Really? I didn’t know that! What is it called? How can I use it?

Philosophy is fine and all but we can’t forget that from a practical standpoint, all this philosophizing is useless. We can’t live our day to day lives operating under the belief that the material world doesn’t exist and using The Problem Of Knowledge as a way to dismiss empirical evidence by stating that we can’t be sure if the material world even exist is impractical and useless. Remember: Philosophy is completely useless. The only value you will find in it is the development of critical thinking skills.

Just imagine if a murdered caught red handed could get away scoot free by just saying “Hey, you can prove the material world exist, therefore you can prove the victim ever existed!”

It’s the problem of knowledge all over again. Something which philosophers have been debating for centuries. But I highly doubt you have studied any of it.

That whole thing of “facts are just opinions” is nothing more than the devaluing of empirical evidence and turning observable facts into a matter of opinion, turning any and all political discussion into a shouting match where nothing ever comes of it because “it’s just my opinion”. This propaganda tactic is called “The Fire hose of Falsehood”.

I could go on and on about the nature of knowledge and the evolution of science, but I highly doubt you would care as you do not seem to know even the most basic things about The Problem of Knowledge and choose to go the self-contradictory skeptic route of “Knowledge doesn’t exist”.

Edit: I would just like to add that just because our sense are 100% reliable that doesn’t mean that everything is false.
