Intention, or intentionality, suggests something purely of the mind and ineffectual, that you are 'intending' to do something but will probably never get around to it - what you will end up doing is a whole host of things that you never really 'intended' to do. It is a hopeless terminology. 'What happens while you are making other plans', is on the other hand an invocation of passivity, like 'stuff happens', and you metaphorically throw up your hands. No, you are always doing stuff, doing what you mean to be doing, its just that most of it is very minor stuff, ancillary to some other project lost in the fog of your accepted goals. You do the multitude of such overlapping doings at every moment and if you want to get some sense of it you need a sociology of purposive actions, of enactments. There are the proletarian enactments, all the many tasks and subtasks needed to keep the show going. We refer to these by such summary terms as washing the dishes, driving to work, etc., but this masks somewhat the immense complexity of the component actions involved. There are also lumpen enactments, like scratching your backside, isolated actions to no end but themselves. Then there are the middle-class ones, making your bread, pursuing your metier, etc., and then there are the upper-class actions, the meaningful or spiritual activities meant to produce a 'deeper' satisfaction, self-described 'ends in themselves' exerting a sort of hegemony over the lower purposes. Well, all this is fine if it help you get through life, but from another point of view, call it the point of view of consciousness, faute de mieux, these are all on exactly the same footing, the same level. They are all nothing but doings, and if you want to know what you are you need to discover yourself in the act. In relation to this 'intention' the simplest actions are the best, stripped of all ulteriority, and these are actions in the world, and where actor and world acted upon are inseparable parts of a whole.
