“Reality is in the observations, not in the electron.”

"On the Philosophical Problems in Quantizing Macroscopic Objects"(ca. 1962-1963) as quoted by Morinigo, Wagner, & Hatfield, Feynman Lectures on Gravitation (2002)
Context: This is all very confusing, especially when we consider that even though we may consistently consider ourselves to be the outside observer when we look at the rest of the world, the rest of the world is at the same time observing us, and that often we agree on what we see in each other. Does this then mean that my observations become real only when I observe an observer observing something as it happens? This is a horrible viewpoint. Do you seriously entertain the idea that without the observer there is no reality? Which observer? Any observer? Is a fly an observer? Is a star an observer? Was there no reality in the universe before 109 B. C. when life began? Or are you the observer? Then there is no reality to the world after you are dead? I know a number of otherwise respectable physicists who have bought life insurance.

Context: Thus the man who is responsive to artistic stimuli reacts to the reality of dreams as does the philosopher to the reality of existence; he observes closely, and he enjoys his observation: for it is out of these images that he interprets life, out of these processes that he trains himself for life. It is not only pleasant and agreeable images that he experiences with such universal understanding: the serious, the gloomy, the sad and the profound, the sudden restraints, the mockeries of chance, fearful expectations, in short the whole 'divine comedy' of life, the Inferno included, passes before him, not only as a shadow-play — for he too lives and suffers through these scenes — and yet also not without that fleeting sense of illusion; and perhaps many, like myself, can remember calling out to themselves in encouragement, amid the perils and terrors of the dream, and with success: 'It is a dream! I want to dream on!' Just as I have often been told of people who have been able to continue one and the same dream over three and more successive nights: facts which clearly show that our innermost being, our common foundation, experiences dreams with profound pleasure and joyful necessity.

Science in a Free Society (1978)

The way we use these sources is the key in order to define the required musical result. Without neglecting the acoustic conventional instruments, I spend a fair amount of time dealing with the electronic sources of sound. But please do not think computers! Computers are extremely helpful and amazing for a multitude of scientific areas, but for me, when it comes to creation, they are insufficient and slow. Therefore all of my efforts are to stay away from that beast".

Context: Relativity propped it up, at least gave it the illusion of being there... the way all reality becomes illusory and observer-oriented when you study general relativity. Or Buddhism. Or get drafted.
