Chomsky, however, has claimed that we can go one step better. He points out that a theory that also accounts for how children acquire their language is the best. He calls this an explanatorily adequate grammar. The simple theory of parameters might get this label. Generative grammar strives towards explanatorily adequate grammars.

8. THE SCIENTIFIC METHOD AND THE STRUCTURE OF THIS TEXTBOOK
Throughout this chapter I’ve emphasized the importance of the scientific method to the study of syntax. It’s worth noting that we’re not only going to apply this principle to small problems or specific rules, but we’ll also apply it in a more global way. This principle is in part a guide to the way in which the rest of this book is structured.
In chapters 2–5 (the remainder of Part 1 of the book) we’re going to develop an initial hypothesis about the way in which syntactic rules are formed. These are the phrase structure rules (PSRs). Chapters 2 and 3 examine the words these rules use, the form of the rules, and the structures they generate. Chapters 4 and 5 look at ways we can detail the structure of the trees formed by the PSRs.
In chapters 6–9 (Part 2 of the book), we examine some data that present problems for the simple grammar presented in Part 1. When faced withmore complicated data, we revise our hypotheses, and this is precisely what we do. We develop a special refined kind of PSR known as an X-bar rule. X-bar rules are still phrase structure rules, but they offer a more sophisticated way of looking at trees. This more sophisticated version also needs an additional constraint known as the “theta criterion”, which is the focus of chapter 8.
In chapters 10–13 (Part 3) we consider even more data, and refine our hypothesis once again, this time adding a new rule type: the transformation (we retain X-bar, but enrich it with transformations). Part 4 of the book (chapters 14–18) refines these proposals even further.
With each step we build upon our initial hypothesis, just as the scientific method tells us to. I’ve been teaching with this proposal–then-revision method of theory construction for a couple of years now, and every now and then I hear the complaint from a student that we should just start with the final answer (i.e. the revised hypotheses found in the later chapters in the book). Why bother learning all this “other” “wrong” stuff? Why should we bother learning phrase structure rules? Why don’t we just jump straight into X-bar theory? Well, in principle, I could have constructed a book like that, but then you, the student, wouldn’t understand why things are the way they are in the latter chapters. The theory would appear to be unmotivated, and you wouldn’t understand what the technology actually does. By proposing a simple hypothesis early on in the initial chapters, and then refining and revising it, building new ideas onto old ones, you not only get an understanding of the motivations for and inner workings of our theoretical premises, but you get practice in working like a real linguist. Professional linguists, like all scientists, work from a set of simple hypotheses and revise them in light of predictions made by the hypotheses. The earlier versions of the theory aren’t “wrong” so much as they need refinement and revision. These early versions represent the foundations out of which the rest of the theory has been built. This is simply how science works.
9. CONCLUSION
In this chapter, we’ve done very little syntax but talked a lot about the assumptions underlying the approach we’re going to take to the study of sentence structure. The basic approach to syntax that we’ll be using here is generative grammar; we’ve seen that this approach is scientific in that it uses the scientific method. It is descriptive and rule-based. Further, it assumes that a certain amount of grammar is built in and the rest is acquired.
IDEAS, RULES, AND CONSTRAINTS INTRODUCED IN THIS CHAPTER
1 Linguistics: The scientific study of language.
2 Syntax (the field): The scientific study of sentence structure
3 Syntax (as part of grammar): The level of linguistic organization that mediates between sounds and meaning, where words are organized into phrases and sentences.
4 The Scientific Method: Observe some data, make generalizations about that data, draw a hypothesis, test the hypothesis against more data.
5 Falsifiable Prediction: To prove that a hypothesis is correct you have to look for the data that would prove it wrong. The prediction that might prove a hypothesis wrong is said to be falsifiable.
6 Grammar: Not what you learned in school. This is the set of mental rules or procedures that generate a sentence.
7 Prescriptive Grammar: The grammar rules as taught by so-called “language experts”. These rules, often inaccurate descriptively, prescribe how people should talk/write, rather than describe what they actually do.
8 Descriptive Grammar: A scientific grammar that describes, rather than prescribes, how people talk/write.
9 Anaphor: A word that ends in -self or -selves (a better definition will be given in chapter 5).
10 Antecedent: The noun an anaphor refers to.
11 Asterisk (*): The mark used to mark syntactically ill-formed (unacceptable or ungrammatical) sentences. The hash mark, pound, or number sign (#) is used to mark semantically strange, but syntactically well-formed, sentences.
12 Grammatical Gender: Masculine vs. Feminine vs. Neuter. Does not have to be identical to the actual sex or gender identity of the referent. For example, a dog might be female, but we can refer to it with the neuter pronoun it. Similarly, boats don’t have a sex, but are grammatically feminine.
13 Number: The quantity of individuals or things described by a noun. English distinguishes singular (e.g., a cat) from plural (e.g., cats). Other languages have more or less complicated number systems.
14 Person: The perspective of the participants in the conversation. The speaker or speakers (I, me, we, us) are called the first person. The addressee(s) (you) is called the second person. Anyone else (those not involved in the conversation) (he, him, she, her, it, they, them) is referred to as the third person.
15 Case: The form a noun takes depending upon its position in the sentence. We discuss this more in chapter 11.
16 Nominative: The form of a noun in subject position (I, you, he, she, it, we, they).
17 Accusative: The form of a noun in object position (me, you, him, her, it, us, them).
18 Corpus (pl. Corpora): A collection of real-world language data.
19 Native Speaker Judgments (Intuitions): Information about the subconscious knowledge of a language. This information is tapped by means of the acceptability judgment task.
20 Semantic Judgment: A judgment about the meaning of a sentence, often relying on our knowledge of the context in which the sentence was uttered.
21 Syntactic Judgment: A judgment about the form or structure of a sentence.
22 Garden Path Sentence: A sentence with a strong ambiguity in structure that makes it hard to understand.
23 Center Embedding: A sentence in which a relative clause
