A cloud: thing and atmosphere at once
The human eye perceives by detecting light. The human brain perceives in a way still not fully understand. Some theories say that the brain directly interprets the light detected. It is known that parts of what we are conscious of perceiving come from reconstructions—our brain filling in the gaps. This is called object permanence, or it is the way we can have frontal eyes, but perceive periphery. Some theories say that there is nothing direct about seeing; instead, the light we detect is combined with all the other images and waves of light we have ever perceived, measuring up against schemas. Habitual perceptions are what allow us to see at all, but they also limit and shape what we see.
