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.

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

The body is our general medium for having a world.

The flesh is at the heart of the world.

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.

We must therefore rediscover, after the natural world, the social world, not as an object or sum of objects, but as a permanent field or dimension of existence.

Science manipulates things and gives up living in them. It makes its own limited models of things; operating upon these indices or variables to effect whatever transformations are permitted by their definition, it comes face to face with the real world only at rare intervals. Science is and always will be that admirably active, ingenious, and bold way of thinking whose fundamental bias is to treat everything as though it were an object-in-general - as though it meant nothing to us and yet was predestined for our own use.
