I kind of felt like I had wandered into an alternate universe upon reading Scarry's bit about flowers.  I haven't noticed that flowers are oft-used examples of imagination.  Nobody I know talks to excess about flowers or can describe them in great detail.  I can't imagine any flowers better than I can imagine horses.  It seems to me that she cherry-picked literary examples pertaining to flowers and wrote based upon her own imaginative preferences.

Scarry's statement that imaginings can be moved to anywhere and are not just limited to the forehead was somewhat of a revelation to me.  I suppose I've just never thought of doing that; every time I imagine things it's either up in my head, or superimposed on the inside of my eyes (so to speak).  Trying her method seemed to work, though, meaning that my idea of  imagination was based upon society's picture, rather than reality.  This has some interesting implications about the rest of the supposed structure of my mind, though it's impossible to tell what's accurate and what isn't.  It seems that this sort of thing would make study of cognition difficult; it's hard to tell which processes are biologically defined and which are shaped by outside factors, although perhaps this could be controlled for by testing across various different cultures.

Regarding the Schooler and Small article, the notion of "mind wandering" occurring against one's will is interesting to me.  They specifically say "Mind wandering may occur as a consequence of trying to avoid it".  Why does this happen?  It seems strange that our brains are capable of acting in ways that we don't wish them to, but everyone experiences this(Don't think of a pink rhinoceros).  Our limbs don't spastically flail without our express will (under normal circumstances in a healthy human); why does our brain seemingly act without our permission?  I think part of the answer to this lies in the fact that a lot of the decision making in our brain may happen on a subconscious level; there have been studies where researchers can predict a subject's decision based on subconscious activity before the subject themself is aware of deciding.

Conjecture - This, to me, implies that our brains are biological organs, and that our notions of conscious control are mainly illusory.  Consciousness as humans know it is a fairly recent evolutionary development; however, for millions of years, our ancestors were making decisions without any consciousness required.  It's likely that these unconscious decision-making processes are still in place and dictate more of our choices that we'd like to think.
