Passage

What it means to “explain” something in science often comes down to the application of mathematics. Some thinkers hold that mathematics is a kind of language—a systematic contrivance of signs, the criteria for the authority of which are internal coherence, elegance, and depth. The application of such a highly artificial system to as other language does, to accurately describe the functioning of some aspect of the world.

At the center of the issue of scientific knowledge can thus be found questions about the relationship between language and what it refers to. A discussion about the role played by language in the pursuit of knowledge has been going on among linguists for several decades. The debate centers around whether language things is purely a matter of agreed-upon conventions, making knowledge tenuous, relative, and inexact.

Lately the latter theory has been gaining wider acceptance. According to linguists who support this theory, the way language is used varies depending upon changes in accepted practices and theories among those who work in a particular discipline. These linguists argue that, in the pursuit of knowledge, a statement is true only process in question, to be held as true until another, more compelling analogy takes its place.

In pursuing the implications of this theory, linguists have reached the point at which they must ask: If words or sentences do not correspond in an essential way to life or to our ideas about life, then just what are they capable of telling us about the world? In science and mathematics, acquisition of scientific knowledge? But this question has yet to be significantly addressed in the sciences.

Paragraph Purpose

Your task

Pin down exactly what the question asks about the passage — a detail, the author's view, the structure, or the main point — before looking at the choices.

Common trap

Answers that restate a true detail from the passage but don't answer the specific question being asked.

Winning move

Anticipate the answer in your own words from the passage, then find the choice that matches that prediction.

    Why this is right

    The fact that this focuses on side 2 of the debate among linguists should make us keep it on our first pass. The fact that it doesn't address the application of this thinking to math and science might give us pause but shouldn't be grounds for elimination because the transition into and out of P3 is all about the linguists. Ultimately, it ends up being the best answer we're given, even though it lacks a component from our prediction.

    P3 isn't about elaborating the differences between the two debated positions. It focuses exclusively on position 2.

    This answer gives us both the linguists and the scientists, and it calls back to the question posed in P1 about the nature of scientific explanation. That probably makes this one a keeper on the first pass. But there is a difference between applying a principle to a situation and demonstrating the similarity between two positions. P3 gives us clear application language and no explicitly comparative language: "Certainly this characterization would seem applicable to the sciences. In science...Under this view..." We're also never told that there is a current debate among scientists about the nature of explanation. If we research this callback to P1, we see an attribution: "Some thinkers hold..." While this often sets us up for a debate, we never actually get a second set of scientists that are debating this point of view. The only debate we're ever given is that of the linguists. Those two qualms are grounds to eliminate this very tempting trap answer.

  5. Wrong Point of View6% picked this

    explain the theory that mathematical statements are a kind

    The theory that math is a kind of language is expressed in P1. It's what some thinkers believe, and it forms the basis for the application of the linguists' position to the sciences in P3. But P3 isn't designed to explain this theory. It's primarily focused on the point of view of the 2nd camp of linguists: those who think the relationship between language and things is a matter of convention.
