against the aeons of earth history, are fleeting.
Without the ability to step back from our limited lifeline it is very easy to
miss the significance of change.
Even when the
pace of change occurs exponentially we can miss the significance because we are
only witnessing a very small slice of time. We then project that slice onto our
own relatively short lifetime, much the same way as a single frame of a movie
gives us only a fragment of the entire movie.
Why is
this?
A couple of graphs may help to demonstrate.
Fig 1
shows the graph of an exponential function. As the graph shows, although growth
starts out fairly evenly after a period of time the slope of the curve begins
to steepen, and then steepens very fast.
This graph
is a representational one and, on the x-axis, suggests a timeline stretching
from 2000 BCE through to 2000CE and beyond. Nothing specifically is depicted by
the curve. It is simply an indication showing what happens under exponential
growth. It could be any of the following: population, resource use, carbon
emissions, species extinction, etc.
The blue sided
rectangle is intended to represent an individual lifetime. (Please note that
this is not to scale.)
Fig 2 is
the rectangle in Fig 1 extracted and stretched along an x-axis commensurate
with the x-axis of Fig 1. This is to symbolise how an individual lifetime is
perceived versus that of some 4000 years.
The first
thing to notice is that the gradient of the curve in Fig 2 is significantly
flatter than that of Fig 1. Thus, when change is viewed simply against one’s
own lifetime, any change may seem to be linear and not changing especially
quickly.
To push
the metaphor further, it can be noted that against the background, the width of
the curve in Fig 2 is much greater than it is in Fig 1. We could interpret this
to mean that the individual whose life course this depicts views themselves as
more significant than is suggested in Fig 1.
Without
stepping back and seeing a wider picture, our sense of time can become
condensed into the years that have elapsed since our birth and maybe a decade
or two before that if we listened to the stories of our parents, uncles, aunts,
and grandparents.
The danger
in this way of perceiving time and the changes that occur is that we miss how
significant those changes are and hence, fail to act in ways that prevent or
forestall any hazardous changes.
Those who
are able to stand back and look at a longer timeframe are able to notice the
steepness of the curves of exponential growth. Sadly, it seems, when these
hazards are pointed out, many will deny the hazard because they are viewing
time only from within their own narrow timespan.
Sigh!
