More seriously though, nowadays when people call themselves Epicurean, they mean just the life philosophy stuff, not the physics stuff :D

Depends on what you mean. Obviously plants and photosensitive tissues have been sensing light for a long time, millions of years. But hose aren't eyes, and most wouldn't even call that poor sight.
A baby human usually has its eyes closed at birth, and the brain isn't completely formed until 25 years old. It takes at least a few years after birth for all the basic parts to settle in and get developed. So does a baby have sight if it hasn't yet used it's immature eyes? Does it truly process what it "sees" into anything meaningful in the beginning?
If there is a spirit that exists before life, does it "see" and with what?
So, then you're agreeing -- the sensory organ is developed first before the sensor is active
Hmmm, yeah, I suppose broadly (unless souls exists). If a creature evolves like... a dozen photosensitive patches, like a proto-spider, would we say that creature has sight but no eyes? If that's the case, do compound "eyes" actually count?
I guess now I'm just musing on where the fuzzy line is between a bunch of eyelets and eyes (made up of single-celled photreceptors). I think sight is just what eyes do. Something like "insight" comes from a metaphor ("looking" within) and I... don't know if there's a different word for like... what the experience of being a plant and sensing the sun on your leaves would be called?
