"Most important to Gough in reconnecting people with their innate ability to draw is reconnecting them with whole parts of their brains he believes are neglected when visual intelligence isn’t cultivated. Drawing, he says, is a form of “abductive reasoning,” the least precise but also most open-ended form of logical inference. Instead of reaching for one right answer, Gough says, “you activate the parts of your brain that let you think all the way around a subject."
Abductive Reasoning-- (also called abduction, abductive inference or retroduction) is a form of logical inference which goes from an observation to a theory which accounts for the observation, ideally seeking to find the simplest and most likely explanation. In abductive reasoning, unlike in deductive reasoning, the premises do not guarantee the conclusion. One can understand abductive reasoning as "inference to the best explanation".
