"something immeasurable that is who we are, and that something interacts with our bodies and interprets the sensations from our bodies, but is still separate to our bodies. And this thing - essence, mind, identity - can have a gender and that gender can be different to the sex of the body"
Yes, this is indeed an example of "metaphysical fantasy" I mentioned in the earlier thread.
There are lots of problems with it, some of whose expressions in writing go back over two-and-a-half thousand years. (How does this something interact with bodies? (Plato's Parmenides asked this of young Socrates; René Descartes said the pineal gland did the trick but omitted to say how it did so: he knew nothing about melatonin, of course ... oh and so on and so on.)
What is new is the idea of gender attached somehow to this something. What is this gender? not sex, but something that can be different to - and hence possibly the same as - sex (and sex "of the body" (!)) though a part of this detached non-bodily something. Huh?
No, Spooky, none of this makes any sense. (Interesting though it be that you think it does.)
But, well, neither does much religious metaphysics. 'Substance' vs 'Accidents', anyone? Ghosts? Angels? Auras? ... Let's not go there.
The difference, as others have said, is that we have learned to deal with old-fashioned religious metaphysics. "Some people believe ... " the teachers tell the children; the children (well, mine and others) learn it's polite only to giggle behind one's hand and not aloud. You can be friends with people in spite of their strange beliefs. We rub along.
-- But this gender metaphysics is far too often taught as fact. And we are supposed to kowtow to it: as well as allowing teachers to tell our children about 'gender identity' as though it made sense, we are supposed to alter our society in myriad ways in accord with such nonsense, much as past ages did to account for changing ideas about real presence and suchlike cobblers.
Enough is enough. Sorry, Spooky. For all your good faith, your metaphysics is just wholly incoherent; the societal changes you encourage, the damage already done to children on the basis of something similar, wholly unjustified. Please stop. Think.
[Denying your "something immeasurable ... separate to our bodies", btw, does not entail accepting "we are our bodies". That's just another mistake. Oh well.]
