The Ship of Theseus September 2016 Presentation by Peggy Verrall Heraclitus roughly 6 century BCE Plato Plato 5th-4th Plutarch Questions. If Theseus takes his ship in for repair each time he docks, then sails with one or more new parts, is he still sailing the Ship of Theseus ? However, if it is preserved, like the Victory, after his death, with every conceivable part being replaced over time, and possibly more than once and by different people, is it still The Ship of Theseus? One possible solution is to hold to what is known as The Mereological Theory of Identity Hereinafter called MTI Where does this leave us? In only one of our stated scenarios does The Ship of Theseus have all parts identical with the original. MTI too severe. How about Spatio/Temporal Continuity. Hereinafter known as STI To summarize: Theseus sets sail on his ship, Ship A He arrives on his ship, which we can now call ship B because it has had all its parts replaced. According to STC this is The Ship of Theseus. Then along comes Ship C, the reconstituted one. MTI allows this to be the original. But neither allows for diassembly and reassembly of an object. What do we mean by Identity? What is Identity? One’s physical body ? One’s mind ? • So what about people who • What is the mind? have replacement legs? • Is it separate from the • Arms? brain? • Hearts? • Is it separable from the • Damaged but unreplaced body? bodies? • Is there something which • Unusable bodies? (Stephen Hawking) common sense tells us is • What about the scifi there, even if it is difficult to favourite – just a brain-? describe exactly? Would that mean my identity is also an illusion? What about yours? ? Books read and/or consulted. Thought experiment On the Power and Limit of Imaginary Cases Tamar Szabo Gendler 2000 The Outer Limits of Reason Noson S.

This work Functionalist and essentialist positions could be affected by attempts to model empirical data from a behavioral study on these parameters differently. Participants initially performed paradox resolution with different modeling techniques: a Conceptual Tendency Test (CTT) in which they were discriminant analysis (DA), decision tree analysis and asked to rate a set of propositions which are directly related neural networks. While each method has its own advantages to the core concept of “sameness/identity” involved in the and disadvantages, this paper attempts to compare and to paradox before answering the paradox (see method). contrast these methods trying to select the best model for In this current work, we focus on two main research future work.

Plato uses the image of a winding labyrinth as a metaphor for the process of philosophical investigation in his dial ogue Euthydemus. His image expresses his belief that, unlike the arts of rhetoric or sophistry —which rely on mere assertion and counter- assertion—philosophy absolutely requires that we retrace our steps in an argument and constantly re-examine our views in order to arrive at knowledge of the true and good. This is what we as students of philosophy aim to do, and this journal is meant to aid in that process. our purpose This journal was created with a threefold purpose. First, to provide undergraduate students with the experience and opportunity of publishing a paper in a philosophical journal. Secondly, to give an opportuity for students to be involved in peer to peer interaction through the process of creating the journal.

Personal Identity I. Persona
Philosophy 110W: Introduction to Philosophy Hamilton College Spring 2012 Russell Marcus Class #11 - Personal Identity I. Personal Identity In philosophy, we look for true answers to difficult questions. The evidence for our answers may be difficult to establish. Our answers remain debatable. Sometimes, we decide that the questions are poorly formed, as Wittgenstein says about the skeptical question. We are starting a unit on personal identity. The questions we are pursuing concern the nature of our selves. Who are we? What makes us the same people that we were when we were young? What makes us the same as we grow older? Is there a core set of properties that are consistent over our lives? Is there even something called the self, or are we just a bundle of properties, with no unifying thing? Haecceity: thisness II. Material Constitution and the Body Theory One answer to the question of in what our identity consists, one that would be consistent with our general, contemporary preference for materialism, is that we are identical with our bodies. We can call this the body theory of personal identity. The problem with the body theory is that our bodies are changing constantly. We lose skin and hair all the time; most dust is just dead skin and hair. Every seven years, all the cells in our bodies are replaced. If we identify ourselves with our bodies, we are not the same person we were, say, a moment ago. (And, my son is made out of chicken nuggets and noodles.) The problems with the body theory underlie the debtor’s paradox.

Composition, Persistence and Identity 1
DRAFT COPY This is a penultimate draft. The final, published version (also with less typos!) appears in in The Routledge Companion to Metaphysics ed. Le Poidevin, Simons, McGonigal and Cameron (2009): 296-309. Please cite that version. Composition, Persistence and Identity 1. Material Objects Unlike many other metaphysical categories, whether there are material objects is (Idealism aside) uncontroversial. No wonder then that the metaphysics of material objects has become a febrile area of contemporary philosophy as everyone (philosopher and non-philosopher alike) can make sense of, and have an interest in, the issues that are at stake. Three areas are mainly discussed: composition, persistence and identity (not that material objects are the sole subjects of these areas, nor do these areas exhaust the metaphysics of material objects). This chapter concentrates on how these areas help us answer questions about what material objects there are, and specifically examines the relationship, the consanguinity, between these areas. 2. Composition 2.1 The Special Composition Question My hand is a part of me; a star is composed of hydrogen and helium; conjoined twins overlap. These are mereological facts i.e. concerning the relation of wholes to their parts: my hand is related to me by parthood; a large number of hydrogen and helium atoms stand in the composition relation to the star; the two twins stand in the overlapping relation to one another. These mereological relations have been formalised in temporally relativised mereology. Take as primitive the relation of temporally relativised proper parthood: ‘__ is a proper part of __ at time __’. Next we can define some mereological vocabulary.

