When we perform a voluntary action, what we select voluntarily is a specific purpose, not a specific movement. (Rosenblueth et al., 1943, p.19) \n\nIn their discussion of purposeful behavior, they used the example of bringing a glass of water to one’s mouth in order to drink. The term negative feedback, they explained, signifies that “the behavior of an object is controlled by the margin of error at which the object stands at a given time with reference to a relatively specific goal” (ibid.). Such goal-directed behavior, however, has another indispensable component. In order to “control” the margin of error indicated by the feedback – in the given example this would be to reduce the distance that separates the glass from one’s mouth – the acting subject must decide to act in a way that will reduce the error. And nothing but inductive inferences from past experience can enable the subject to chose a suitable way of acting. \nLet us look at the example more closely. I am thirsty, and there is a glass of water in front of me on the table. From past experience I have learned (by induction and abstraction) that water is a means to quench my thirst. This is the ‘voluntary purpose’ I have chosen at the moment. In other words, I am anticipating that water will do again what it did in the past. But to achieve my purpose, I have to drink the water. There, again, I am relying on past experience, in the sense that I carry out the ‘specific movements’ which I expect (anticipate) to bring the glass to my lips. It is these movements that are controlled and guided by negative feedback. \nWhen I reflect upon this sequence of decisions and actions, it becomes clear that the notion of causality plays an important role in the event. All my decisions to carry out specific actions are based on the expectation that they will bring about a change towards the desired goal.","highlights":Ӷ^"jQuery321057212323343435682":^°°,^"jQuery321057212323343435682":^°°,^"jQuery321057212323343435682":^°°,^"jQuery321057212323343435682":^°°,^"jQuery321057212323343435682":^°°,^"jQuery321057212323343435682":^°°,^"jQuery321057212323343435682":^°°,^"jQuery321057212323343435682":^°°Ӻ,"text":"","order":"mw-content-text","category":"Argumentation2","data_creacio":1575651931509°
