In logic, syntax is anything having to do with formal languages or formal systems without regard to any interpretation or meaning given to them. Syntax is concerned with the rules used for constructing, or transforming the symbols and words of a language, as contrasted with the semantics of a language which is concerned with its meaning.
Carnap himself soon renounced his definitions of logicality, and in his Introduction to Semantics (1942: 247), he says that the most important change to Logical Syntax “concerns the distinction between logical and descriptive signs, and the related distinction between logical and factual truth”.
According to Carnap, logical syntax is a formal theory sets forth the rules for the construction of sentences, their transformation into other sentences. The analysis. structure of these rules is termed the method of logical and is said to be the only correct method of philosophy. Sentences are divided into object-sentences and. sentences.

Logic. It is one of the oldest intellectual disciplines in human history. It has been studied through the centuries, by Gottfried Leibniz, George Boole, Charles Babbage and Lady Lovelace, Russell and Whitehead, and others. And it is still a subject of active investigation today. We use Logic in just about everything we do. We use it in our professi...
For many, Logic is an esoteric subject. It is used primarily by mathematicians in proving complicated theorems in geometry or number theory. It is all about writing formal proofs to be published in scholarly papers that have little to do with everyday life. Nothing could be further from the truth. Consider the interpersonal relations of a small gro...
Once we know which world is correct, we can find that some sentences must be true even though they are not mentioned in the premises we are given. For example, in the first world we saw above, everybody likes somebody even though we are not told that fact explicitly. Unfortunately, things are not always so simple. Although logical sentences can som...
One way to check whether a set of sentences logically entails a conclusion is to examine the set of all worlds in which the given sentences are true. Unfortunately, determining logical entailment by checking all possible worlds is impractical in general. There are usually many, many possible worlds. Moreover, in some cases the number of possible wo...
So far, we have illustrated everything with sentences in English. While natural language works well in many circumstances, it is not without its problems. Natural language sentences can be complex; they can be ambiguous; and failing to understand the meaning of a sentence can lead to errors in reasoning. As an example of ambiguity, suppose I were t...
The existence of a formal language for representing information and the existence of a corresponding set of mechanical manipulation rules together have an important consequence, viz. the possibility of automated reasoningusing digital computers. The idea is simple. We use our formal representation to encode the premises of a problem as data structu...
Although Logic is a single field of study, there is more than one logic in this field. In the three main units of this book, we look at three different types of logic, each more sophisticated than the one before. Propositional Logic is the logic of propositions. Symbols in the language represent "conditions" in the world, and complex sentences in t...
Logic is the study of information encoded in the form of logical sentences. Each logical sentence divides the set of all possible world into two subsets - the set of worlds in which the sentence is true and the set of worlds in which the set of sentences is false. A set of premises logically entails a conclusion if and only if the conclusion is tru...
Exercise 1.1:Consider the state of the Sorority World depicted below. For each of the following sentences, say whether or not it is true in this state of the world. Exercise 1.2:Consider the state of the Sorority World depicted below. For each of the following sentences, say whether or not it is true in this state of the world. Exercise 1.3:Conside...
By the logical syntax of a language, we mean the formal theory of the linguistic forms of that language-the systematic statement of the formal rules which govern it together with the development of the consequences which follow from these rules. A theory, a rule, a definition, or the like is to be called formal when no
Syntax involves arranging words to create logical phrases, clauses, and sentences. This is a big topic, so we'll be covering a lot, including: dependent and independent clauses; simple, complex, compound, and compound-complex sentences; and phrases and clauses.
