It's not the futility of a discussion that amazes me, it's the indifference towards a consequence that does it. I often wonder, where does the mind seed its most natural thoughts from? I fail to answer this question for myself as much as I want to. It's just a very pointless attempt to do so. This is the same as the question "Can behavior be explained?" If yes, "Is there one explanation?" and so on..
Thoughts are just procreated progressively. Of course. Where do you think debates arise from? Where do you think opinions arise from? Thoughts and opinions are off-springs of seemingly simple and harmless exchanges of energies and yet they grow up into ideologies, longings and comforting patterns.
