In my experience action begins by taking action.
It must be very interesting operating in a world of involuntary action. Suddenly you are standing in front of the refrigerator without intending to get yourself a beer...
I'm curious as to how you get out of bed in the morning without intending to? How does your car get started without you intending to turning the ignition switch? Once it self starts, does it sense where you want to go? Oh, wait, you don't intend to go anywhere, suddenly you are just going. Are you happy wherever you end up because you never intended to go to a specific place? Someone else in charge of your body? On auto-pilot 24/7?
Interesting conjecture that you can do anything without some intention. Even involuntary actions begin with intention. Please name one human action that does not arise from intention.
