I can't, but then I don't speak for everyone else, just for me.
You can speak of say, the legality in another person's action, can't you?
Morality is merely a dictate of moral law.
Who am I to pass judgment on other people? If there is no absolute definition of "Christian" then how could I possibly pontificate on who is and is not?
Of course there is - one who adheres to the teachings attributed to jesus the christ.
Yeah, so what? If you cannot define it in its ENTIRETY then you cannot make any valid statements about the vast majority of it that you CANNOT DEFINE. It's like the blind men examining the elephant.
Ah, but not all avenues of inquiry in science and math are defined in their entirety.
But that doesn't stop us from using them, does it?
Metaphysics is as amorphous and vaporous as religion, you cannot make any demonstrably valid point with either of them. You cannot show that there are "other ORDERS OF EXISTENCE".
Metaphysics is the study of the nature of existence.
One of the most important standards of existence is immutability.
Metaphysics is anything but 'amorphous and vaporous'.
Before you can make the bolded statement truthfully, you will have to prove that "inanimate" objects even exist vis a vis "animate" objects.
In metaphysics, matter has a fluid existence - hence not existence in its truest sense.
A human being, on the other hand, while having a material 'existence', also has will.
A person is always viewed within this duality.
Everything in the Universe appears to be made up of energy, so defining inanimate energy from animate energy is probably impossible.
The universe is made up of mostly 'dark energy' - which isn't like the energy we know of. Its got one foot firmly set in pure speculation.
The good thing about philosophy is that it isn't bound exclusively to empirical phenomenon. It operates on logic alone.
And when one speaks of 'animate and inanimate' in the metaphysical sense, it only means the existence of will.
The "distinctness" to which you refer is a mental construct useful for delineating differences in systems like mathematics, but it doesn't exist demonstrably in the physical Universe.
How can mathematics be a mental construct when it is absolutely independent of subjectivity, eh?
The physical universe, to some extent, may be described both quantitavely and qualitatively. What is that if not a statement of distnctness?
