The purpose of this study is to gain a better understanding of the role of abstraction and idealization in Galileo’s scientific inquiries into the law of free falling motion, and their importance in the history of science. Because there is no consensus on the use of the terms “abstraction” and “idealization” in the literature, it is necessary to distinguish between them at the outset. This paper will argue for the importance of abstraction and idealization in physics and the theories and (...) laws of physics constructed with abduction from observations and that these theoretical laws of physics should be tested with deduction and induction thorough quasi-idealized entities rather than empirical results in the everyday world. Galileo’s work is linked to thought experiments in natural science. Galileo, using thought experiments based on idealization, persuaded others that what had been proven true for a ball on an inclined plane would be equally true for a ball falling through a vacuum.

The objective of our study is to explore scientific creativity with a focus on intellectual (thinking) skills in the cognitive aspect by analyzing scientific theories, which are basically the creativity of historical great scientists, Galileo, Newton, Einstein While our study laid stress on the cognitive domain, exploration of the creativity of great scientists is also connected with affective characteristics (motives, task commitment, etc.) and their environmental factors (incubation period). Great scientists of the science history were aware of the discrepancy issue (...) among different fields of study and long searched for solutions, which they held in their minds. As a result, they created a certain hypothesis using the abstraction strategy in which they leave only the considerations suitable for the world view of the time. Then, they conducted a thought experiment that justified it. The reason why it was difficult for general people to understand was that there was a domain transition beyond materials obtained in the abstraction process. Furthermore, they all had strong motives for the future as well as task commitment. Knowledge is a product of natural selection, and the fusion of knowledge that does not presuppose the unity of knowledge is meaningless. (shrink)

William Gilbert’s 1600 book, De magnete, greatly influenced early modern natural philosophy. The book describes an impressive array of physical experiments, but it also advances a metaphysical view at odds with the soon to emerge mechanical philosophy. That view was animism. I distinguish two kinds of animism – Aristotelian and Platonic – and argue that Gilbert was an Aristotelian animist. Taking Robert Boyle as an example, I then show that early modern arguments against animism were often effective only against Platonic (...) animism. In fact, unacknowledged traces of Aristotelian animism can be found in Boyle’s mechanical account of nature. This was Gilbert’s legacy. (shrink)
