What is Realism: Definition and 66 Discussions

Philosophical realism is usually not treated as a position of its own but as a stance towards other subject matters. Realism about a certain kind of thing (like numbers or morality) is the thesis that this kind of thing has mind-independent existence, i.e. that it is not just a mere appearance in the eye of the beholder. This includes a number of positions within epistemology and metaphysics which express that a given thing instead exists independently of knowledge, thought, or understanding. This can apply to items such as the physical world, the past and future, other minds, and the self, though may also apply less directly to things such as universals, mathematical truths, moral truths, and thought itself. However, realism may also include various positions which instead reject metaphysical treatments of reality entirely.Realism can also be a view about the properties of reality in general, holding that reality exists independent of the mind, as opposed to non-realist views (like some forms of skepticism and solipsism) which question the certainty of anything beyond one's own mind. Philosophers who profess realism often claim that truth consists in a correspondence between cognitive representations and reality.Realists tend to believe that whatever we believe now is only an approximation of reality but that the accuracy and fullness of understanding can be improved. In some contexts, realism is contrasted with idealism. Today it is more usually contrasted with anti-realism, for example in the philosophy of science.
The oldest use of the term "realism" appears in medieval scholastic interpretations and adaptations of ancient Greek philosophy.

    Local realism ruled out? (was: Photon entanglement and )

    Thank you for the suggestion. I should say this is the first thread I am starting since I joined physics forums four years ago. So this thread has branched from another one -"Photon entanglement and fair sampling assumption". I noted there that, on the one hand, so far no experiments...

    Debate Macroscopic Realism: Define or Disbelieve?

    In this thread I would like to start a debate on realism at the macroscopic level. To some of you this may be an issue that looks so trivial that it doesn't make any sense to try to talk about it. It is my hope that you still may be interested in making some comment, especially if someone else...

    Entanglement, causality and local realism

    I have been walking around with the notion that "quantum entanglement implies a sort causal relationship due to the states having a shared history". I am now not so sure that this is correct. When I talk about entanglement, I use the argument that the preparation of the entangled state...

    What is the basis for ethical realism and why is it important?

    Ethics are our theories on morals, and morals are what we should do. But why do we need ethics? The human being is a living organism, and we have to choose between life and death. Maintaining life depends on certain actions. It is the existence of life that gives rise to values, because it is...

    The Impact of Weak Realism on Bell's Theorem and Bohmian Interpretations

    Against "realism" Ok, no problem. That's not a problem, once I indeed favour a Bohmian interpretation. What he describes as naive (out of memory, once we start a new thread about it, I would have to reread it) is naive if taken as an axiom. EPR argue that this special situation...

    Is Morality a Kind of Science?

    Sam Harris, in The End of Faith, argues that morality is a kind of science. He says that “the fact that people of different times and cultures disagree about ethical questions should not trouble us. It suggests nothing at all about the status of moral truth.” He continues: Imagine what it...

    Is the Concept of a Self-Replicating Unmanned Spacecraft Feasible?

    I didn't know where to post this. It seems a bit week on science for the forums. I had this idea in for a role playing group I am in on myspace. Anyways the story is that I am in charge of the martian space navy and this is supposedly our newest weapon to use against the "space Nazis." It...

    Against Realism: Examining the Meaning of Local Realism

    "Against" Realism Travis Norsen has written an article entitled "Against Realism". In it, he argues that the phrase "local realism" is not meaningful. Against Realism (2006) Abstract: "We examine the prevalent use of the phrase “local realism” in the context of Bell’s Theorem and...

    Vampires, Evolution, and Realism

    I am going to attempt to write a story. Future humans have polluted the Earth far beyond repair, and they seek to create/alter humans (not sure yet) to survive in the harsh new climate. For some reason, a scientist is going to design the people like vampires (not sure why yet). Regardless, the...

    Material realism under attack

    How can the materialistic viewpoint be defended from the following attacks: 1) Local interactions vs. spooky action at a distance: Action at a distance suggests non-material interaction. 2) Descriptive laws vs. prescriptive laws: Prescriptive laws are non-material entities, and this is a...

    Moral Realism preferable to both Moral Absolutism and Moral Relativism

    The problem with the term ‘absolutism’ are the connotations of totalitarianism and non-revisability. Moral realism on the other hand, is the realism of scientific realism. What is real is what science says is real. Granted, what was once considered real no longer is, and what is considered...

    Mathematica Mathematical expression of Bell's local realism

    Mathematical expression of Bell's "local realism" I have started this thread to continue a discussion with NateTG that was starting to get a bit off-topic there. I will repeat the base comment and then reply to NateTG's last comment. I would invite anyone interested to please join in...

    Moral Observation Sentences: Can Ethics be Modeled on Science?

    Moral realism is the doctrine that there are true sentences that contain moral predicates that accurately describe the real world. Perhaps the strongest argument for investigating the possibility of moral realism is that the alternative is not pleasant to contemplate. Isn’t it true that it is...

    Local Realism After Bell: Can Quantum Mechanics and Local Realism Coexist?

    I will split this post so to make it easier to reply, if needed. I. Background ============= The EPR Paradox (1935) left the scientific community in a divided state. Some saw QM, even then a successful theory, as the likely victor in the debate over realism. But many remained unconvinced...

    The philosophy of Social Realism

    Do you think that the "ultimate reality of existence" will be related to or will have a social theme? By "reality" I mean in terms of the ultimate source of causation of the things we see today as reality. --------------------------------------------------------------------- I apologize...
