Perdurantism: Lewis I. Introduction Competing Intuitions 1. What matters is something in the neighbourhood of identity. (Intuition One), Thomson = I want to know that “I” an there 2. What matters is mental continuity and connectedness (Intuition Two) Connectedness: step Continuity: DEFINE FROM SLIDES (Person 1-7 are colour continuous, there is only a small variation in property to get from first to last, Seeming Tension between the Two Intuitions (1) If what matters is identity , it is a 1-1 relation, and doesn’t admit of degree they have to share all their features, you cannot be sort of identical (2) Mental Contunitty and Conndectedness isn’t 11 and does admit of degree there could be people in the future that are very similar/ continuous two people can be connected to you and can be causally dependant on me people can be more or less connected to someone ______________ (3) Either identity or MC/C isn’t what matters for survival Seeming Tension: Thomson’s Argument (4) Identity is what matters for survival ______ (5) MC/C Doesnt matter for survival Seeming Tension: Parfit’s Argument (4) MC/C is what matters for survival _______________ (5) Identity doesn’t matter for survival Overall - they choose which one is stronger, and reject one or another of the intuitive claims - Lewis says that you should not give up either theory, and wants to block this inference - he wants to say identity (or something in the neighbor of identity) and MC/C (or something in the neighbor of MC/C) can both be an issue II.Perdurantism (Four-Dimensionalism) - he wants to think that time is equally real, but they are in different spots - time you can think of as a fourth dimension that is extended outwards - contrasts with three-dimensionalism (all spacial dimensions), ten years ago and ten years in the future did/will happen, but they are not equally and real and they are not as real as here and now, no temporal extension

- four dimensionalists can say that because time is spread out and is all equally real, you are spread across all those times and you exist at all those times - you could say “right now I am here”, but that doesn’t make now more real than the past or the future - if you say “I am here”, and the back of the room isn’t any less real than the from of the room, you are just pointing out where you are situated in the timeline Emma - if you divide Emma in half, she is where her left half is, and also where her right half is - if you look at yourself, you are present where any of your limbs are - What aboue Emma at a later stage in life? - Just like Emma is present at her left and right half, she is present at the old stage and the new stage
