It is the essence of certainty to be established only with reservations.

Our body is not in space like things; it inhabits or haunts space. It applies itself to space like a hand to an instrument. And when we wish to move about, we do not move the body as we move an object.

Our own body is in the world as the heart is in the organism: it keeps the visible spectacle constantly alive, it breathes life into it and sustains it inwardly, and with it forms a system.

The body is to be compared, not to a physical object, but rather to a work of art.

Because we are in the world, we are condemned to meaning, and we cannot do or say anything without its acquiring a name in history.

We know not through our intellect but through our experience.
