 In focusing on technology as a practice sustained by engineers, similar to the way philosophy of science focuses on the practice of science as sustained by scientists, analytic philosophy of technology could be thought to amount to the philosophy of engineering. Indeed many of the issues related to design, discussed below in Sections  2.3  and  2.4,  could be singled out as forming the subject matter of the philosophy of engineering. The metaphysical issues discussed in Section  2.5  could not, however, and analytic philosophy of technology is therefore significantly broader than philosophy of engineering. The very title of Philosophy of Technology and Engineering Sciences (Meijers 2009), an extensive up-to-date overview, which contains contributions to all of the topics treated in the next section, expresses the view that technology and engineering do not coincide. Which is not to say, however, that the book offers a clear conception of what makes technology different from engineering, or more than engineering. In fact, the existence of humanities philosophy of technology and analytic philosophy of technology next to each other reflects a basic ambiguity in the notion of technology that the philosophical work that has been going on has not succeeded in clarifying.
