So the universe is not quite as you thought it was. You'd better rearrange your beliefs, then. Because you certainly can't rearrange the universe.
Interpretation
Our understanding of the universe may be flawed, and it is our beliefs that need to be adjusted rather than reality itself.
Isaac Asimov highlights the idea that the universe operates independently of our perceptions and beliefs. When faced with new information or insights, it is essential for individuals to reassess and modify their beliefs accordingly, as the universe will not change to fit our misconceptions. This quote invites deep reflection on the importance of adapting our understanding to align with the actual nature of reality.
In practice
In a discussion about scientific discoveries that challenge popular beliefs.
Democracy cannot survive overpopulation. Human dignity cannot survive it. Convenience and decency cannot survive it. As you put more and more people into the world, the value of life not only declines, but it disappears. It doesn't matter if someone dies.

During the century after Newton, it was still possible for a man of unusual attainments to master all fields of scientific knowledge. But by 1800, this had become entirely impracticable.
I am sorry to say that there is too much point to the wisecrack that life is extinct on other planets because their scientists were more advanced than ours.
In a society under the forms of which the stronger faction can readily unite and oppress the weaker, anarchy may as truly be said to reign as in a state of nature.
This appetite to choose death by pleasure if it is available to choose - this appetite of your people unable to choose appetites, this is the death.
The more I think about myself, the more I'm persuaded that, as a person, I really don't exist. That is one of the reasons why I can't believe in any orthodox religion: I cannot believe in my own soul. No, I am a chemical compound, conditioned by environment and education. My "character" is simply a repertoire of acquired tricks, my conversation a repertoire of adaptations and echoes, my "feelings" are dictated by purely physical, external stimuli.
Puritanism, believing itself quick with the seed of religious liberty, laid, without knowing it, the egg of democracy.
Metaphysics is a restaurant where they give you a thirty thousand page menu, and no food.
