Never mind, I found the way through. First hit the button on the wall in the same room as the unstable pillar. Go through the opened up area. The wall in front of the stair case to the chest is the next doorway. Interact with the wall there. It will open up. There is another button on the wall that will drop the pillar.

I think I saw a post that someone was having trouble with the nonsensical riddle puzzle. The random sentences on the plaques have numbers in them. The pumpkin has first in it, so it is first. Two more have three and fourth in them, so those are third and fourth. I don't remember which are the second and fifth options, but that leaves you with only two options. Good luck!

thanks for posting that
