What is a tautological argument?
A tautological argument is an example of circular argumentation.
The premise and the conclusion are one and the same.
The argument appears as in the form of both a proposition and its logical conclusion that is one and the same..
What is tautology in writing?
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 an example of pleonasm?
Example 1. I heard it with my own ears. When one hears something, we can presume it is with one’s own ears. The addition of “with my own ears” is a pleonasm.
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 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 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.
How do you identify tautology?
If you are given a statement and want to determine if it is a tautology, then all you need to do is construct a truth table for the statement and look at the truth values in the final column. If all of the values are T (for true), then the statement is a tautology.
What does tautological mean?
always and for ever1a : needless repetition of an idea, statement, or word Rhetorical repetition, tautology (‘always and for ever’), banal metaphor, and short paragraphs are part of the jargon.— Philip Howard. b : an instance of such repetition The phrase “a beginner who has just started” is a tautology.
What does Pvq mean?
is truev: This means “or.” The sentence (pvq) is true if and only if p is true, or q is true, or (p^q) is true. ->: This means “implies.” The sentence (p->q) is true if and only if the p is false or q is true (the sentence ((~p)vq) is true).
Are definitions always true?
Thus definitions (being only parts of such propositions) are not true or false.
What is oxymoron and give examples?
An oxymoron is a self-contradicting word or group of words (as in Shakespeare’s line from Romeo and Juliet, “Why, then, O brawling love! O loving hate!”). A paradox is a statement or argument that seems to be contradictory or to go against common sense, but that is yet perhaps still true—for example, “less is more.”
What is a anaphora sentence?
Anaphora (pronounced uh–naf-er-uh) is when a certain word or phrase is repeated at the beginning of clauses or sentences that follow each other. This repetition emphasizes the phrase while adding rhythm to the passage, making it more memorable and enjoyable to read.
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 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”.
What does Hypophora mean?
Hypophora, also referred to as anthypophora or antipophora, is a figure of speech in which the speaker poses a question and then answers the question.
What is the opposite of a tautology?
Tautology refers to a redundant use of language, “too many words”. The opposite of that would presumably be “not enough words”, excessive concision, terseness, insufficiency, curtness. 3. Contradiction refers to something going against something else.
How can tautology be prevented?
How to Avoid Tautology. In order to avoid using tautologies, pay careful attention to the logic of what you are writing. Often beginning writers cannot see what they have written as objectively as other people and may not notice tautologies, so you have to practice reading your writing as if you were someone else.
Are tautologies bad?
The Importance of Avoiding Tautology. Tautologies interrupt prose and conversation with unnecessary words. They also sound bad because they are a kind of mistake; it sounds like you meant to explain something, but instead you just said the same thing again, which can be confusing rather than helpful.
Are tautologies 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”.
Are tautologies valid?
If the premises of a propositionally valid argument are tautologies, then its conclusion must be a tautology as well. If the premises of the argument are tautologies, then they are all true under every assignment of truth values to the sentence letters. A valid argument with true premises has a true conclusion.
Is tautology a figure of speech?
A tautology is an expression or phrase that says the same thing twice, just in a different way. For this reason, a tautology is usually undesirable, as it can make you sound wordier than you need to be, and make you appear foolish. … Sometimes a tautology involves just a few words that mean the same thing.
