What instance do you want to call the functions on? This is the part
that confuses me.

I'm going to guess that you want the keyboardHandler to call method of
commandHandler. There's no reason for commandHandler to be a handler
at all then: keyboardHandler is already handling it.
So here is how I would change it:
player = Thing(26,16,'player')
player.brain = Brain()
responder = commandResponder(player.brain,player)
player.brain.add_handlers(
keyboardHandler(player.brain,responder),
joystickHandler(player.brain,responder),
fovHandler(player.brain),
)
