When something is neither true or false?
The answer you are looking for is “undecidable”. What is neither true nor false is called an undecidable proposition. This is about the liar paradox and Gödel’s incompleteness theorems. Every attempt to establish the truth of the first proposition leads to a contradiction in the second.
Can something be not true and not false?
In the classical logic something is neither true nor false if it is grammatically malformed to have a truth value, so 2+5 or “x is blue” are not “true”, but not “false” either, they are not truth-apt.
Can a sentence be neither true or false?
Summary. In summary, statements are the kind of sentences that are either true or false. Sentences are ambiguous when they can be used to express several statements. When you have an ambiguous sentence, you need to decide which statement it is being used to express.
Can something be true and not true?
Dialetheism (from Greek δι- di- ‘twice’ and ἀλήθεια alḗtheia ‘truth’) is the view that there are statements which are both true and false. More precisely, it is the belief that there can be a true statement whose negation is also true. Such statements are called “true contradictions”, dialetheia, or nondualisms.
Is paradox True or false?
A paradox 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.
What is a statement that is either true or false but not both?
a sentence that is either true or false, but not both. It is also called a proposition. Negation: if p is a statement variable, the negation of p is “not p”, denoted by ~p.
What is the meaning of Pvq?
p v q stands for p or q That is: p v q iff at least one of p or q is true. Note that they may both be true. p ↔ q or p ≡ q stands for p iff q That is: p ↔ q iff either both p and q are true or both p and q are false, i.e. p has the same ‘truth value’ as q.
How do you negate an or statement?
One thing to keep in mind is that if a statement is true, then its negation is false (and if a statement is false, then its negation is true).
|“A or B”
|“not A and not B”
|“A and B”
|“not A or not B”
|“if A, then B”
|“A and not B”
|“For all x, A(x)”
|“There exist x such that not A(x)”
What is negation of a statement?
In Mathematics, the negation of a statement is the opposite of the given mathematical statement. If “P” is a statement, then the negation of statement P is represented by ~P. The symbols used to represent the negation of a statement are “~” or “¬”. For example, the given sentence is “Arjun’s dog has a black tail”.
What is the difference between oxymoron and paradox?
An oxymoron is the conjunction of two words with meanings that contradict each other. While a paradox is the opposition of ideas or themes, an oxymoron is a contradiction merely between words. An example of oxymoron in literature can be found in William Shakespeare’s Romeo and Juliet.
What are the 3 types of paradoxes?

- Falsidical – Logic based on a falsehood.
- Veridical – Truthful.
- Antinomy – A contradiction, real or apparent, between two principles or conclusions, both of which seem equally justified.
What is a antinomy paradox?
An antinomy [a paradox] of logic takes place when two contradictory. statements A and – A are derived, or equivalently A == (- A) is derived, without committing a simple logical error.
Why are there antinomies?
Immanuel Kant, the father of critical philosophy, in order to show the inadequacy of pure reason in the field of metaphysics, employed the word antinomies in elaborating his doctrine that pure reason generates contradictions in seeking to grasp the unconditioned.

What is pragmatism in research?
Pragmatism involves research designs that incorporate operational decisions based on ‘what will work best’ in finding answers for the questions under investigation and this enables pragmatic researchers to conduct research in innovative and dynamic ways to find solutions to research problems.
What is Objectivism in research?
First, objectivism is an approach to knowledge/science that denies the systematic significance of the meaningful structuring of society. The role of mind, and thus of meaning in the social world is ignored. Second, objectivism is a view that rejects knowledge as a social product.
