Several references have been made to images - eidola - that Epicurus says we perceive as eminating from objects that impact our senses and mental perception. I've reinterpreted this as light - for sight at least - bouncing from the object to our eyes. Light is constantly bouncing off objects and striking our eyes. If something produces sound or odors, those too will spread out and if we're in the way we encounter a sound or smell.
Now the idea of our minds perceiving concepts or encountering eidola independent of physical physical senses gets a little trickier. Although, look at those babies again "sensing" whether something is fair, or right or wrong. They're obviously "sensing" something coming from that experience. Although it's their sight that is allowing them to assess the situation, sight is not being used to determine the justice of the situation. This is one reason I'm inclined to think the mental Perceptions and Prolepses either work hand in hand or are the same thing by different names. The Mental Perceptions sense the "pattern" (to co-opt a phrase from Elayne ) but the Prolepsis puts it into a category or paradigm.
I think this has parallels to the Prolepsis of the Divine... But I'm still working on that! ![]()
