DIRECTIONS: Read the passage and answer the questions that follow.
Technology has been a subject of discussion in philosophy since the Greeks. The Greek philosopher Democritus, for example, believed that technology is an imitation of nature. House-building and weaving were first invented by imitating swallows and spiders building their nests and nets, respectively.
Aristotle held the same view that technology is the consequence of imitation of nature, but he added in his book Physics Book II that: "generally art in some cases completes what nature cannot bring to a finish."
Aristotle also distinguishes between natural things and artifacts. According to Aristotle, the former have their principles of generation and motion inside, whereas the latter, insofar as they are artifacts, are generated only by outward causes. For example, animals, which are natural things, can grow, move and reproduce. A wooden bed, which is an artifact made by a human, cannot move, grow, or reproduce itself.
Today, technology is a subject of debate because it is considered to be a double-edged sword. While it has helped humanity in extending its potential with outstanding inventions, it is nonetheless threatening humankind through some other destructive ones. In addition to polluting the earth in unprecedented ways, wars have become more and more devastating due to technological inventions. Ethical dimensions of recent technological developments, such as DNA engineering, have become a focal point of questioning and discussion. Philosophical debates have arisen over the use of technology, with disagreements over whether technology improves the human condition or worsens it.
To make matters worse, a consensus definition of technology has become more difficult to find due to recent evolution in science and its applications. It is especially confusing to decide whether technology refers to the machines (or more precisely the hardware), the rules that govern or make them work, the system that operates them or the different applications of science that are related to them. What is sure is that technology has shaped societies and adapted itself to people's changing needs.
Until recently, it was believed that the development of technology was restricted only to human beings, but 21st century scientific studies indicate that other primates and certain dolphin communities have developed simple tools and passed their knowledge to other generations.
