In the modern world we are in a paradoxical situation; because although in theory man knows that he can extend his attention to something and then remove it, he very often does not do so. In many areas he does not look at something and then detach from it, and look at something else.Once he has found something to interest himself in, he cannot detach himself from it efficiently, and therefore he cannot be objective. Note that, in most if not all languages, we have words like 'objectivity' which leads people to imagine that they have it, or can easily use it. That is equivalent (in reality if not in theory) to saying 'I know the word “gold”, so I am rich.
