The extreme weakness of quantum gravitational effects now poses some philosophical problems; maybe nature is trying to tell us something new here: maybe we should not try to quantize gravity.
Interpretation
The quote reflects on the challenges and philosophical implications of understanding gravity through quantum mechanics.
Richard P. Feynman's quote highlights the profound uncertainties and philosophical questions that arise from the weak observational effects of quantum gravity. He suggests that perhaps nature itself is indicating a need to reconsider our approaches and assumptions about quantizing gravity, urging us to think critically about the fundamental principles of physics.
In practice
During a physics lecture, to introduce the complexities of quantum mechanics.
The philosophical question before us is, when we make an observation of our track in the past, does the result of our observation become real in the same sense that the final state would be defined if an outside observer were to make the observation?
We seem gradually to be groping toward an understanding of the world of subatomic particles, but we really do not know how far we have yet to go in this task.
The first principle is that you must not fool yourself and you are the easiest person to fool.
It has not yet become obvious to me that there's no real problem. I cannot define the real problem; therefore, I suspect there's no real problem, but I'm not sure there's no real problem.
For far more marvelous is the truth than any artists of the past imagined it. Why do the poets of the present not speak of it? What men are poets who can speak of Jupiter if he were a man, but if he is an immense spinning sphere of methane and ammonia must be silent?
Science is a way to teach how something gets to be known, what is not known, to what extent things are known (for nothing is known absolutely), how to handle doubt and uncertainty, what the rules of evidence are, how to think about things so that judgments can be made, how to distinguish truth from fraud, and from show.
Of what good is our faith, our repentance, our baptism, and all the sacred ordinances of the gospel by which we have been made ready to receive the blessings of the Lord, if we fail, on our part, to keep the commandments.
Deep within every man there lies the dread of being alone in the world, forgotten by God, overlooked among the tremendous household of millions and millions.
Drunkenness does not create vice; it merely brings it into view.
My own being can be judged by the depths I reach in making these historical origins my own.
Punctuality is a quality the need of which is bound up with social co-operation. It has nothing to do with the relation of the soul to God, or with mystic insight, or with any of the matters with which the more elevated and spiritual moralists are concerned.
I believe in God, who made of one blood all nations that on earth do dwell. I believe that all men, black and brown and white, are brothers, varying through time and opportunity, in form and gift and feature, but differing in no essential particular, and alike in soul and the possibility of infinite development.
