  • Fcaglp, Unlp, 2018
    Scientific Philosophy Gustavo E. Romero IAR-CONICET/UNLP, Argentina FCAGLP, UNLP, 2018 Epistemology Episteme, as distinguished from techne, is etymologically derived from the Ancient Greek word ἐπιστήμη for knowledge or science, which comes from the verb ἐπίσταμαι, "to know". In Plato's terminology episteme means knowledge, as in "justified true belief", in contrast to doxa, common belief or opinion. The word epistemology, meaning the study of knowledge, is derived from episteme. Plato Epistemology is the general study of cognitive processes and their outcome: knowledge. Knowledge is the product of cognitive operations made by an inquiring subject. It is not a thing or a substance, but a series of brain changes in the knower. Knowledge is not independent of the knowing subject, although we often feign it is for practical reasons. Knowledge is different from belief: I can know a story, for instance, but do not believe it. Belief implies a psychological adherence to some propositions. It is possible to believe something without understanding it, so belief is not necessary associated with neither truth nor justification. Knowledge acquisition requires a modification of the brain of the knower. This can be done in different ways, hence there are different kinds of knowledge. (i) Sensory-motor knowledge: the result of learning from actions. (ii) Perceptual knowledge: the result of perceiving events, either internal or external to the subject. (iii) Conceptual or propositional knowledge: the result of ideation, conjecturing, testing, correcting. Notice that not all knowledge is beneficial: we can learn trivialities, falsehoods, or highly harmful habits The three kind of knowledge are interrelated: conceptual knowledge can improve motor skills and perception; perception is used to evaluate conjectures; motor skills can help to improve perception and build instruments such as books, that enhance the ability to learn.

  • Sabine Hossenfelder on “The Case Against Beauty in Physics” Julia
    Rationally Speaking #211: Sabine Hossenfelder on “The case against beauty in physics” Julia: Welcome to Rationally Speaking, the podcast where we explore the borderlands between reason and nonsense. I'm your host, Julia Galef, and I'm here with today's guest, Sabine Hossenfelder. Sabine is a theoretical physicist, focusing on quantum gravity. She's a research fellow at the Frankfurt Institute for Advanced Studies, and blogs at Back Reaction. She just published the book, "Lost in Math: How Beauty Leads Physics Astray." "Lost in Math” argues that physicists, in at least certain sub-fields, evaluate theories based heavily on aesthetics, like is this theory beautiful? Instead of simply, what does the evidence suggest is true? The book is full of interviews Sabine did with top physicists, where she tries to ask them: what's the justification for this? Why should we expect beauty to be a good guide to truth? And, spoiler alert, ultimately, she comes away rather unsatisfied with the answers. So, we're going to talk about "Lost in Math" and the case for and against beauty in physics. Sabine, welcome to the show. Sabine: Hello. Julia: So, probably best to start with: what do you mean by beauty, in this context? And is it closer to a kind of “beauty is in the eye of the beholder” thing, like, every physicist has their own sort of aesthetic sense? Or is more like there's a consensus among physicists about what constitutes a beautiful theory? Sabine: Interestingly enough, there's mostly consensus about it. Let me put ahead that I will not try to tell anyone what beauty means, I am just trying to summarize what physicists seem to mean when they speak of beauty, when they say “that theory is beautiful.” There are several ingredients to this sense of beauty.

