II.  WHERE DO WE STAND TO-DAY? 

The self-restriction of scientific inquiry to one-eyed colourblind
observation.  Its effect: The lack of a true conception of 'force'. 

III.  THE ONLOOKER'S PHILOSOPHIC MALADY 

Thought - the sole reality and yet a pure non-entity for the modern
spectator.  Descartes and Hume.  Robert Hooke's 'proof' of the
non-reality of conceptual thinking.  The modern principle of
Indeterminacy - a sign that science is still dominated by the Humean
way of thinking. 

IV.  THE COUNTRY THAT IS NOT OURS 

Electricity, man's competitor in modern civilization.  The onlooker in
search of the soul of nature.  Galvani and Crookes.  Paradoxes in the
discovery of electricity.  'Something unknown is doing we don't know
what.'
