  • Here is a description of research on aphantasia-- where people can't generate internal imagery, including for memories https://theconversation.com/bl…n-their-imagination-86849 -- I bring this up because we were wondering what the process would be whereby people would decide which images they wanted to see, in Epicurus' model. The folks with aphantasia do have memories but the images don't show up for them. And they mention how internally generated images are thought to occur-- by a network which…
  • Cassius that's a bad headline on the laser article, lol. It is not talking about extrasensory transmission of ideas but about a way to cause sound waves to occur at a specific distant place, using lasers. Ears would be necessary for the message to be heard! 😉 There's nothing in those references to memory that says internal images are involved-- and that's partly why I linked to the article on aphantasia. Memory and remembered images are not inseparable-- a person can remember events even if una…
  • I'm confused as to why you would want Epicurus to have included image storage in his model when he hasn't said it _and_ it wouldn't square with our observations of the brain? Considering he thought of images as these physical film structures, they would have to get crammed into the brain like a filing cabinet, and nothing of that sort happens-- no sheets of photons are being stored in the brain. He said they were very fine so there was room for them in the air... but the images of a lifetime all…
  • I am objecting to attributing ideas to Epicurus that he didn't state, especially when those ideas are wrong! He clearly describes visual images as being made of particles and imagined images as being made of even finer particles, both thrown off as films from objects. He never says we store those particles in our minds, and that whole idea is even wilder than having them available to re-enter. When we remember images, we are not pulling particles of what we saw back out of storage to view. Visua…
  • Besides that, when he explains visualizing (imagination) of an actual type of thing as images re-entering, that whole process relies on memory! If I want to think of a cow, how would I do it without memory of what a cow looks like? And he said that is a process of deciding to see the thing and that image is instantly available. Not that the memory of what a cow looks like comes from inside a storage in the mind!
