Paradoxes | The Philosophy Student

In 2002, I learnt about paradoxes.

This is content from a book called, Vicious Circles & InfinityAn Anthology of Paradoxes by Patrick Hughes & George Brecht.

To start off, they explain that there are self-referential propositions, contradictory propositions, self-contradiction propositions which are not paradoxes & other forms of self-reference & contradiction of a “stronger” kind which approach the paradoxical state.

Example of a Self-Referential Proposition =

This sentence has five words.

Example of a Contradictory Proposition =

Round square.

Example of a Self-Contradiction Proposition =

This sentence has six words.

Here’s an example of the Self-referential & Contradiction that heads toward a paradox =

Please ignore this notice.

So, to do what this notice says, you mustn’t have done it.

However paradoxical, this one isn’t a paradox. A paradox has the self-reference and contradiction but it also contains a third factor = vicious circularity.

‘Please ignore this notice,’ goes round, but it doesn’t continue going round.

Other examples of this kind of paradoxical propositions are =

All rules have exceptions.

In principle, I am against principles – Tristan Tzara

No general proposition is worth a damn! – Oliver Wendell Holmes, Jr.

Never say never.

Check this out =

How can a witness reply to a lawyer who says = “Please answer yes or no to the following question: will the next word you speak be ‘no’?

If he answers ‘yes’ – it contradicts it.

If he answers ‘no’ – it contradicts it.

Other examples of this kind of ‘not quite paradoxes’ =

All generalisations are dangerous, even this one. – Dumas Fils

It is forbidden to forbid.

FULL PARADOX =

The Barber of Melbourne:

A man of Melbourne, Australia is shaved by the barber of Melbourne if & only if the man does not shave himself.

Does the barber of Melbourne shave himself?

If he does, he doesn’t & if he doesn’t, he does.

I’ll leave you with this =

The Liar Paradox:

Eubulides, an ancient Greek philosopher invented the liar paradox.

A Cretan says, “All Cretans are liars.”

If he is telling the truth, he is lying.

If he is lying, he is telling the truth…

Does God really exist? How would we know? Can we really know? And if there is a God, can there be such a being as 'MetaGod', that is...
