This sounds interesting. As a bit of constructive criticism, please put some examples high up.

You tell me it does cool things. Great, show me. I've looked about on the various pages and can see only one example and I don't understand it:

    text.md:0:10: wallace.uncomparables Comparison of an uncomparable: 'unique' can not be compared.

What's the context of this, what's the error it would have caught in my writing?

The tool is in a perfect place to show this off as it's text.

[suchow]

Good idea. If you run `proselint` without specifying a document, it'll run on the demo text, which you can also access here: https://gist.github.com/suchow/c7856f21128aee89ad55. Also, there's a live demo available at: http://proselint.com/write. It's been tested only on the latest version of Chrome, and I doubt it will handle the load here, but give it a try.

[Vivtek]

This would catch something like "even more unique". In fact, looking at the code (https://github.com/amperser/proselint/blob/master/proselint/...) it would even catch something like "extremely unique", which I've been guilty of using.

But yes, there should be examples on the front page.

[joosters]

So this program is like having some insufferable pedants arguing over your language? Great!

Does it accept 'nearly unique' ?

[debacle]

It accepts "kind of unique" and "hardly unique" but also "greatly unique" which in my mind is very close to "very unique."

This tool is a blunt instrument. Writing is an art.

[johnny4000]

What exactly is the argument or implication in the last two sentences? There are many works of art that use "blunt" instruments. Say the Venus of Willendorf or a Serra sculpture, though that depends on what you mean by blunt. Even in literature blunt tools are use such as a pencil.

[conceit]

So, I think english is an "analytical language", although I wouldn't know what it means, it inspires me to assume, that by analyszing the sentence you can make out that extremely could refer to something else than the uniqueness, isn't it? EG the phrase could mean, something was unique because of one of any number of extremes, unique by extremity. Sure, that should be uniquely extreme, but what I said shows something else. If there are different qualities that could be unique, wouldn't it make sense to quantify that? Of course, if a logic is so weak it cannot have the peano axioms, you cannot advance beyond uniqueness. (What about missing all-quantor in propositional logic and uniqueness in predicate logic? I'm just stabbing in the dark, really.)

One cannot have gradations of uniqueness

[conceit]

Imagine an object that is unique in exactly one respect, and another in two. Obviously, the other has more uniqueness. Now, if a the first has precisely only the one characteristic of having not really any characteristic at all, then that's a totally different degree of uniqueness. So either is more unique in a specific respect. But Arguably, the nothingness is most unique, if not the only really unique thing. So if we can ignore that, because no one in his right mind would talk about nothing, we can most of always readily conclude, that the first type of a collection of unique'ish things is concerned.

Is this regression ad absurdum or argumentum ad silencium?

[SixSigma]

I like your thinking.

The link I posted really concerns the insufferability of someone who corrects technicalities of language rather than a discussion on whether uniqueness is a countable property.

[shawabawa3]

Some people feel you should never ever say things like "more unique", "most unique" etc

Which I think is equally as misguided as trying to force "data" to be plural, and that "less than 3" is wrong

[ScottBurson]

> Some people feel you should never ever say things like "more unique", "most unique" etc

I am among them. Here's why:

(1) There are already other words that express related concepts that are subject to gradation: "rare", "special", "unusual", and "extraordinary" come to mind.

(2) The original meaning of "unique", namely "one of a kind", is an important concept. If we let the word's meaning get lost, we will not be able to express that meaning as easily.

[amelius]

In a mathematical context, something is either "unique" or it is not. There is no in-between state.

But you can easily define it to mean something else. And you can even make "uniqueness" comparable.

[x1798DE]

I think it's obvious that what people mean is that "more unique" = "unique in more dimensions" or "the degree to which this differs from the norm is greater".

E.g. (2, 4, 7) (2, 4, 8) (2, 8, 4) (2, 4, 7) (1, 4, 8) (0, 9, 3) (987, 4, 7)

When asked what are the "most unique" sets in that list, you'd probably be acting deliberately obtuse if you chose anything but one of the last two.

[reikonomusha]

I guess it's understandable but why not choose an appropriate word like "different" and keep "unique" a very strong word?

[x1798DE]

Well, you don't really get a choice. I'm just describing how the word is used, not suggesting an alternate meaning for it.

[ajuc]

Math has long tradition of generalizing definitions to make sense for larger domains, when it's useful. See fractional powers, complex numbers, quaternions, and many more.

