PRINCIPLE OF UNDIFFERENTIATED ENCODING
the brain does not
perceive light, sound, heat, touch, taste or smell. It receives
only neuronal impulses from sensory organs. Thus the brain does
not "see light," "hear sounds," etc.; it can perceive only "this
much stimulation at this point on my body." The practical
consequence is that all perceptions, let alone "thoughts," are
deductions from sensory stimuli. They cannot be otherwise. All
observations are therefore partly the function of the observer.
This situation renders complete objectivity impossible in
principle. (Heinz Von Foerster, "On Constructing a Reality.")
