Slim Lover - Back to the Logic Problems
Something to relax. A slim young man asked a girl on a date:
"I say something. If it is truthful, will you give me your photo?"
"Yes," replied miss.
"And if it is a lie, do not give me your photograph. Would you promise that?"
The girl agreed. Then the chap said such a sentence, that after a little while of thinking she realized, that if she wanted to honor her promise, she wouldn't have to give him a photo but a kiss.
What would you say (if you were him) to be kissed and so on?

Spoiler for Solution:

Slim Lover - solution
You could say for instance this sentence: „You will give me neither your photo nor a kiss.“

That is slick.. i like it.

[tambay]

Nice move...
But why does the girl have to give a kiss? It's not part of the deal

[wewerehere]

she would have to kiss him because he said if the statement is true then give me a photo. since he said no photo and no kiss she doesnt have to give him a photo but to make it so that she doesnt have to give him a photo she has to give him a kiss. To keep the statement false

[savagegamer90]

coudn't you just say "you won't give me a kiss"
if she doesn't kiss you, you get a photo
but if she doesn't want to give you her photo she has to kiss you

[unreality]

but the statement rookie gave guarantees a kiss. See, without the kiss part of his statement, it would be:
"You will not give me your photo."
It's a paradox.

But if we have another part to it, it gives an opportunity to break out of the paradox to prove it wrong and still not give a photo, which is to kiss him.

think of it this way:

if the statement is true:
she will give neither photo nor kiss
But then she would have to give her photo because it was true. And then it would be false.

or if the statement is false: (meaning both true and false point to false)
she will give EITHER photo or kiss

But if she gives the photo, it would be true, so she can't do that. He gets kissed, no matter what.

"If you give me your photo, you'll give me a kiss!"

If yes, it's easy.
If no, that means the statement is false and if she gives him a photo, he doesn't get a kiss - but she does so she has to give him a kiss (I know this can be argued against) - this also means: if she doesn't give him a photo, she gives him a kiss.

Since precision is the turning point upon which these puzzles become feasable, let us remember that precise language is the cornerstone of makes logical precision. Therefore, while I not only grant, but applaud his use of the subjunctive case in the verb of to be; I might remind all that this is what some would refer to a type IV sentence in which the verb of to be restates the subject and the the subjective (or nominal) form of the pronoun should be used and the parenthetical should read, "if you were he".

Keep up the great work, all.

Now if only I could find a woman quick enough to work out the logic
