Personal Horizon
In his book ''Dream, Death and the Self'', J. J. Valberg develops the concept of the personal horizon. He attempts to bring out his subject-matter by considering the dream hypothesis – what if ''this'' were a dream? In Valberg's view, an undetermined horizon would necessarily be internalised (a.k.a. subconscious) if ''this'' were all a dream. This leads to "horizonal" conceptions of consciousness, mind, experience, life, the self, etc. Valberg subsequently considers death, and argues that when the meaning of death strikes us in the right way, it presents us with the prospect of nothingness – not there being nothing ''for me'', but nothing ''period''. This corresponds to one's personal horizon being the ''pre-eminent'' one, corresponding to a weak version of solipsism (arguably closely related to Hare's egocentric presentism). Valberg points out the difficulty of reconciling this with his commitment to the view that he shares the world with metaphysical equals; he continues by re ...

Dream Hypothesis
The simulation theory is the hypothesis that reality could be simulated—for example by quantum computer simulation—to a degree indistinguishable from "true" reality. It could contain conscious minds that may or may not know that they live inside a simulation. This is quite different from the current, technologically achievable concept of virtual reality, which is easily distinguished from the experience of actuality. Simulated reality, by contrast, would be hard or impossible to separate from "true" reality. There has been much debate over this topic, ranging from philosophical discourse to practical applications in computing. Arguments Simulation argument A version of the simulation hypothesis was first theorized as a part of a philosophical argument on the part of René Descartes, and later by Hans Moravec. The philosopher Nick Bostrom developed an expanded argument examining the probability of our reality being a simulation. His argument states that at least one of t ...

Solipsism
Solipsism (; ) is the philosophical idea that only one's mind is sure to exist. As an epistemological position, solipsism holds that knowledge of anything outside one's own mind is unsure; the external world and other minds cannot be known and might not exist outside the mind. Varieties There are varying degrees of solipsism that parallel the varying degrees of skepticism: Metaphysical Metaphysical solipsism is a variety of solipsism. Based on a philosophy of subjective idealism, metaphysical solipsists maintain that the self is the only existing reality and that all other realities, including the external world and other persons, are representations of that self, and have no independent existence. There are several versions of metaphysical solipsism, such as Caspar Hare's egocentric presentism (or perspectival realism), in which other people are conscious, but their experiences are simply not ''present''. Epistemological Epistemological solipsism is the variety of ideali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egocentric Presentism
Egocentric presentism is a form of solipsism introduced by Caspar Hare in which other persons can be conscious, but their experiences are simply not . Similarly, in related work, Hare argues for a theory of perspectival realism in which other perspectives do exist, but the present perspective has a defining intrinsic property. In one example that Hare uses to illustrate his theory (starting on page 354 of the official version of his paper), you learn that you are one of two people, named A and B, who have just been in a train crash; and that A is about to have incredibly painful surgery. You cannot remember your name. Naturally, you hope to be B! The point of the example is that you know everything relevant that there is to know about the objective world; all that is missing is position in it, that is, whose experiences are , A's or B's. This example is easily handled by egocentric presentism because under this theory, the case where the present experiences are A's is fundamentall ...

Subjectivism
Subjectivism is the doctrine that "our own mental activity is the only unquestionable fact of our experience", instead of shared or communal, and that there is no external or objective truth. The success of this position is historically attributed to Descartes and his methodic doubt, although he used it as an epistemological tool to prove the opposite (an objective world of facts independent of one's own knowledge, ergo the "Father of Modern Philosophy" inasmuch as his views underlie a scientific worldview). Subjectivism accords primacy to subjective experience as fundamental of all measure and law. In extreme forms like Solipsism, it may hold that the nature and existence of every object depends solely on someone's subjective awareness of it. One may consider the qualified empiricism of George Berkeley in this context, given his reliance on God as the prime mover of human perception. Metaphysical subjectivism Subjectivism is a label used to denote the philosophical tenet that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centered World
A centered world, according to David Kellogg Lewis, consists of (1) a possible world, (2) an agent in that world, and (3) a time in that world. The concept of centered worlds has epistemic as well as metaphysical uses; for the latter, the three components of a centered world have connections to theories such as actualism, solipsism (especially egocentric presentism and perspectival realism In Caspar Hare's theory of perspectival realism, there is a defining ''intrinsic'' property that the things that are in perceptual awareness have. Consider seeing object A but not object B. Of course, we can say that the visual experience of A i ...), and presentism, respectively.

Vertiginous Question
Benj Hellie's vertiginous question is as follows: of all the subjects of experience out there, why is ''this'' one—the one corresponding to the human being referred to as Benj Hellie—the one whose experiences are ''live''? (The reader is supposed to substitute their own case for Hellie's.) A simple response to this question is that it reduces to "Why are Hellie's experiences live from Hellie's perspective," which is trivial to answer. However, Hellie argues, through a parable, that this response leaves something out. The parable describes two situations, one reflecting a broad global ''constellation'' view of the world and everyone's phenomenal features, and one describing an ''embedded'' view from the perspective of a single subject. The former seems to align better with the simple response above, but the latter seems a better description of consciousness. David Chalmers has written a response to Hellie, but he did not address the question itself. Hellie's argument is also clos ...

Epistemological Theories
Epistemology (; ), or the theory of knowledge, is the branch of philosophy concerned with knowledge. Epistemology is considered a major subfield of philosophy, along with other major subfields such as ethics, logic, and metaphysics. Epistemologists study the nature, origin, and scope of knowledge, epistemic justification, the rationality of belief, and various related issues. Debates in epistemology are generally clustered around four core areas: # The philosophical analysis of the nature of knowledge and the conditions required for a belief to constitute knowledge, such as truth and justification # Potential sources of knowledge and justified belief, such as perception, reason, memory, and testimony # The structure of a body of knowledge or justified belief, including whether all justified beliefs must be derived from justified foundational beliefs or whether justification requires only a coherent set of beliefs # Philosophical skepticism, which questions the possibili ...

Metaphysics Of Mind
Metaphysics is the branch of philosophy that studies the fundamental nature of reality, the first principles of being, identity and change, space and time, causality, necessity, and possibility. It includes questions about the nature of consciousness and the relationship between mind and matter, between substance and attribute, and between potentiality and actuality. The word "metaphysics" comes from two Greek words that, together, literally mean "after or behind or among he study ofthe natural". It has been suggested that the term might have been coined by a first century CE editor who assembled various small selections of Aristotle's works into the treatise we now know by the name ''Metaphysics'' (μετὰ τὰ φυσικά, ''meta ta physika'', 'after the ''Physics'' ', another of Aristotle's works). Metaphysics studies questions related to what it is for something to exist and what types of existence there are. Metaphysics seeks to answer, in an abstract and ful ...
