Spectral machines ...

... More Than Matter? by Keith Ward | Philosophy Now. (Hat tip, Dave Lull.)

Ward inclines, then, to an idealism which gives priority to mind – what he calls ‘dual-aspect idealism’: minds are the inner aspect of an apparently-material person, living in an apparently-material world. “What the reality underlying those appearances may be in detail we do not know,” he continues. “But since minds are the only sorts of reality we know to belong to the world of things-in-themselves, it is reasonable to think that reality does not exist without mind and consciousness, evaluation and intention, understanding and action … Minds are not illusory ghosts in real machines. On the contrary, machines are spectral, transitory phenomena appearing to an intelligible world of minds.” This leads Ward to further reflections on issues such as whether the universe can be said to have purpose, the nature of what it is to be a person, and whether minds can exist in disembodied forms.