  • The Road to Afghanistan
    Introduction Hundreds of books—memoirs, histories, fiction, poetry, chronicles of military units, and journalistic essays—have been written about the Soviet war in Afghanistan. If the topic has not yet been entirely exhausted, it certainly has been very well documented. But what led up to the invasion? How was the decision to bring troops into Afghanistan made? What was the basis for the decision? Who opposed the intervention and who had the final word? And what kind of mystical country is this that lures, with an almost maniacal insistence, the most powerful world states into its snares? In the nineteenth and early twentieth century it was the British, in the 1980s it was the Soviet Union, and now America and its allies continue the legacy. Impoverished and incredibly backward Afghanistan, strange as it may seem, is not just a normal country. Due to its strategically important location in the center of Asia, the mountainous country has long been in the sights of more than its immediate neighbors. But woe to anyone who arrives there with weapon in hand, hoping for an easy gain—the barefoot and illiterate Afghans consistently bury the hopes of the strange foreign soldiers who arrive along with battalions of tanks and strategic bombers. To understand Afghanistan is to see into your own future. To comprehend what happened there, what happens there continually, is to avoid great tragedy. One of the critical moments in the modern history of Afghanistan is the period from April 27, 1978, when the “April Revolution” took place in Kabul and the leftist People’s Democratic Party seized control of the country, until December 27, 1979, when Soviet special forces, obeying their “international duty,” eliminated the ruling leader and installed 1 another leader of the same party in his place.

  • A Natural Introduction to Fine-Tuning
    A Natural Introduction to Fine-Tuning Julian De Vuyst ∗ Department of Physics & Astronomy, Ghent University, Krijgslaan, S9, 9000 Ghent, Belgium Abstract A well-known topic within the philosophy of physics is the problem of fine-tuning: the fact that the universal constants seem to take non-arbitrary values in order for live to thrive in our Universe. In this paper we will talk about this problem in general, giving some examples from physics. We will review some solutions like the design argument, logical probability, cosmological natural selection, etc. Moreover, we will also discuss why it's dangerous to uphold the Principle of Naturalness as a scientific principle. After going through this paper, the reader should have a general idea what this problem exactly entails whenever it is mentioned in other sources and we recommend the reader to think critically about these concepts. arXiv:2012.05617v1 [physics.hist-ph] 10 Dec 2020 ∗[email protected] 1 Contents 1 Introduction3 2 A Take on Constants3 2.I The Role of Units . .4 2.II Derived vs Fundamental Constants . .5 3 The Concept of Naturalness6 3.I Technical Naturalness . .6 3.I.a A Wilsonian Perspective . .6 3.I.b A Brief History . .8 3.II Numerical/General Naturalness . .9 4 The Fine-Tuning Problem9 5 Some Examples from Physics 10 5.I The Cosmological Constant Problem . 10 5.II The Flatness Problem . 11 5.III The Higgs Mass . 12 5.IV The Strong CP Problem . 13 6 Resolutions to Fine-Tuning 14 6.I We are here, full stop . 14 6.II Designed like Clockwork .

Philosophical reflections on modern quantum gravity research Keizo Matsubara Dissertation presented at Uppsala University to be publicly examined in Geijersalen, Building 6, (Eng 6-1023), English Park Campus, Thunbergsvägen 3P, Uppsala, Friday, January 18, 2013 at 10:15 for the degree of Doctor of Philosophy. The examination will be conducted in English. Abstract Matsubara, K. 2013. Stringed along or caught in a loop?: Philosophical reflections on modern quantum gravity research. Filosofiska Institutionen. 139 pp. Uppsala. ISBN 978-91-506-2324-6. A number of philosophical questions, all connected to modern research in quantum gravity, are discussed in this dissertation. The goal of research in quantum gravity is to find a quantum theory for gravitation; the ot- her fundamental forces are already understood in terms of quantum physics. Quantum gravity is studied within a number of different research programmes. The most popular are string theory and loop quantum gravity; besides these a number of other approaches are pursued. Due to the lack of empirical support, it is relevant to assess the scientific status of this rese- arch. This is done from four different points of view, namely the ones held by: logical positi- vists, Popper, Kuhn and Lakatos. It is then argued that research in quantum gravity may be considered scientific, conditional on scientists being open with the tentative and speculative nature of their pursuits. Given the lack of empirical progress, in all approaches to quantum gravity, a pluralistic strategy is advised. In string theory there are different theoretical formulations, or dualities, which are physi- cally equivalent.
