“The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.”
I think what Isaac Asimov tries to say with this quote is how science is always a step in front of ethics and moral reasoning. We have all this technology, but we still have to figure out if it is morally acceptable to make use of it or a ethical way of using it. For example, stem cells are a great resource but the ethical way of getting them is not on the same level as how much it is needed.
Also, how some people make use of the technology (science) in an unethical way, i.e. atomic weapons.
The thing is that people, having different opinions and thoughts on what is “good” and “bad”, make the process of scientific progress slower. Scientist can, mostly, agree on a scientific theory or on scientific knowledge; but when non-scientists (“normal people”? whatever) want to make use of the scientific knowledge acquired it takes time and a lot of discussion about whether it is “right” or “wrong”.
