Where is the Liar Paradox?

In philosophy and logic, the classical liar paradox or liar’s paradox or antinomy of the liar is the statement of a liar that they are lying: for instance, declaring that “I am lying”. If the liar is indeed lying, then the liar is telling the truth, which means the liar just lied.

How do you find the paradox?

A paradox is a statement that contradicts itself, or that must be both true and untrue at the same time. Paradoxes are quirks in logic that demonstrate how our thinking sometimes goes haywire, even when we use perfectly logical reasoning to get there. But a key part of paradoxes is that they at least sound reasonable.

When was the liar paradox created?

How many types of paradoxes are there?

Does there exist a set of all sets?

we can find a set that it does not contain, hence there is no set of all sets. This indeed holds even with predicative comprehension and over Intuitionistic logic.

Can a set be member of itself?

No: it follows from the axiom of regularity that no set can contain itself as an element. (Any set contains itself as a subset, of course.) And that’s a good thing, because sets containing themselves is exactly the kind of thing that leads to Russell’s paradox and other associated problems.

What is Russell’s barber paradox?

…to be known as the barber paradox: A barber states that he shaves all who do not shave themselves. Who shaves the barber? Any answer contradicts the barber’s statement.
