That mind, moreover, does not require space in order to carry on its movements agreeably to its nature, is certain from observation of our own mind. For if the mind abide within its own limits, and sustain no injury from any cause, it will never, from diversity of situation, be retarded in the discharge of its functions; nor, on the other hand, does it gain any addition or increase of mobility from the nature of particular places.(Book I, Part 6)

Origen is mostly, I think, focused on the locus of the mind, suggesting that a mind-without-body is limitless.

I am less able to conceive of a mind-without-brain than perhaps was possible for Origen and in this way may be more limited than he.

I perceive my mind begins in caring for my body, mostly by making sense of the physical space in which it finds itself.

From this very practical beginning a great many possibilities emerge.

As my mind-and-body engage the space in which I find myself I perceive - even only vaguely - internal and external evidence of a reality beyond immediate reality.
