Case Study from Physics: Galileo on Falling Bodies
摘要
The theory of explanation presented here needs to be illustrated with scientific examples so that its advantages and its shortcomings will be made clear. Galileo offered a hypothetical scenario on falling bodies which, even though is taken to be central to modern physics, it has never been considered as an explanation (at least in the field of philosophy of science). Galileo’s mingled representations—typically taken to be a “thought experiment” in the relevant literature—are therefore examined and presented anew here. It is shown that Galileo’s account can offer explanations under several contexts once its representational strategies are considered. The explanations it provides are compared with other competing theories, and mainly with Aristotle’sAristotle theory and a lexicographic ordering is offered in each case. Moreover, philosophical approaches that explicitly preclude the possibility of Galileo’s thought experiment to explain are addressed and it is argued that the opposite conclusion is to be drawn.