I can imagine defining uniqueness as a function returning real number from <0; 1> instead of a boolean value. For example:

    let U(p, x, X) be the uniqueness of property(function) p(x) for element x of set X 

    U(p, x, X) = 1.0 - (size of X')/(size of X\{x}), where
    X' = set of all elements x' of X such that p(x')=p(x) and x' != x

Property p of element x of set X is strictly unique when, and only when U(p, x, X) = 1

When it's useful? For example for speaking about minimizing collisions of hashes for given data.

Another way of thinking about it: uniqueness is 1-probability of uniformly randomly finding element with same value of p in X as x after removing x from X.

[stared]

In a mathematical world you operate with abstract objects. In the real word - you need to abstract things; before that everything is unique; after that - well, depends on your abstraction. So unless you talk about mathematics, things can be more or less unique.

[MawNicker]

This is a excellent and subtle comment. You seem like someone with a tolerance for philosophical nit-picking. Please forgive me if I'm mistaken.

Instead of saying everything is unique we could simply say that there is nothing. A thing is itself an abstraction. The concrete world is without inherently distinct things. We must abstract things for "unique" to describe something at all. As you implied, this process is arbitrary. Every way in which you could abstract things implies a distinct notion of "uniqueness". To simply select one "uniqueness" (like mathematics) is arbitrary. But to consider every possible "uniqueness" equally is also arbitrary. Without prioritizing forms of "uniqueness" we can only construct a partially ordered set. So when you void a fixation on mathematics, things can be more, less or "incomparably" unique.

I suspect most pairs of things are incomparably unique. Further, I suspect most binary qualities are predominantly incomparable. I don't know that you should never say things like "more unique" but it might be fair to issue a warning in a prose linter. Any binary quality used as a continuum requires an arbitrary combination of it's distinct forms. If this isn't specified then it only has meaning for those who already know what it is.

[mbrock]

Some philosophers, thinking especially of Graham Harman, have started reacting against the now sort of commonplace idea that "there are no things (or objects) in reality."

From a common sense perspective, it's obvious that there are things. Sure, you can point out the flux and decay of all entities, but still, this table here is a coherent thing even if it's made from parts in a temporary arrangement.

In some sense, philosophy itself is destroyed when you go down the path of denying objects, since philosophy crucially deals with concepts, and concepts are "thought objects."

Harman describes two modes of denying objects: undermining and overmining. Undermining is the tendency to say "really, this object is just a composition of these other particles," while overmining is the tendency to say "this object is just a modulation in a grand monistic entity."

Instead of that, he recommends an ontology of objects that's pretty interesting and fun to read about. He would, I think, agree that objects are unique in that they are (in programmer jargon) "pointer equal" to only themselves... and each real object, for that reason, has an infinity of potential that's never exhausted by any "arbitrary" perception of it... yet still, we perceive other objects not directly, but through aesthetic caricatures, and on that level you might have different degrees of uniqueness.

[MawNicker]

Thank you very much for this comment. I'm an armchair philosopher and I hadn't heard of Graham Harman. His notion of objects is beautiful. In one motion nihilism both compels me to accept my sins and deprives me of any path to salvation. Harman's objects capture the essential impetus of nihilism without ultimately voiding conception. In fact, they even capture the paradox of nihilism. The denial of objects necessarily implies an objective system: dualism. First there is an object contriving infinitely varied "caricature objects". Then there must be another object that is (infinitely) not any of those. This expression of our relationship to The Great Unknowable Reality is much saner. It doesn't overmine. It doesn't undermine. It doesn't leave me oscillating between affirmation and denial. Also, most importantly, I'm given a clue to further knowledge. I am that contriving object. This is just a caricature of reality. My participation in it's consideration is entirely arbitrary. I'm haunted by the concern that knowledge exists which cannot be captured by this freedom. But for now these objects certainly get us further than nothing. ;)

[ajuc]

If world is a set - everything is unique by definition.

You need to define some relation on that set to get classes of abstraction. And that's exactly what abstraction means :)

[vram22]

Even math has an infinity of infinities - Cantor findings etc.

[nimish]

It's a good thing then that most people don't use it in its technical sense

An easy fix for this not problem is to use distinct instead of unique

[Jedd]

Curiously (but perhaps only to me) all things are comparable - able to be compared.

If you mean similar, may I commend the word similar? ;-)

[mbrock]

It's a linter, it's going to have some kind of "false positives." Maybe you could put an annotation that tells the linter you're sure that you mean it.

Semi-off-topic, but the notion of "more unique" reminds me of Sapolsky's TED talk about humans as the "uniquiest" animal.
