## What is the paradox?

A paradox, also known as an antinomy, is a logically self-contradictory statement or a statement that runs contrary to one’s expectation. It is a statement that, despite apparently valid reasoning from true premises, leads to a seemingly self-contradictory or a logically unacceptable conclusion.

## Why is tautology used?

Essentially, a tautology expresses the same thing, idea, or saying repeatedly. There are many reasons people use tautology in both everyday discussion and poetry, research papers, prose, and song lyrics. … Tautology can demonstrate derision, be used a poetic or literary device, or contain psychological significance.

## What does trivially true mean?

The term is also often used for statements that are ‘right for the wrong reasons’ in mathematics proper: whereas ‘ 2+x=4, therefore x=2 ‘ is true, ‘ 2+2=x, therefore 4=4 ‘ is trivially true.

## What is the word for unnecessary?

worthless, needless, superfluous, gratuitous, redundant, useless, avoidable, unneeded, irrelevant, futile, accidental, additional, beside the point, casual, chance, dispensable, excess, exorbitant, expendable, extraneous.

## What is the main difference between tautology and contradiction?

A tautology is a statement that is true in virtue of its form. Thus, we don’t even have to know what the statement means to know that it is true. In contrast, a contradiction is a statement that is false in virtue of its form.

## Is tautology a fallacy?

A tautology in math (and logic) is a compound statement (premise and conclusion) that always produces truth. No matter what the individual parts are, the result is a true statement; a tautology is always true. The opposite of a tautology is a contradiction or a fallacy, which is “always false”.

## Why is tautology wrong?

The standard criticism of tautologies goes like this: because of the the fact that tautologies are necessarily true, they do not tell us anything new about the world. They cannot possibly be wrong; therefore, they do not add to our knowledge. They are redundancies, and they ultimately do not need to be stated.

## What are 2 words that mean the same thing?

If two words are synonymous, they mean the same thing.

## What does tautology mean in logic?

In logic, a tautology (from Greek: ταυτολογία) is a formula or assertion that is true in every possible interpretation. An example is “x=y or x≠y”. A less abstract example is “The ball is all green, or the ball is not all green”.

## What does P → Q mean?

A proposition of the form “if p then q” or “p implies q”, represented “p → q” is called a conditional proposition. … The proposition p is called hypothesis or antecedent, and the proposition q is the conclusion or consequent. Note that p → q is true always except when p is true and q is false.

## Is tautology always true?

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”.

## What is an example of 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.

## What is the difference between tautology and pleonasm?

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.

## Why is a tautology useless for logical argumentation?

An argument requires support for an idea where as a tautology is merely a repetition/rephrasing of an idea. If a tautology was posed as an argument it would be an invalid one because it doesn’t support the idea any further, not because it is logically incorrect.

## What is a tautology statement?

A tautology is a logical statement in which the conclusion is equivalent to the premise. More colloquially, it is formula in propositional calculus which is always true (Simpson 1992, p. 2015; D’Angelo and West 2000, p. 33; Bronshtein and Semendyayev 2004, p. 288).

## How do I know if I have tautology?

If you are given any statement or argument, you can determine if it is a tautology by constructing a truth table for the statement and looking at the final column in the truth table. If all of the truth values in the final column are true, then the statement is a tautology.

## How do you get rid of tautology?
