Meno Dilemma

Tractatus logico-philosophicus

6.5

For an answer which cannot be expressed the question too cannot be expressed.

The riddle does not exist.

If a question can be put at all, then it can also be answered.

Tractatus Logico-Philosophicus 6.5

This is also known as MENO dilemma  It goes something like this. If you ask a question, you already know the answer. You may argue you do not know the answer. Then, again, how can you ask the question in the first place.
