Here, in a dialogue form, Rupert Sheldrake puts forward his developed argument that we could and should regard the Sun as alive and conscious - based on arguments he derives from physics, information theory and the like.
Also: Is the Sun Conscious on this page:
He goes on to draw out the implications of assuming the Sun is alive - what other things are therefore likely to be alive, and how they may influence us (and we them, presumably).
I think Sheldrake makes a decent case - from his Platonic/ Aristotelian/ Christian/ Biologist perspective - Although the reason why I myself regard the Sun as (in some way, poorly understood) alive, conscious and purposive is metaphysical rather than scientific: since we cannot draw a line between alive and not-alive, therefore either everything is alive or nothing is alive - therefore (since we know we personally are alive) everything is alive.
[PS: the other participant in the conversation, Mark Vernon, seems like what he actually is - primarily a secular Leftist activist who uses religious (often Christian) language and concepts. His understanding of Barfield is, consequently, partial and distorted.]
