I like the view of it as being some physically indiscernible, yet all too real, connection between two people. Such as it's described in the book “Xenocide”, by Orson Scott Card, where it talks about 'philotic connections.' Not that I view it quite that way. And there is the issue with needing to have some degree of knowledge in order to truly effect love between two beings. Intelligence, or knowledge about the being, seems to be a requisite to the degree and capacity to effect love. Whatever that means.
Any other thoughts on this? This is much to big for a single post. Heck, it's too much for a single internet's worth of discussion.
