  1. Principle Theory or Constructive Theory?Robert W. P. Luk - manuscript
    Einstein made a distinction between principle theories like Newtonian mechanics and constructive theories like kinetic theory of gases. Are these two distinct types of theories fundamentally different from each other or can they be regarded to belong to just one type of theory? We explore this issue with respect to the theory of scientific study and come to the conclusion that there is only one type of (scientific) theory, and the constructive theory is a principle theory with only one principle, (...)

  • What Do We Mean by “True” in Scientific Realism?Robert W. P. Luk - 2020 - Foundations of Science 25 (3):845-856.
    A crucial aspect of scientific realism is what do we mean by true. In Luk’s theory and model of scientific study, a theory can be believed to be “true” but a model is only accurate. Therefore, what do we mean by a “true” theory in scientific realism? Here, we focus on exploring the notion of truth by some thought experiments and we come up with the idea that truth is related to what we mean by the same. This has repercussion (...)

  • Why is Bayesian confirmation theory rarely practiced.Robert W. P. Luk - 2019 - Science and Philosophy 7 (1):3-20.
    Bayesian confirmation theory is a leading theory to decide the confirmation/refutation of a hypothesis based on probability calculus. While it may be much discussed in philosophy of science, is it actually practiced in terms of hypothesis testing by scientists? Since the assignment of some of the probabilities in the theory is open to debate and the risk of making the wrong decision is unknown, many scientists do not use the theory in hypothesis testing. Instead, they use alternative statistical tests that (...)

  • Sketching a Theology based on Historical Science.Robert W. P. Luk - 2022 - Science and Philosophy 10 (1):21-44.
    St. Thomas Aquinas envisaged theology to be a kind of scientia which was considered as a kind of first cause science. However, science of that time is different from “modern” science. Recently, a theory of scientific study is developed, which outlines science by a theory and some models similar to knowledge in physics. According to this theory, sciences organize their knowledge consisting of theories, models and experiments interacting with physical situations. Perhaps, it is possible to organize knowledge of Christian theology (...)

  • Insights in How Computer Science can be a Science.Robert W. P. Luk - 2020 - Science and Philosophy 8 (2):17-46.
    Recently, information retrieval is shown to be a science by mapping information retrieval scientific study to scientific study abstracted from physics. The exercise was rather tedious and lengthy. Instead of dealing with the nitty gritty, this paper looks at the insights into how computer science can be made into a science by using that methodology. That is by mapping computer science scientific study to the scientific study abstracted from physics. To show the mapping between computer science and physics, we need (...)

  • To Explain or to Predict: Which One is Mandatory?Robert W. P. Luk - 2018 - Foundations of Science 23 (2):411-414.
    Recently, Luk mentioned that scientific knowledge both explains and predicts. Do these two functions of scientific knowledge have equal significance, or is one of the two functions more important than the other? This commentary explains why prediction may be mandatory but explanation may be only desirable and optional.
