Identity Of Indiscernibles

AbstractIt is argued that from a genuine Leibnizian point of view the well-known thought experiment, call it BTE, involving a possible world with only two exactly similar objects, cannot be used to refute Leibniz’s principle of the identity of indiscernibles (LIdI). If the claim that there are two objects in BTE is based on primitive thisnesses, the Leibnizian objection is that there are no such things; and even if there were, then, quite generally, something true of one object – that it has

The principle of Identity of Indiscernibles has been challenged with various thought experiments involving symmetric universes. In this paper, I describe a fractal universe and argue that, while it is not a symmetric universe in the classical sense, under the assumption of a relational theory of space it nonetheless contains a set of objects indiscernible by pure properties alone. I then argue that the argument against the principle from this new thought experiment resists better than those from classical symmetric universes three main objections put forth against this kind of arguments.

The Way

Leibniz said that space and time are well-founded phenomena. Few readers can make much literal sense out of this idea, so I shall describe a small possible world in which it is true. I do not contend that Leibniz had my construction in mind, but I do follow Leibnizian guidelines. The first trick is to reverse the maxim that every monad mirrors the world from its own point of view. Points of view, and hence a space of points, can be constructed from a non-relational account of the perceptions of each monad. But we cannot fabricate space alone. We must build up laws of nature simultaneously. We must also employ a measure of the simplicity of the laws of nature. Moreover we require that, in a literal sense, the perception of each monad is a sum of its Petits perceptions. The identity of indiscernibles, in its application to space, is an automatic consequence of this construction. Although I shall examine only one possible world, there is a general recipe for such constructions, in which none of the above elements can be omitted. This is a striking illustration of the way in which the many different facets of Leibniz's metaphysics are necessarily inter-connected.

The paper considers the analogy of theoretical modeling and thought experiment in economics. The authors provide historical and epistemological analysis of thought experiments and their relations to the material experiments in natural science. They conclude that thought experiments as instruments are used both in physics and in economics, but in radically different ways. In the natural science, a thought experiment is tightly connected to the material experimentation, while in economics it is used in isolation. Material experiments serve as a means to demonstrate the reality, while thought experiments cannot be a full-fledged instrument of studying the reality. Rather, they constitute the instrument of structuring the field of inquiry.

Fake Barn

Abstract Studies in experimental philosophy claim to document intuition variation. Some studies focus on demographic group-variation; Colaço et al., for example, claim that age generates intuition variation regarding knowledge attribution in a fake-barn scenario. Other studies claim to show intuition variation when comparing the intuition of philosophers to that of non-philosophers. The main focus has been on documenting intuition variation rather than uncovering what underlying factor(s) may prompt such a phenomenon. We explore a number of suggested explanatory hypotheses put forth by Colaço et al., as well as an attempt to test Sosa's claim that intuition variance is a result of people ‘filling in the details’ of a thought experiment differently from one another. We show (i) that people respond consistently across conditions aimed at ‘filling in the details’ of thought experiments, (ii) that risk attitude does not seem relevant to knowledge ascription, (iii) that people's knowledge ascriptions do not vary due to views about defeasibility of knowledge. Yet, (iv) we find no grounds to reject that a large proportion of people appear to adhere to so-called subjectivism about knowledge, which may explain why they generally have intuitions about the fake-barn scenario that vary from those of philosophers.

Theological Thought

Religious notions have long played a role in epistemology. Theological thought experiments, in particular, have been effective in a wide range of situations in the sciences. Some of these are merely picturesque, others have been heuristically important, and still others, as I will argue, have played a role that could be called essential. I will illustrate the difference between heuristic and essential with two examples. One of these stems from the Newton–Leibniz debate over the nature of space and time; the other is a thought experiment of my own constructed with the aim of making a case for a more liberal view of evidence in mathematics.

This paper intends to discuss some aspects of what we conceive as personal identity: what it consists in, as well as its alleged fragility. First I will try to justify the methodology used in this paper, that is, the use of allegories in ontological debates, especialy in the form of thought experiments and science fiction movies. Then I will introduce an original thought experiment I call “Who am I actually?,” one that was coined with the intent to shed light on several aspects of the issue under examination, that is, the fragility of personal identity. Then I will move on to Christopher Nolan’s film The Prestige, as well as to Derek Parfit’s ‘divided minds’ thought experiment, to further discuss the fragility of personal identity; next to identity theft, the prospect of duplication is also intriguing, especially with regard to the psychological impact this might have on both the prototype and the duplicate. I will conclude with the view that spatial and temporal proximity or coexistence, especially when paired with awareness on behalf of the duplicates, would expectedly result in the infringement of the psychological continuity of one’s identity.

Insight Into

Thought experiments are performed in the imagination. We set up some situation, we observe what happens, then we try to draw appropriate conclusions. In this way, thought experiments resemble real experiments, except that they are experiments in the mind. The terms “thought experiment,” “imaginary experiment,” and “Gedankenexperiment” are used interchangeably. There is no consensus on a definition, but there is widespread agreement on which are standard examples. It is also widely agreed that they play a central role in a number of fields, especially physics and philosophy. There are several important questions about thought experiments that naturally arise, including what kinds of thought experiments there are, what roles they play, and how, if at all, they work. This last question has been the focus of much of the literature: How can we learn something new about the world just by thinking? Answers range from “We don’t really learn anything new” to “We have some sort of a priori insight into how nature works.” In between there are a great variety of rival alternative accounts. There is still no consensus; debate is wide open on almost every question pertaining to thought experiments.

I've always thought that Leibniz's monadology offers comfort during parallel session conferences. Assuring us that each monad reflects the whole, although from its particular point of view, Leibniz makes the sanguine case that one can make sense of things even if one's viewpoint is sadly singular. In the mad rush from one paper session to the next, knowing that at best one gets to hear a third of what is being said, it helps to invoke a bit of Leibnizian optimism. And indeed, Dublin seemed like a best possible world during the three days of the Defining Space conference taking place in October 2007. Generously hosted and meticulously organised, the University College Dublin-led event succeeded not only in attracting more than eighty papers that contributed to elucidate the concept of space in relation to architecture, art, and the city, but also in creating an atmosphere of conviviality and intellectual generosity which gave the event an unusual sense of sharing.
