Ideas are created and ideas don’t come from something they come from someone, they are not arrangement of something, and ideas are very real to people, they even die for it or do stupid things or build a big cities and countries because of it. Every war and every building on this plant were fought or build because of an idea. Forms are created and building or sculpture wouldn’t be there if someone didn’t create them. Spaces are created and space is very real you can check it out by going into a small apartment or going into a large lobby or just going to the beach.
