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.
When I was growing up reading history books as a young student, it seemed all wars had a winner. Yet in today's wars, it is increasingly clear that no one wins. Everyone loses.
God loves the saints as the purchase of his Son's blood. They cost him dear, and that which is so hardly got shall not be easily lost. He that was willing to expend his Son's blood to gain them, will not deny his power to keep them.

Though I still turn up my coat-collar in a lonely way and am always looking at myself in mirrors, theyβre only habits and give no clue at all to my character, whatever that is. The most difficult performance in the world is acting naturally isnβt it? Everything else is artful.
Your whole life is a message. Every act is an act of self-definition . Everything you think, say and do sends a message about you.
A lie preserved in stained glass doesn't make it more true.
