[A]ll knowledge is one. When a light brightens and illuminates a corner of a room, it adds to the general illumination of the entire room. Over and over again, scientific discoveries have provided answers to problems that had no apparent connection with the phenomena that gave rise to the discovery.
Interpretation
Knowledge is interconnected and contributes to a greater understanding of the world.
In this quote, Isaac Asimov emphasizes the idea that all knowledge is interlinked; when we gain insights in one area, it enhances our understanding across various fields. He illustrates this through the metaphor of light, suggesting that discoveries in science not only solve specific problems but also illuminate unrelated areas of knowledge, leading to a deeper and more comprehensive grasp of reality.
In practice
During a lecture on scientific methodology, one could use this quote to illustrate the value of interdisciplinary research.
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.
Science does not promise absolute truth, nor does it consider that such a thing necessarily exists. Science does not even promise that everything in the Universe is amenable to the scientific process.
Democracy cannot survive overpopulation.
Although the time of death is approaching me, I am not afraid of dying and going to Hell or (what would be considerably worse) going to the popularized version of Heaven. I expect death to be nothingness and, for removing me from all possible fears of death, I am thankful to atheism.
A subtle thought that is in error may yet give rise to fruitful inquiry that can establish truths of great value.
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.
Science is history arranged according to the superstition and taste of the moment. The vocabulary of scholars has no wit, no salt. These heavy tomes have no soul, they are filled with distress.
On the ordinary view of each species having been independently created, we gain no scientific explanation.
As in biomedical science, pioneering industrial inventions have not been mothered by necessity. Rather, inventions for which there was no commercial use only later became the commercial airplanes, xerography and lasers on which modern society depends.
I think that the discovery of antimatter was perhaps the biggest jump of all the big jumps in physics in our century.
These slender little people (Homo Habilis), the size of modern 12 year olds, were devoid of fangs and claws and almost certainly slower on foot than the four legged animals around them. They could have succeeded in their new way of life only by relying on tools and sophisticated cooperative behavior
