we don't think in sentences...

In Nature, not long ago.

"And getting us around is the basic evolutionary rationale of nervous systems. Unlike plants that must take what comes, animals are movers. More sophisticated behaviour emerged with improved capacities to plan, predict and draw on past experience, which improved chances of surviving and reproducing.

This observation motivated neuroscientist Rodolfo Llinás, in his 2002 book I of the Vortex, to propose that, at bottom, thinking is the evolutionary internalization of movement. He meant that thinking is the generation in the brain of images of a future action, and its consequences. And generating these images depends on flexibility in categorizing the current problem as an instance of one kind of event rather than another, which, in turn, depends on memory for past experience. Fundamentally, thinking is neural activity in the service of behaviour (for example, should I flee or fight? Is this attacker weak or strong?). This almost certainly shapes thinking that seems detached from motor preparation (such as, where did Earth come from?).

... If thinking is rooted in internalized movement, it may be more akin to a skill than to a syllogism. Language may not be the "stuff of thought" after all."
