When I look at a rock, I see the rock and not just its outside surface. Of course, it is the outside layer that is causally responsible for my perception: a typical rock would look the same (except when intense light was shining through it) if suddenly all but the outer one millimeter of it disappeared. Similarly, when I see an event like a ball flying through the air, I see an event that includes the ball's presently flying through the air, even though it is only the temporal parts of the event fractions of a second prior to my perception that are causally responsible for my perception, since it takes light a few of nanoseconds to get to me from the ball and then it takes my visual apparatus rather longer to process it, and I need to process data from two different times in order to get the perception of motion. In both cases the data is processed without my being aware of it, and a rock or an event that includes the present is presented to me. If all goes well, this is veridical, though it could happen that there is no rock but a mere shell or that the ball was annihilated just before I had the perception.
So, in these experiences, when things go well, I have an experience of something extended through space and/or time caused by a very small proper part of the object of the experience. But veridical experiences must be caused by their objects (and in the right way). This means that a whole can count as causing something that is only caused by a proper part. (There are, of course, plenty of non-perceptual examples.) Moreover, notice that the case of the ball flying through the air, then, is a case of something like simultaneous causation when all goes well: a temporally extended event of the ball flying--including its flying now--causes my present perception, and the two events temporally overlap.
But this instance of simultaneous causation seems grounded in a case of non-simultaneous causation: a past temporal part of the ball's flight causing a present experience. That may be so. However, for all we know this non-simultaneous causation could be grounded in a finite sequence of fundamental simultaneous causations between temporally-extended temporally-simple events.
