What are the Conceptual Issues in the Definition of Technology?

Greek thinkers believe that technology learns from or imitates nature. For instance, house-building came about by imitating how spiders build their nets. In his philosophy of nature (physis), Aristotle held that technology or art imitates nature in some cases, and even (in other cases) completes what nature cannot bring to finish. However, Aristotle held that a fundamental ontological difference exists between natural and artificial entities. The unity of forms and matter, which makes up natural entities, is self-generating, while those of artificial entities are not they are generated by outward causes of human aims. that is, ‘natural products (animals and their parts, plants, and the four elements) move, grow, change, and reproduce themselves by inner final causes; they are driven by purpose of nature. Artifacts, on the other hand, cannot reproduce themselves’.For instance, there is no way a wooden bed can reproduce itself.
