Encyclopedia of Philosophy: Alexander, Samuel

The time dimension of Space-Time gives things an internal aspect as going through a process, while the space dimension sets them in an external relation called 'compresence'. A subject's inner experience of knowing is called 'enjoyment' and its relation of compresence to an object is called 'contemplation'. This is a direct realism, which raises difficulties over questions of error and counterfactual conditions. This realism extends to secondary qualities, such as colours. Besides secondary qualities there are 'tertiary' qualities called values, which arise in situations where one compresent factor is a mind. Chief of these are Truth, Beauty and Goodness.
