Commentaries and Reflections
Commentary by Paul Harvey:
“Direct observation involves selective ascertainment through the senses.
Inference is of three kinds:
– The past shaping the future
– Projecting the whole from the part
– Forming a comparison from a similar.
Authentic authority is trusted words and teachings.”
