The Paradox is in the description.

After watching this paradoxes don't seem like a mystery any more! :-)

Suppose there is man living in the village who is the barber. Suppose further that there exists a binary relation 'shaves' defined on the set of all men in that village such that the barber 'shaves' those and only those men in the village who do not shave themselves. You can resolve the resulting paradox by showing that no such relation can exist. See my video, "The Barber Paradox, A Mathematical Analysis."

@suzywao The paradox you're thinking is: "if a person prevents his own birth, then wouldn't be able to prevent his own birth", right? The problem is that you're examinating the description, not the situation! You have to imagine what it would would work like: time flows.
If you kill your grandfather time would simply go on in a different reality where you were never born.

Vin Diesel? Where is Vin Diesel? I only see Bruce Willis there!

wow i didnt know vin diesel was so smart

haha i like the vid its funny and makes sense

A paradox is just a subjective description created inside the box of thinking - nothing more.

@suzywao If time travelling were possible, you still wouldn't have a paradox. Suppose a man were born today. In 2030 he goes back in time, kills grandfather in the year 1960. Thus, he will not be born in the year 2010. The problem here is our concept of time. We see it as if 1960 lies before 2010, while actually for this man there is a 1960 that existed before his birth, then 2010, 2030 and afterwards a different time that is CALLED 1960. This man was born 20 years before this different 1960.

Faster in relation to what? Actually since I asked the question I found an answer, but yours isn't it.
This particular paradox is due to the description but not all paradoxes are. Some are absolutely independent.
This only applies to one type of paradox.

I only used this one type of paradox as an illustration, but all paradoxes are in the description. The concept of "paradox" is something that can only apply to descriptions.
There are no paradoxes in the "real world". The paradoxes only arise in describing the "paradoxical situation". My example was to show that even when you "solve a paradox" the original situation remains unchanged.
I challenge you to find a paradox that is somehow independent of its description.

Great video too! 5/5 I like how you ended the video too.
