Reading the past
object (artifact, site or whatever). These are simply all the fac-
tors in the previous system state which impinge upon the new
state. But in the imposition of meaning content, when the ar-
chaeologist wishes to evaluate the claims that two objects are
likely to have the same meaning content because they are con-
temporary, or that the meanings are unlikely to have changed
within the same phase, the question of scale becomes even
more important. So, from considering temporal similarities
and differences, we are left with the question: what is the scale
on which the relevant temporal context is to be defined? This
question of scale will reappear and will be dealt with later, but
it seems to depend on the questions that are being asked and
the attributes that are being measured.
Similarities and differences can also be noted along the spa-
tial dimension. Here the archaeologists are concerned with
identifying functional and symbolic meanings and structures
from the arrangements of objects (and sites, etc.) over space.
Space, like time, is also qualitatively experienced, as we saw
in chapter 6, and therefore should not be understood simply
as a neutral variable. Normally analysis along this dimension
assumes that the temporal dimension has been controlled.
The concern is to derive meanings from objects because
they have similar spatial relationships (e.g. clustered, regu-
larly spaced). Again, a battery of techniques already exists for
such analysis. It can be claimed that many of these spatial
techniques involve imposing externally derived hypotheses
without adequate consideration of context; however, new
analytical procedures are now emerging which allow greater
sensitivity to archaeological data. For example, Kintigh and
Ammerman (1982) have described contextual, heuristic meth-
ods for the description of point distributions, and related
techniques have been described for assessing the association
between distributions (Hodder and Okell 1978), and for de-
termining the boundaries of distributions (Carr 1984). Indeed,
it is possible to define a whole new generation of spatial an-
alytical techniques in archaeology, which are less concerned
to impose methods and theories, pre-packaged, from other
disciplines or from abstract probability theory, and are more
