The space that surrounds me is not a piece of neutral, extended manifold, determined by a Cartesian system of co-ordinates. Experienced space is action-space; it is my space of action. To it, I am related through my body, my limbs, my hands. The experience of the body as mine is the origin of possessive experience.1

In experiencing, man finds himself always within the world,
directed toward it, acting and suffering.2
