In my opinion, main responsibility is given to the system of this society whether it is capitalist or socialist, and not to individuals and small groups. Individuals in society are nothing but a gear in watch. If you have a complaint on the system of this society, then you must find a way to change the system. It may not be, I think, an appeal to individuals. Materialists have studied the way to change the system since the class struggle existed. You can find another way which may be very different from yours in the writings of materialists from atomists to Marxists Of course, there have been movements of scientists to reach to the peace of the world. They were mainly lead by socialist and communist scientists. You can also get books on these history in Korea. In addition, if you see the book, 'Making atomic bomb' (translated in Korean), you may understand the thoughts of scientists (Einstein, Bohr, Heisenberg, Oppenheimer, Zilard(?), etc. Bohr thought the a-bomb must not be made through the 'Hyup-Sang'(<-- this is my ignorance) of USA, GRB, and USSR and he even suggested that idea to the head of powers.). Scientists are also human beings. They think as others. They are nothing but common peoples.
