Truth, Lie and Wisdom - Back to the Logic Problems
Three goddesses were sitting in an old Indian temple. Their names were Truth (always telling the truth), Lie (always lying) and Wisdom (sometimes lying). A visitor asked the one on the left: "Who is sitting next to you?"
"Truth," she answered.
Then he asked the one in the middle: "Who are you?"
"Wisdom."
Lastly, he asked the one on the right: "Who is your neighbor?"
"Lie," she replied.
And then it became clear who is who.

Truth, Lie and Wisdom - solution
Let’s assign a letter to each goddess. We get these sentences.
1. A says: B is Truth.
2. B says: I am Wisdom.
3. C says: B is Lie.
First sentence hints that A is not Truth. Second sentence is not said by Truth either, so C is Truth. Thus the third sentence is true. B is Lie and A is Wisdom.

Spoiler for old wording

Three goddesses were sitting in an old Indian temple. Their names were Truth (always true), Lie (always lying) and Wisdom (sometimes lying). There was the following conversation:
Asking the left one: "Who is sitting next to you?"
"Truth," she answered.
Asking the middle one: "Who are you?"
"Wisdom."
And at last question for the right one: "Who is your neighbor?"
"Lie," she replied.
Now it is clear who is who.

you just made my brain spasm.

I used a similar method to solve this, but used the following to help.

Write all combinations of orientation and rule them out one by one. Easy!

Truth - T, Wisdom - W, Lie - L:

T W L - Truth would not lie about Wisdom's position.
T L W - Same reason as above.
L T W - Lie would lie about Truth's position.
L W T - Truth would not lie about Wisdom's position.
W T L - Truth would not lie about its own position.
W L T - Voila!

It could have been explained more clearly by saying that:

Truth is neither the one on the left or the middle since she won't lie about who is beside her or who she is. Therefore, she is on the right side and she was telling the truth that Lie was her neighbor, in the middle. That leaves Wisdom on the left.

WISDOM -- LIE -- TRUTH

What do you think guys?

I thought the answer was Truth-Lie-Wisdom.
Could it be that Wisdom told a lie saying that truth was to the right of it. That means that lie has to be to the right. That leaves truth, who says that lie was a neighbor. That is the truth. Of course, I guess there are alternate solutions.

The first one can't simultaneously be truth and say that her neighbor is truth. I believe there's only one solution.

I thought of it this way:

A--B--C

Start with the possible options for person B:
B says that it is Wisdom, therefore it can either be Lie or Wisdom, but can't be Truth.

Person A:
A says that the person to the left is Truth, which we now know is a lie, therefore, A is either Lie or Wisdom aswell.

Person C:
Because neither A or B can be Truth, it has to be Truth, therfore, person C saying that the person to the left is Lie, is a truthful statement.

Thus, B is known to be Lie and that leaves person A being wisdom

A-wisdom, B-Lie, C-Truth

I completely agree and logically, this is exactly how I came to the same conclusion.

Great job!

This one was pretty easy. Finding "truth" first was the way to go.

[cawebster]

I found Lie first.

L = Left, M = Middle, R = Right

M - Can't be Wisdom because that means both the other two are lying.
If M were Wisdom one of the other two would be Truth and therefore couldn't lie.

M - Must be Lie since she claimed to be Wisdom and this is obviously not true.

L - Must be Wisdom because she is the only other capable of lying and she claimed M is Truth.

R - Has to be truth because the other two lied.
