Há anos li um artigo, que não consigo localizar, que estabelecia uma forte relação sobre origem do pensamento consciente com os sinais que uma amiba tem de emitir para se deslocar numa certa direcção em busca de comida.
Há anos que adoptei não o PDCA, o ciclo de Deming, mas a versão que aprendi com Shoji Shiba:
Não começamos com o planeamento (P), começamos com a acção (D à esquerda), e da análise dos resultados da acção calibramos a acção seguinte."It’s tempting to think of our interaction with the world in the following way. First, we perceive the world as it is. Then we decide what to do. Then we do it. Sense, think, act. This may be how things seem, but once again how things seem is a poor guide to how they actually are. It’s time to bring action into the picture.Action is inseparable from perception. Perception and action are so tightly coupled that they determine and define each other. Every action alters perception by changing the incoming sensory data, and every perception is the way it is in order to help guide action. There is simply no point to perception in the absence of action. We perceive the world around us in order to act effectively within it, to achieve our goals and – in the long run – to promote our prospects of survival. We don’t perceive the world as it is, we perceive it as it is useful for us to do so.It may even be that action comes first. Instead of picturing the brain as reaching perceptual best guesses in order to then guide behaviour, we can think of brains as fundamentally in the business of generating actions, and continually calibrating these actions using sensory signals, so as to best achieve the organism’s goals. This view casts the brain as an intrinsically dynamic, active system, continually probing its environment and examining the consequences."
