The idea that there are two opposed world views that may be characterised as ‘techno’ and ‘Eco’ is intuitive. The two belief systems are both viewpoints and standpoints that persuade their devotees which way to interpret a situation, argument or body of observation that may be otherwise either difficult to interpret or prove, or is on a knife edge in the balance of its implications. Such strongly held core beliefs sometimes allow a sliver of doubt to inform and justify a strong opinion.
