“The division between those who try to learn about the world by manipulating it and those who can only observe it had led, in natural science, to a struggle for legitimacy. The experimentalists look down on the observers as merely telling uncheckable just-so stories, while the observers scorn the experimentalists for their cheap victories over excessively simple phenomena. In biology the two camps are now generally segregated in separate academic departments where they can go about their business unhassled by their unbelievers. But the battle is unequal because the observers' consciousness of what it is to do "real" science has been formed in a world dominated by the manipulators of nature. The observers then pretend to an exactness that they cannot achieve and they attempt to objectify a part of nature that is completely accessible only with the air of subjective tools.”

Context: Now, one sees all that by observing, by being aware, watching, one is aware of all this. Then out of that awareness you see there is no division between the observer and the observed. It is a trick of thought which demands security. Please don't madam, please. And by being aware it sees the observer is the observed, that violence is the observer, violence is not different from the observer. Now how is the observer to end himself and not be violent? Have you understood my question so far? I think so. Right? The observer is the observed, there is no division and therefore no conflict. And is the observer then, knowing all the intricacies of naming, linguistically caught in the image of violence, what happens to that violence? If the observer is violent, can the observer end, otherwise violence will go on? Can the observer end himself, because he is violent? Or what reality has the observer? Right sir? Is he merely put together by words, by experience, by knowledge? So is he put together by the past? So is he the past? Right? Which means the mind is living in the past. Right? obviously. You are living in the past. Right? No? As long as there is an observer there must be living in the past, obviously. And all our life is based on the past, memories, knowledge, images, according to which you react, which is your conditioning, is the past. And living has become the living of the past in the present, modified in the future. That's all, as long as the observer is living. Now does the mind see this as a truth, as a reality, that all my life is living in the past? I may paint most abstract pictures, write the most modern poems, invent the most extraordinary machinery, but I am still living in the past.
