,André Malraux: 1901–45 and 1945–76,ional pseudo-Riemannian manifold) and that gravity should not be regarded as a force in the conventional sense. To get a preliminary idea of what is involved, we shall follow the practice of a number of authors. and consider ants crawling over a curved surface, namely the skin of an apple.

Andre Gorz and the Sartrean Legacytation does not mean that H.G. Wells’ Mr Cavor could now introduce an antigravity material and glide up to the Moon, nor, for example, that we might produce intense permanent gravitational fields in the laboratory, as we can electric fields. It means only that all the properties of gravity of which

This solution is asymptotically flat, and in no way incorporates the gravitational effects of distant matter in the Universe. Nevertheless, it seems reasonable to adopt it as a model for the gravitational field in
