Will now post my Ancient Greek Paradox puzzle and see how you get on with it and you will see why it is classed as a paradox.
"The Law student’s dilemma"
The teacher Protagoras agrees to take the penniless Euthalus as his student on condition that Euthalus pays him for his tuition upon winning his first court case.
Later (after a few years of tuition with Euthalus now practising on his own) and impatient for his money, Protagoras sues Euthalus for it, even though Euthalus has not yet won a case.
Protagoras argues that if he wins the case, he will be owed the money, and if Euthalus wins the case, he is still owed the money on the terms of the original contract.
Euthalus, on the other hand, claims that if Protagoras wins the case, Euthalus still hasn’t won a case, so he cannot be due to pay. If he (Euthalus) wins the case, the terms of the original contract are voided, so he still does not have to pay.
Who is right, Protagoras or Euthalus?
(If you think along the lines of how the court would rule on the situation, plus any subsequent response or action by either party, that might help)
Will provide the most likely outcome after Christmas.
