Evidence is to knowledge
as office to power.

"appearance from which inferences
may be drawn," "ground for belief,"
from ex "out, out of, fully"
and videre "to see".

"a post to which certain duties
are attached," literally "work-doing,"
from ops, "power, might, abundance, means"
and facere "to make, to do".

We seek a science
based on evidence
and a policy
bounded by office.

We want a ground
on which to believe.
We want desire
tied to a post.

So do not ask your leaders
for evidence-based policy.
Keep them office-bound,
mindful of their duty.
