empirical content is a question of testability
what can be tested?
testability a question of the nature of observation
what is observed is a question
never a fact
a fact is a conclusion of the question of observation
a decision
we observe
what it is we observe is a matter of reflection - i.e.
the body of scientific thought
the point is
the object of observation - the existent
is without content
we assume its existence - as a base line - that it is -
this is OK - necessary
but such is just the fact of its presentation
such is undefined
(like a logical constant)
it's characterization
is a question of reflection
this does no damage to 'the fact of the fact'
it simply makes the point that its revelation is a
conceptual issue
and it is fluid
subject to possible interpretation
the immediate object of perception
is - apart from its conceptual realizations -
unknown
p.s.
observation stripped down - minus any metaphysics
conceptualization
is an event within events
