These comments don't make sense, or are inaccurate.

So the other day I was sitting in one of my classes bored out of my mind, when I had the great idea to hop on Wikipedia on my phone, and start researching some things I really enjoy, psychology and philosophy. After awhile I stumbled upon some articles on paradoxes and found them highly interesting. I thought to myself "This would make for a fantastic thread", so here we are. The objective here is to post the best paradoxes you can either find, or think up. I'll get us started with a few classics:


"This statement is false."
Explanation: If the statement is truthfully false, then it is true, thus making it a contradiction.

"What I am saying now is a lie."
Explanation: If it truly is a lie, then it is truth, thus being a contradiction.

"I know that I know nothing."
Explanation: If you honestly know nothing, then you would be unaware of the fact that you know nothing. This goes hand in hand with the fact that you cannot be aware of the basis in which you are ignorant to something, because then you truly aren't ignorant to it.

"A single grain of sand is certainly not a heap. Nor is the addition of a single grain of sand enough to transform a non-heap into a heap: when we have a collection of grains of sand that is not a heap, then adding but one single grain will not create a heap. And yet we know that at some point we will have a heap."
Explanation: This one is a bit more complicated, considering that there is no exact point at which we definitively call something a heap. Due to this fact, the sand can be considered, at a point, as being both a heap, and not a heap. Following this train of thought, it would either be considered both a heap and not a heap simultaneously, or it would be neither simultaneously.

Hahahaha, yes. I am a great fan of that thought experiment. It really makes you think, and somewhat leads into another good paradox, one which I believe to be one of the most true and applicable paradoxes to reality.

The Observer's Paradox: The outcome of an event or experiment is influenced by the presence of the observer.

The ideal man is the epitome of paradoxes.

Sensitive yet assertive.

Humble yet confident.

Rich yet not materialistic.

Strong yet vulnerable.

Kind yet aggressive.

It will go on until a woman is finally satisfied

Hahahaha, I thought about this one the other day when I was trying to decide at which point I could consider my computer, which I built and have been adding to and replacing components of over time, as no longer being the same computer and at which point I should hold a proper memorial for him. He has served me well! Anyways, I'll leave with another few paradoxes:

"It is opposite day today."
Explanation: If it truly is opposite day, then you could not state such without it being false, but if it is a normal day, then it still would not be true.

"In any pub there is a customer of whom it is true to say: if that customer drinks, everybody in the pub drinks."
Explanation: A bit difficult to explain; what this deals with is the fact that if all customers are drinking, then if even one stops, you could no longer state that all customers are drinking. On the other side of that, even if not everyone is drinking, this could still be stated due to the fact that whoever is not drinking would have to start doing so to make it be true that all are drinking.

The "What the Tortoise Said to Achilles" Paradox: This one has a very long scenario, go to https://en.wikipedia.org/wiki/What_the_Tortoise_Said_to_Achilles to read it. What it essentially shows is the impossibility to use logic to force the belief of a premise and its logical conclusion using the transitive property. If one is to deny the premise, then even if they accept the conclusion it leads to, there is no way of proving the premise.
