Since the dawn of human ingenuity, people have devised ever more cunning tools to cope with work that is dangerous, boring, burdensome, or just plain nasty. That compulsion has resulted in robotics—the science of conferring various human capabilities on machines. And if scientists have yet to create the mechanical version of science fiction, they have begun to come close.
As a result, the modern world is increasingly populated by intelligent gizmos whose presence we barely notice but whose universal existence has removed much human labor. Our factories hum to the rhythm of robot assembly arms. Our banking is done at automated teller terminals that thank us with mechanical politeness for the transaction. Our subway trains are controlled by tireless robo-drivers. And thanks to the continual miniaturization of electronics and micro-mechanics, there are already robot systems that can perform some kinds of brain and bone surgery with submillimeter accuracy—far grea

B. the wide use of machines in manufacturing industry
C. the invention of tools for difficult and dangerous work

D. respond independently to a changing world
Human societies have experienced so many wars, but have you ever thought about what a war really is War may be a natural expression of biological instincts and drives toward aggression in the human species. Natural impulses of anger hostility and territoriality are expressed through acts of violence. These are all qualities that humans share with animals. Aggression is a kind of innate survival mechanism or an instinct for self-preservation that allows animals to defend themselves from threats to their existence. But on the other hand human violence shows evidence of being a learned behavior. In the case of human aggression violence cannot be simply reduced to an instinct. The many expressions of human violence are always conditioned by social conventions that give shape to aggressive behavior. In human societies violence has a social function. It is a strategy for creating or destroying forms of social order. Religions have taken a leading role in directing the powers of violenc
