  By ascribing a complex anticommuting variable $\zeta$ to each basic {\em
property} of a field, it is possible to describe all the fundamental particles
as combinations of only five $\zeta$ and understand the occurrence of particle
generations. An extension of space-time $x$ to include property then specifies
the `where-when and what' of an event and it allows for a generalized
relativity wherein the gauge fields lie in the $x - \zeta$ sector and the Higgs
fields in the $\zeta - \zeta$ sector.
