What Can/Do We Observe?

What can I observe? What do I observe?

  • What is observable directly without "help"?

  • What is observable with "help"?
    • Is what I observe changed by the "help"
    • Am I using the "help" in such a way that it is "helpful"?

  • What is observable indirectly (by inference or deduction)?

  • Are my observations:
    • accurately recorded?
    • honestly reported?
