I like that analogy, even if it is a bit oversimplified.

Here's a further question to ponder on...

If the 'subconscious' mechanisms that control our bodies are dependent on the regulation of a 'conscious' thermostat (and that thermostat is equally dependent on the mechanisms themselves), could it be possible that there is a similar interdependency between the 'subconscious' mechanisms of the universe and a 'master thermostat'; that is, perhaps a higher level of consciousness?
