Best order to read David Lewis?

Is David Lewis an Eternalist?

Lewis’s commitment to four-dimensionalism was a result of his endorsement of two theses: (1) unrestricted composition, and (2) eternalism. Unrestricted composition is the thesis that any objects compose some object.

Is David Lewis a Physicalist?

But I am still a physicalist in good standing. For I believe that every concrete thing, living or non-living, is exhaustively composed of particles, and that its intrinsic state at any moment is completely specified by specifying the state—the physical state—of this system of particles.

What is Lewis account of propositions?

The standard view is that propositions are (or at least determine) sets of possible worlds, and that the content of a belief is a proposition. To believe something then is to locate yourself within a class of possible worlds; to believe that you inhabit one of the worlds at which the proposition is true.

Is David Lewis a functionalist?

Summary. David Lewis’s position, often called analytic functionalism, was inspired by Ryle’s analytic behaviorism, which took psychological predicates to express complex sets of behavioral dispositions.

What is genuine modal realism?

Modal realism is the view propounded by David Kellogg Lewis that all possible worlds are real in the same way as is the actual world: they are “of a kind with this world of ours.” It is based on the following tenets: possible worlds exist; possible worlds are not different in kind from the actual world; possible worlds

How does David Lewis define time travel?

Time travel is commonly defined with David Lewis’ definition: An object time travels if and only if the difference between its departure and arrival times as measured in the surrounding world does not equal the duration of the journey undergone by the object.

Who is the father of logic?


As the father of western logic, Aristotle was the first to develop a formal system for reasoning.

What are the 3 types of propositions in argumentation?

There are three types of proposition: fact, value and policy.

Are propositions metaphysical?

The Metaphysics of Propositions

These include being the information conveyed by an utterance of a sentence, being the primary bearers of truth and falsity, being the possessors of modal properties like being possible and necessary, and being the things we assume, believe, and doubt.

What is humean Supervenience?

Humean supervenience is the conjunction of three theses: Truth supervenes on being, Anti-haecceitism, and Spatiotemporalism. The first clause is a core part of Lewis’s metaphysics.

What does modal mean philosophy?

A modal is an expression (like ‘necessarily’ or ‘possibly’) that is used to qualify the truth of a judgement. Modal logic is, strictly speaking, the study of the deductive behavior of the expressions ‘it is necessary that’ and ‘it is possible that’.

What is Actualism in literature?

Actualism is the philosophical position that everything there is — everything that can in any sense be said to be — exists, or is actual. Put another way, actualism denies that there is any kind of being beyond actual existence; to be is to exist, and to exist is to be actual.

Is time travel possible Stephen Hawking?

According to Stephen Hawking, time travel is possible, and not just in the way we might think. Backward time travel is not supported by Hawking’s theories, because new matter (a new you) would need to be created – one existing in the past and one in the present, traveling back in time.

Is time travel metaphysically possible?

It is widely accepted that this is metaphysically possible. In some stories, time travellers can change the past. Many philosophers have explained how that, too, is metaphysically possible.

Is backwards time travel possible?

There are known to be solutions to the equations of general relativity that describe spacetimes which contain closed timelike curves, such as Gödel spacetime, but the physical plausibility of these solutions is uncertain. Many in the scientific community believe that backward time travel is highly unlikely.

Does the past still exist?

In short, space-time would contain the entire history of reality, with each past, present or future event occupying a clearly determined place in it, from the very beginning and for ever. The past would therefore still exist, just as the future already exists, but somewhere other than where we are now present.

Do wormholes exist?

Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They’ve never been seen, but according to Einstein’s general theory of relativity, they might exist.

Has anyone traveled to the future?

Although many people are fascinated by the idea of changing the past or seeing the future before it’s due, no person has ever demonstrated the kind of back-and-forth time travel seen in science fiction, or proposed a method of sending a person through significant periods of time that wouldn’t destroy them on the way.

Has a time machine been invented?

In fact, a time machine has already been built. Scientists, however, are still working on how to make it as efficient as possible, like in the Back to the Future movies.

Is it possible to go back in time and change the past?

The idea is that backwards time travel is impossible because if it occurred, time travellers would attempt to do things such as kill their younger selves (or their grandfathers etc.). We know that doing these things—indeed, changing the past in any way—is impossible.
