For if one regards space and time as properties that, as far as their pos sibility is concerned, must be encountered in things in themselves, and reflects on the absurdities in which one then becomes entangled, be cause two infinite things that are neither substances nor anything really inhering in substances must nevertheless be something existing, indeed the necessary condition of the existence of all things, which also remain even if all existing things are removed; then one cannot well blame the good Berkeley if he demotes bodies to mere illusion; indeed even our own existence, which would be made dependent in such a way on the self subsisting reality of a non entity such as time, would be trans formed along with this into mere illusion; an absurdity of which no one has yet allowed himself to be guilty.
