Where does the word tautology come from?

Etymology. From Late Latin tautologia, from Ancient Greek ταὐτολογία (tautología) from ταὐτός (tautós, “the same”) + λόγος (lógos, “explanation”), analyzed as tauto- +‎ -logy.

What is the difference between tautology and pleonasm?

Difference between pleonasm and tautology

Pleonasm has a sense of using an unnecessary overabundance of redundant words in one description. Tautology has a sense of saying the exact same in different words, using multiple words with the same meaning.

What is tautology vs axiom?

Tautology: A statement that is proven to be true without relying on any axiom. Axiom: A statement that is assumed to be true without a proof or by proof using at least one axiom.

Is a tautology a paradox?

No. A paradox doesn't just assert something incorrect (e.g. "0≠0") - it asserts something which cannot be consistently assigned a truth value. Just implying the negation of a tautology doesn't mean that a statement is paradoxical: e.g. "p and ¬p" is not a paradox, it's just a false statement.

What is opposite of tautology?

A tautology is a statement that is necessarily true, and a contradiction is a statement that is necessarily false.

What is Pleonastic?

/ˌpliː.əˈnæs.tɪk/ using more words than are needed to express a meaning, either unintentionally or for emphasis: The prose is often pleonastic in nature. Some pleonastic phrases, such as "tuna fish" or "advance reservation," become part of normal idiom. Related word.

Is tautology an oxymoron?

Notes: A tautology is the opposite of an oxymoron, two words that contradict each other, such as the living dead. The words of a tautology mean the same thing: a dead corpse is a tautology because corpse itself means "dead".

Is tautology opposite of oxymoron?

Answer and Explanation: A tautology is opposite of an oxymoron. Where an oxymoron is a phrase that sounds contradictory, a tautology is a phrase that is redundant. Each word in the tautology means the same thing.

What is common English tautology?

Tautology is the use of different words to say the same thing twice in the same statement. 'The money should be adequate enough' is an example of tautology.

What is the simplest tautology?

If it's more about the outcome, a tautology simply means, it's always true. So "True" (TRUE, true, 1 or whatever, depending on language or field) would be the simplest tautology value wise, while "False" would be the simplest contradiction by the opposite line of reasoning.

Is P ∧ Q → P is a tautology?

Clearly from the truth table, we can conclude that the truth values of p∨(p→q) and (p∧q)→q are always true. Hence, they are tautology.

Is all false a tautology?

A tautology is a formula which is "always true" --- that is, it is true for every assignment of truth values to its simple components. You can think of a tautology as a rule of logic. The opposite of a tautology is a contradiction, a formula which is "always false".

Is every logical truth a tautology?

All tautologies are logical truths. Not all logical truths are tautologies. A sentence is TT-possible if its truth table contains at least one T under the main connective.

Is begging the question a tautology?

Used in this sense, the word beg means "to avoid," not "ask" or "lead to." Begging the question is also known as a circular argument, tautology, and petitio principii (Latin for "seeking the beginning").

What is dialectical vs paradox?

Whereas paradox research depicts tensions between contradictory elements as irreconcilable and best managed through acceptance and synergy, the dialectical perspective portrays the relationship of such elements as adversarial and transformed through conflict.

What is the difference between syllogism and tautology?

A false syllogism is one in which the conclusion is invalid because it is hidden somewhere in the premises. Tautology:A statement that seems to impart new information but actually repeats what is already known. For example: 'This cat was extraordinarily feline', meaning 'this cat was unusually cat-like'.

Who coined the term tautology?

The term itself, however, was introduced by the Austrian-born British philosopher Ludwig Wittgenstein, who argued in the Logisch-philosophische Abhandlung (1921; Tractatus Logico-Philosophicus, 1922) that all necessary propositions are tautologies and that there is, therefore, a sense in which all necessary ...

Is P ∧ Q → P is a tautology?

Clearly from the truth table, we can conclude that the truth values of p∨(p→q) and (p∧q)→q are always true. Hence, they are tautology.

Is tautology an oxymoron?

Notes: A tautology is the opposite of an oxymoron, two words that contradict each other, such as the living dead. The words of a tautology mean the same thing: a dead corpse is a tautology because corpse itself means "dead".

Is tautology grammatically correct?

What's a tautology? In grammatical terms, a tautology is when you use different words to repeat the same idea. For example, the phrase, “It was adequate enough,” is a tautology. The words adequate and enough are two words that convey the same meaning.

Is every logical truth a tautology?

All tautologies are logical truths. Not all logical truths are tautologies. A sentence is TT-possible if its truth table contains at least one T under the main connective.

What is the synonym of tautology?

verbose. adjectivewordy, long-winded. bombastic. circumlocutory.

What is the difference between syllogism and tautology?

A false syllogism is one in which the conclusion is invalid because it is hidden somewhere in the premises. Tautology:A statement that seems to impart new information but actually repeats what is already known. For example: 'This cat was extraordinarily feline', meaning 'this cat was unusually cat-like'.

Is [( P ∧ Q → R → P → Q → R )] tautology?

Hence, from the above truth table, we can conclude that [(p⇒q)∧(q⇒r)]⇒(p⇒r) is a tautology, as it's truth value's are always true.

What does P ∧ Q mean?

P ∧ Q means P and Q. P ∨ Q means P or Q. An argument is valid if the following conditional holds: If all the premises are true, the conclusion must be true.

Is P → Q → (( P → Q → QA tautology?

Since all the values in the last column are true, hence the given statement is a tautology. Was this answer helpful?

Is tautology always false?

In logic, a formula is satisfiable if it is true under at least one interpretation, and thus a tautology is a formula whose negation is unsatisfiable. In other words, it cannot be false. It cannot be untrue.
