It is not easy to see how the more extreme forms of nationalism can long survive when men have seen the Earth in its true perspective as a single small globe against the stars.
Interpretation
Extreme nationalism may diminish as humanity gains a broader perspective of the Earth as a small part of the universe.
Arthur C. Clarke's quote suggests that when people recognize the Earth as a tiny, interconnected part of a vast universe, it becomes harder to hold onto extreme nationalist views. This realization fosters a sense of shared humanity and encourages global unity over divisive national identities.
In practice
In a speech about global cooperation, this quote serves to highlight the importance of seeing ourselves as part of a larger community.
Nowhere in space will we rest our eyes upon the familiar shapes of trees and plants, or any of the animals that share our world. Whatsoever life we meet will be as strange and alien as the nightmare creatures of the ocean abyss, or of the insect empire whose horrors are normally hidden from us by their microscopic scale.
As our own species is in the process of proving, one cannot have superior science and inferior morals. The combination is unstable and self-destroying.
It has yet to be proven that intelligence has any survival value.
The best measure of a man's honesty isn't his income tax return. It's the zero adjust on his bathroom scale.
It was the mark of a barbarian to destroy something one could not understand.
My favorite definition of an intellectual: 'Someone who has been educated beyond his/her intelligence'.
[death]...the abyss from where no traveler is permitted to return
Memory offers up its gifts only when jogged by something in the present. It isn't a storehouse of fixed images and words, but a dynamic associative network in the brain that is never quiet and is subject to revision each time we retrieve an old picture or old words.
Show a people as one thing, only one thing, over and over again, and that is what they become.
Our deeds determine us, as much as we determine our deeds.
Because there is a law such as gravity, the Universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the Universe exists, why we exist. It is not necessary to invoke God to light the blue touch paper and set the Universe going.
Indifference, to me, is the epitome of evil.
