A Perception is a mode of engagement with the world done so as to retrieve useful information about its orientation (such that a subject can be oriented in a situation, a world).
Perception is a living communication with the world such that when I see an object, I am barely aware of my seeing, but rather wholly engrossed by the object.
Perception is a kind of perceptional realism that states that consciousness is publically graspable and in principle correctable by the experience of others.
A Perception is a dialectical relationship between the world and us: It is what makes the world appear to us, and at the same time that which reveals to us that we are in the world.
A Perception is a perception with the body. To perceive is to inhabit time and space with our bodies. We are bodies-within-the-world such that, even when our body is extended, like a blind man's stick, the stick is not a middle term but a part of his bodily perception. His sense of touch is at the stick's end.
A Perception is an act that happens in wholes, not in elementary sensations. We see a person as a whole, rather than a collection of body parts. We greet a person as a whole rather than greeting first the outstretched hand.
Perception is already influenced by a far more invasive and pervasive pedagogy of habitus which is neither in people's minds, nor even bodily.
Perception is always true. That is, insofar as perception is subjective, if the thing being looked at is looked at, then it is looked at properly... it can only be perceived in that way.
