What We Can't See And Why It Matters

I have an appreciation of science,
even though it is a subject 
in which I was bad by design
through how I was taught it.

One reason I like my science
is because, absurd as it might be,
it has units of measurement
for things that public can be told about
where they will never see, directly,
the thing in itself. Only it's effect.

Science has built those units of measurement
into it's vocabulary which helps people believe
in what scientists can never directly see,
and yet make seem rational in conversations.

I can't say that holiness and eternity 'don't exist',
nor can I say that whether, if those concepts had units
of measurement more people would place more store by them
than they did before when they believed without measure.

All I know is that in so far as they are known to exist
their existence is defined by how they defy language.
