 If Goldman is right, and all high-level simulation processes are guided by imagination, we can then explain why, in our common parlance, we tend to describe high-level simulation processes and outputs in terms of imaginings, images, imagery, etc. More importantly, we can also explain why high-level simulation processes are conscious, under voluntary control, and stimulus-independent. These are, after all, typical properties of imaginative processes. However, there are simulation processes that typically are neither conscious, nor under voluntary control, nor stimulus independent. This indicates that they are not imagination-based. It is to this other type of simulation processes that we now turn.
