Philosophy 201 For Victims Of RiskasPrevious:
Frege, Sense, and Reference (Part 1)So to understand how predicates have a sense and reference like singular terms do, it might help if I can quickly summarize Frege’s idea of what a sentence is supposed to accomplish.
Frege thought a word only has referent in the context of a complete sentence, that is when the referent is assigned. Sentences themselves also have a sense too, but this sense can only be understood when all the words that make up a complete sentence contribute their sense and referents. That is to say, words are the building blocks for sentences and it is only when all contributions of the words are systematically given, can we get the sense and ultimately the reference of a complete sentence.
What is the reference for a completed sentence? Its truth value. If the sentence is successful in representing the world as it is, it gives us an accurate picture of reality. A reality that exist independently of our minds and a reality that is fundamentally available to us. A sentence relates to its truth value ( being true or false) in the same way a name relates to the object it picks out.
So what does a predicate contribute to a sentence? What could a referent be for a predicate like things like being red, wicked, bald, or a widow? The first answer is usually say that the referent is some kind of concept or idea. Frege might have been okay with that at first, but he’d want more precision so he borrowed the mathematical idea of a function. In the way the square root function takes a number and gives us its square root, the predicate function is similar, it takes the object and relates it someway to the world that contributes to getting the result if a complete sentence is true or false.
Important Concepts From FregeSense and Reference: These are two aspects of meaning for words. Sense helps us understand a word by providing a path to the reference. The reference is the object out in the world that the word is picking out.
Sentences: A complete sentence is made up of words that all contribute to the sentences own sense and reference. When we grasp/understand a sentence, we understand the conditions that will make a sentence either true or false, the referent determines the truth value of that sentence.
Context Principle: The only unit with meaning is that of a complete sentence, which was systematically built up by all the terms that compose it. When you understand all the rules governing individual terms, derivation of truth conditions becomes possible and then the reference is understood and a truth value is assigned.
So Wut?This is a very useful understanding of language, because it gives us a possible way of explaining something Linguists like Noam Chomsky have argued for at length; we understand sentences we’ve never heard before, and there is no limit to the number of sentences we could create. How is this possible given our brains are finite and limited?
Possible maybe because an infinite number of sentences can be built from a finite vocabulary by way of repeated application of rules (sort of like the successor rule in Set Theory, for you math/engineering/comp sci geeks out there) of structure (syntax) and by individual terms contributing various senses, references, and meaning by a separate set of rules (semantics).
The bare bones laid out help support the basic notion that one of language’s primary functions (if not its most important one) is helping us express and communicate what is true about the world.
Relating It To RiskasSo this account of Frege probably strikes most people as intuitive. While I’m sure most people probably remain unconvinced about the details of singular terms and predicates working in particular ways, but I’m willing that most people agree with the idea truth is the most important goal of language establishing a relation between our words and our world.
Of course the word truth is just stuffed with all sorts of metaphysical baggage we’ll need to unpack, but I want to point out that where Riskas ends up is a radical rejection of Frege. To Riskas, he is just another metaphysical realist who suffers from ‘cackling’ incoherence just like the theists he scorns.
I think Riskas’ use of the term ‘incoherence’ is a classic bait n switch. Popularizations of Nietzsche do the same thing with the slogan “God is Dead!” but when you track down the parable where this phrase comes from and understand its context, the sentiments are not all that radical. So when reading Fence Sitter and Kerry Shirts’ reactions to Riskas’ book and then looking into it myself, I feel I saw the bait and switch taking place.
For example, when Darth J gives his hilarious descriptions of basic Mormon beliefs about a primate God with a celestial harem out there in a distance place in the universe around a star named Kolob, what is he doing?
On a Frege analysis, we could say that he is exposing the truth conditions of Mormon sentences, showing everyone just what it would take for these beliefs to be true. Casting it as such, it immediately becomes clear that the possibility of such sentences being true is abysmally low. Or look at Fence Sitter trying to untangle the idea of eternal families, by pointing out contradictions between beliefs, impossibilities, and a lack of cohesion in Mormon beliefs, he is doing something similar, pointing out the truth conditions of Mormon sentences.
For Frege, incoherent would be someone communicating in a language that was alien to you. You didn’t understand the rules governing syntax and semantics, so you are completely unable to determine the truth conditions of sentences. So pointing out how little the probability of Mormon beliefs being true is, or outright claiming they are false would commit one to saying Mormon beliefs are coherent in the sense just described.
But for Frege this was all about language and logic with assumptions about what truth was, it is mostly metaphysical. Riskas rejects this metaphysical approach and adopts by way of Rorty and Kai Nielsen a epistemological approach to truth, but before we can really explore that, we have much more to cover.
Next philosopher is Bertrand Russell.
