**Liar Paradox (Eubulid or Epimenides Paradox)**- Back to the Paradoxes

This is a well known paradox written by the great stoical logician Chrysippos. The poet, grammarian and critic Philetus of Cos was said to have died of exhaustion attempting to resolve it.

**1st problem:**

A Cretan sails to Greece and says to some Greek men who are standing upon the shore:

"All Cretans are liars."

Is he lying or telling the truth?

**2nd problem:**

Read after resolving the first as this contains a massive hint.

2. Now assume that either all Cretans are liars or all Cretans tell the truth.

A Cretan states "All Cretans are liars and all I say is the truth."

Is he lying or telling the truth?

If someone says "I always lie", are they telling the truth? Or are they lying?

**Rational assumptions:**

A liar always tells lies, and a truth-teller always tells the truth.

If a person is not a liar, then they are a truth-teller, and vice versa.

This Cretan is not the only Cretan.

The two problems are of disjoint cases.
