  Geometric quantization is a natural way to construct quantum models starting
from classical data. In this work, we start from a symplectic vector space with
an inner product and -- using techniques of geometric quantization -- construct
the quantum algebra and equip it with a distinguished state. We compare our
result with the construction due to Sorkin -- which starts from the same input
data -- and show that our distinguished state coincides with the Sorkin-Johnson
state. Sorkin's construction was originally applied to the free scalar field
over a causal set (locally finite, partially ordered set). Our perspective
suggests a natural generalization to less linear examples, such as an
interacting field.
