  • This is only called 'flying' in countries ruled by repressive governments - in free countries, flight does not involve being attached to a stationary object.

  • lol! Good one! :-)

  • DORK BATTLE ROYALE!

  • This does not imply a homunculus, as, for example, the modulation may be dependent on certain motivations of the animal which, in part are in turn modulated by environmental stimuli.

    Hope that clarifies the issue somewhat?

  • 'Control' in this context is used to convey a difference to 'fixed'. In a system such as the weather, most essential parameters governing it are fixed (they are physical parameters of, e.g. temperature dependence, friction, heat capacity, etc.). I could also have used 'modulate' instead of control, in order to emphasize that parameters which determining the nonlinearity in other systems can be changed in the brain and by the brain.

  • Wrong. "Control" is a conventional term that maps inputs to outputs. It simply describes a mathematical process of a cascade of events to either a stable or unstable configuration.

    There's no reason to say that a brain "controls" its behavior and a weather system does not.

    In any case, your argument is a homunculus argument. Labeling some part of the brain that controls another part of the brain. Well, what controls the part that controls the other part?

  • Good question! The analogy to other chaotic system fails where the brain controls the parameters in specific circuits to control their nonlinear properties. In this view, the brain controls its own nonlinearity, which makes it fundamentally different from other, mathematically related systems.

  • I looked for the free will very carefully, but all I saw was a stuck fly.
