When I try to distinguish between Fi and Ti (which is hard for me) what the bottom line is is that Ti will divide fully into nothingness, and then stay there wait until something emerges/is created. Fi will reach a point where it no longer will divide, out of biotic respect. I use the metaphor of the atomic bomb thinking about this sometimes. Ti has the need to divide regardless of the consequences, it has to see what is at the bottom, even if it completely wipes the slate and creates a bunch of mutants. Fi respects the mystery and generative sanctity of the shrouded individual life-force. To look, by pulling back the shroud, would be to pollute this power. But idk if that makes sense to people, and I can’t place myself as one or the other.

As far as ethics, I personally treat ethics as a construction. If it comes down to it, ethics are built off this individual life-force (so Fi I guess) and are at root the attempt to respect this force as fairly as possible. This gets complicated because the individual life force bleeds into the collective, and it is not easy to know what is most important to prioritize the respect of. That is a matter of perspective. I tend to also lean absurdist, that it doesn’t really matter, only appears to matter from a human perspective, being enmeshed in suffering. If there is an arbitrary ethical structure, the human condition renders any attempts to achieve it imperfect. Which is the point of being human, to grapple with these imperfections. Again no idea if that made sense. These things are hard to precisely articulate.
