example? lets see... ...when we switch on a light, there are a number of possible explanations for what is happening. Received wisdom is that by throwing the switch we complete an electrical circuit which allows a current to flow through the filament in the light bulb and it glows so hot and brightly that the room lights up! Alternatively, it may be that the filament gets a sudden urge to consume energy (perhaps its hungry), so it telepathically manipulates the nearest human being to get him or her to throw the light switch and let the current flow. The fact that it also illuminates the room for the benefit of the human being is merely its way of saying "thank you".  This is thus a symbiotic rather than parasitic relationship... Each of those is a philosophically meaningful proposition. Which do you prefer? The simpler one? So does Occam!
