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 world is... the natural setting of, and field for, all my thoughts and all my explicit perceptions. Truth does not inhabit only the inner man, or more accurately, there is no inner man, man is in the world, and only in the world does he know himself.

The phenomenological world is not the bringing to explicit expression of a pre-existing being, but the laying down of being. Philosophy is not the reflection of a pre-existing truth, but, like art, the act of bringing truth into being.

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

The flesh is at the heart of the world.

The photograph keeps open the instants which the onrush of time closes up forthwith; it destroys the overtaking, the overlapping, the metamorphosis of time.

All thought of something is at the same time self-consciousness [...] At the root of all our experiences and all our reflections, we find [...] a being which immediately recognises itself, [...] and which knows its own existence, not by observation and as a given fact, nor by inference from any idea of itself, but through direct contact with that existence. Self-consciousness is the very being of mind in action.
