Question

I have recently noticed a curious phenomenon with the word any, in that it sometimes does not behave like the universal quantifier every. Consider this pair of sentences: John can outrun every man on the sports team and John can outrun any man on the sports team. In this particular case, the word any functions as a universal quantifier, and so the sentences mean the same thing. However, now consider this pair of sentences: John cannot outrun every man on the sports team and John cannot outrun any man on the sports team. Those two sentences do not mean the same thing. So, my real question is, are there papers that do a logical analysis of the word any? I would be very interested in such texts. If you are asking a question about how 'every' and 'any' work in the English language, and the differences between them, thenthis articlehas some useful information. They tend to differ when negated, or when used in a conditional, or when embedded in another expression, or when used in a question. E.g. contrast: I do not own any book written by Schopenhauer.

I do not own every book written by Schopenhauer.

If any person here is from New Zealand, that would be surprising.
If every person here is from New Zealand, that would be surprising.

This piano is too heavy for any man here to lift.
This piano is too heavy for every man here to lift.

Is any book in this library by a Greek author?
Is every book in this library by a Greek author? Another difference is that 'any' can be used with mass nouns, but 'every' cannot. Is there any water? makes sense, but Is there every water? does not. For added confusion, 'each' is different again, and is not always identical with 'every'. If you asking about how these terms differ when rendering them into formal logic, then there are some subtleties to observe. 'Any' usually suggests an arbitrary item, and can be ambiguous. 'Every' indicates an entire class of things. 'Each' may differ from 'every'. For example, there is a difference between asserting that F(n) holds foreachnatural number n, and asserting that (∀x)F(x) holds, which would naturally be read as that F(x) holds foreveryx. The difference is to be found inthe ω-rule. a. Investigate academic databases like JSTOR or PhilPapers using keywords related to the logical analysis of any.
b. Explore scholarly articles on the semantic differences between every and any within formal logic and linguistic studies.
c. Consider philosophical texts focusing on semantics, logic, or philosophy of language for insights into distinctions between these terms.
d. Explore linguistic studies or papers discussing the nuanced uses of any and every in various contexts to understand their logical implications.

Answer 1

In English, 'every', 'any', and 'each' have different meanings and implications, especially when used in statements with negation or logical conditions. The verb agreement with indefinite pronouns changes based on whether they take a singular or plural form, and gender-neutral language is encouraged for inclusivity. Studying formal logic and grammatical constructions can illuminate the complex functions of these words.

Step-by-step explanation:

The use of indefinite pronouns such as 'every', 'any', and 'each' can influence the meaning of a sentence, especially when negation is involved or in various syntactic constructions. While 'every' often refers to all members of a group collectively, 'any' might imply just one out of a group or any part of a quantity. This impacts how sentences are understood, particularly when the context involves logic or philosophical statements. For instance, the logical implications of 'John cannot outrun every man on the sports team' differ from 'John cannot outrun any man on the sports team', with the first implying that there is at least one man John cannot outrun, while the latter suggests John cannot outrun any members at all.

When investigating these semantic nuances, it's helpful to look at how different indefinite pronouns agree with verbs depending on their singular or plural context. For instance, 'anyone', 'everyone', and 'something' take a singular verb, while 'both', 'few', and 'several' require a plural verb. Additionally, the pronouns 'all', 'any', 'none', and 'some' can take either singular or plural verbs based on what they refer to. For example, 'Most of the class has formalized proposals' versus 'Most of the students have formalized proposals'.

It is also essential to be aware of gender-neutral language usage, especially when pairing pronouns with indefinite pronouns to avoid gender bias. The sentence 'Everybody has their own opinion' is now more acceptable due to its inclusivity than 'Everybody has his own opinion'.

To fully understand the logical and grammatical functions of these words, one may need to delve into topics such as formal logic, universal statements, conditional statements, and how they translate into natural language.