Paradoxes of Personal Identity: Teletransportation, Split Brains, and Immaterial Souls Phil 20229: Midterm Exam Study Guide
Paradoxes of personal identity: teletransportation, split brains, and immaterial souls phil 20229: Midterm exam study guide Jeff Speaks In class, Thursday, February 25 On the midterm, you will be given four questions from the following list, and will have to answer three: 1. Explain Zeno’s Racetrack and Achilles arguments for the conclusion that motion is impos- sible. What do these arguments assume about the nature of space and time? Is it possible to complete an infinite number of tasks in a finite time? Why or why not? 2. Explain Zeno’s Stadium argument. What does the argument attempt to show? Is it successful? Why or why not? 3. Explain what the A-series properties are, and why McTaggart thought that they were contradictory. Is his argument successful? Why or why not? What, if anything, does it show us about the nature of time? 4. Kant provided arguments against the two claims that material things are ultimately com- posed of simples, and that all material things are composite. Explain the argument which you think is less convincing, and say how you think it can be resisted. 5. Explain why the combination of Galilean relativity, the principle of relativity, and the speed of light’s being a law of nature is inconsistent. What was Einstein’s response to this paradox, and why does it involve the relativity of simultaneity? Why does the relativity of simultaneity lead to the phenomenon of time dilation? 6. Explain the Doomsday Paradox, and say what you think the best response to the paradox is. 7. Explain the paradox of the statue and the clay, and say what you think the best response to the paradox is.

Neurath's Boat, Theseus' Ship and Chisholm's Nonintactly Persisting Universe ABSTRACT
1 Neurath’s Boat, Theseus’ Ship and Chisholm’s Nonintactly Persisting Universe ABSTRACT: Neurath’s famous boat metaphor paints a picture of a coherentist system of knowledge where every statement (protocol or otherwise) is always open to revision. However, his total rejection of correspondence theory, I argue, raises questions about what “statements” actually are, since they can no longer be defined with reference to an external world. I believe that, if Neurath’s coherentism is taken seriously, statements must be ontological entities that make up a universe that is a nonintactly persisting object, in Roderick Chisolm’s sense. I explain this concept with recourse to the classic metaphysical riddle of the ship of Theseus. Otto Neurath famously compared our experience of the world to our being on a ship at sea that never reaches land. Instead, we have to constantly make repairs on the open water. His point was that we don’t have the benefit of being able to stop and check our theories of the world from a detached perspective. There are no absolute, indubitable certainties to which our theories must conform. We must be prepared to revise anything and everything as necessary, in order to maintain the coherence of our world system—to stay afloat: “We are like sailors who must rebuild their ship on the open sea, never able to dismantle it in dry-dock and to reconstruct it there out of the best materials” (Neurath 1932/33, 201). Neurath’s metaphor is reminiscent of the ancient metaphysical riddle of Theseus’ ship: if the parts of a ship are slowly replaced over time, until the ship has none of its original parts, would it still be the same ship? In what follows, I use Roderick Chisholm’s language to suggest that, if Neurath’s metaphor is accurate, our world is a nonintactly persisting object, dropping and gaining parts over time according to the pragmatic needs of coherence.

List of Paradoxes 1 List of Paradoxes
List of paradoxes 1 List of paradoxes This is a list of paradoxes, grouped thematically. The grouping is approximate: Paradoxes may fit into more than one category. Because of varying definitions of the term paradox, some of the following are not considered to be paradoxes by everyone. This list collects only those instances that have been termed paradox by at least one source and which have their own article. Although considered paradoxes, some of these are based on fallacious reasoning, or incomplete/faulty analysis. Logic • Barbershop paradox: The supposition that if one of two simultaneous assumptions leads to a contradiction, the other assumption is also disproved leads to paradoxical consequences. • What the Tortoise Said to Achilles "Whatever Logic is good enough to tell me is worth writing down...," also known as Carroll's paradox, not to be confused with the physical paradox of the same name. • Crocodile Dilemma: If a crocodile steals a child and promises its return if the father can correctly guess what the crocodile will do, how should the crocodile respond in the case that the father guesses that the child will not be returned? • Catch-22 (logic): In need of something which can only be had by not being in need of it. • Drinker paradox: In any pub there is a customer such that, if he or she drinks, everybody in the pub drinks. • Paradox of entailment: Inconsistent premises always make an argument valid. • Horse paradox: All horses are the same color. • Lottery paradox: There is one winning ticket in a large lottery. It is reasonable to believe of a particular lottery ticket that it is not the winning ticket, since the probability that it is the winner is so very small, but it is not reasonable to believe that no lottery ticket will win.
