This leaves out movements, including both cults, and movements like evangelical and born-again; it also leaves out much that could be said (including lateral transfers, mergers, and dissolutions), but I'm trying to focus on schisms that are close to the trunk.
I don't see why you chose to fixate on the word "great" when I was only referring to a common saying.
A conclusion is something, so I don't understand what you mean? If I use philosophy to conclude that abortion is murder and therefore wrong and hence decide not to abort my child, that is most definitely "something" other than "mental masturbation".
You're right I didn't get the slightest enlightenment out of them but perhaps I misunderstood and they just need to be explained better.
What I would note here is that you keep coming back. Is it to share information because you believe I might find it of relevance and importance? No one could be that dim, but it's what your subconscious tells your conscious to believe is the reason.
You see, you aren't looking for enlightenment, which would entail giving up some of what you already believe. You simply desire confirmation of what you already think. It traces further but is, in fact, the path of the phenomenon of confirmation bias.
You subconscious has already silently judged that what I said had merit and this disconfirming information disturbed your worldview. That produces anxiety and that anxiety must be relieved. Your conscious is tasked to "prove" that the new information is "wrong", thus to restore internal stability.
Seriously, try your best not to respond to this. Just let me be wrong like the billions of other people on the Internet and silently go on your way. With any capacity for self-reflection, you'll observe your conscious furiously thinking up all the things you need to write back but cannot, lest you give practical verification of all I just said. Quite the dilemma.
Until next time!
