cornell realism Flashcards
natural term features:
- Natural terms are able to be knowable a posteriori.
- They are able to be observed and tested.
- They are causally effacacious
terminological reduction meaning
expressing the meaning of one set of terms in terms of another set. It involves the clarification or analysis of concepts ie the correct definition
ontological reduction meaning
explaining properties or sets of things to the properties or sets of other things
If an action has the property of making us happy, it has the property of goodness
non-reductionist
a property may exist but that property cannot be understood in terms of any other property
what is the cornell realist stance on this?
non-reductionists through and through - both term and onto
- good is an irreducible property
- it is a sui generis property
- there are empirical reasons the property exists because they are naturalists but they cannot be reduced
what is the strategy cornell realists use?
they look at how scientific facts are understood and discovered and then apply it to the moral sphere
the theory of semantics cornell realists employ
causal regulation theory
what is causal regulation semantics
- Formal – “x is water iff x has the property that causally regulates our perception of the properties in the description of water”
- .the correct use of a term is regulated by the natural property that causes the things we percieve about it
-H2O - the natural thing - regulates our successful use of the term “water” through these discernable properties ie colour, taste, falls from sky etc
how is causal regulation semantics different to descriptivist understandings
- Descriptivism - water means the description “odourless, colourless, etc” and thats it - the stereotype/ description of water fixes the term “water”
- causal regulation semantics - water is the name for the molecular structure we pick out in the world that has certain stereotypical properties that are causally regulated by its molecular structure
-This differs from descriptive theories of meaning because it suggests that meaning isn’t just about matching descriptions or beliefs we associate with terms, but rather about what natural properties are actually causally regulating our successful use of those terms in practice. Even if early humans had very different beliefs about water than we do, they were still referring to H2O because that’s what was causally regulating their use of the term.
what other types of language might causal regulation semantics cover
- functional terms - knives, tools,
- ## theoretical terms - electrons, quarks, gravity
does functional language serve as a weakness of the theory or a strength showing its range
- it increases its utility as a theory - we dont need more explanations of the natural stuff - we have that from science but its interesting to include other groups and bridge the gap between natural language and theoretical/functional because it strengthens the gap between science and philosophy
- the theoretical language thats used in science is likened to the moral language used in philosophy - we can measure the effects of it and what might causally regulate it.
terms refer to what regulates their successful use, whether that’s through intrinsic structure or functional role.
descriptivism meaning
By using the description of the term, we can understand what the term is referring to - the extension of the term - we understand the term “apple” refers to a crunchy fruit that is green or red and high in vitamins.
Twin Earth thought experiment
There is an earth, and a twin earth. It looks identical to Earth. The one difference is that on twin earth, the thing we pick out to be water is not the molecular structure of H2O, it is XYZ. Oscar goes to Twin earth, and says ‘oh that water is lovely’ - is it referring to the same thing?
what is the point of the TEE?
Twin earth experiment -
- the point is to diffuse the idea that if two things have the same description, they must also have the same meaning.
- This idea works for functional things - knives are just things with a sharp edge; doesn’t matter about material, just has a role
- does not work for the TEE water or other natural kind terms
- Our intuitions suggest that meaning isnt to do w description, its to do with the property a name picks out
what do putnam and kripke believe?
(they are cornell realists)
- oscar and toscar are mistaken to think its the same thing
- picking out the property H20 on earth, XYZ on Twin earth
- when we talk about water we’re on about the property H20
- not in genuine disagreement because it is not the same thing
