Read the following passage to answer: 

Human beings have proved over a very long period of time that they are pugnacious in nature. They find in anything and everything, from an egg shell to a nation, a suitable cause of war. They are ready to use means and methods to champion the modalities of war, bloodshed and violence. Obviously, as science progressed with time, human beings were quick enough to use science for the purpose of war.

The greatest enemy of mankind is not science, but war. It is found that when science is used in a constructive way, it leads to undisturbed peace, but when science is perverted to destructive ends, it leads to unending war. Man uses science to make weapons to make war increasingly more terrible. Our main problem, therefore is not to curb science, but stop war. That is a job in which everybody must participate, including the scientists. The hour is late and our work has scarcely begun.
