Well I used to integrate everything that sounded good in my mind into my grand structure; I was one of those kids that would be spelled by the sounds of words in sentences, e.g. watching "Into The Wild" and thinking that it was all good substance, that it all made sense. I've written many of notebooks of thoughts, just spontaneously writing for no reason. It was bullshit. I realized that just because something sounds legitimate does not imply it's correct. In fact, the sound of something should impose absolutely no weight on the logical merit of the statement. I also realized that these ideas I was spitting out were very much inconsistent with the patterns and trends that I've deduced from nature (that's how I validate things somethings), and thus it would justify my scepticism of an idea's logical merit. Every book I wrote was flawed; after going through them years later and identifying the flaws, I was left with little more than I had begun with, but it was the most coherent and sensible thing I had ever produced.
My truth is, that every INTP is doomed to produce huge amounts of random thoughts, about everything. This is like evolution creating a huge amount of random different designs based on spontaneous, instantaneous environmental factors; Of course, a few small percentage (much less than 1%) of those designs are in correspondence with nature, and the rest die off. This is analogous (not identical) to filtering legitimate thoughts--It is your responsibility to impose a selection on your ideas, as you
are prone to come up with all sorts of ideas that seem to make sense, e.g. in a microsystem, although may not be consistent with the overall structure. If the incorrect ideas get into your concept map, and new ideas build
dependencies on those ideas that may be incorrect, well--then your in big trouble. I could not imagine going back and revolutionizing foundational concepts, it's much easier to perform maintenance on the "outer-ring" concepts in the grand concept map, i.e. the ones that other ideas are not dependent on.
Your going to produce lot's of bullshit ideas in your life, there is no one on earth that has perfect thoughts every second. With INTPs, sometimes we can think an entire train of thought without analyzing it's logical merit. When I'm unsure about somethings logical merit, I look at the patterns that I swear by and stay "close to the border" of my grand concept map, i.e. my thoughts are not too farfetched or far-gone with respect to everything else I believe I know for sure. This also allows me to identify contradictions, inconsistencies, lies, etc, coming from other entities, in a second.
I am a scientist; I believe things "happen to be" in nature. I.e. I am an animal and I over-think, no polarity here; the ability to think is an object of being an animal, they are not on the same level of logical hierarchy. I've always been an animal, or rather,
"a union of segregated regions with differing proportionalities of nanomachines that collectively operate a vehicle, fuelled by the cannibalization of other sorts of these unions." This is how I think of an animal--I don't think of it as just
one thing, I must understand this thing on the most fundamental levels such that it is consistent with everything else, i.e. only using common factors can things be effectively compared such that legitimate logical concepts may be deduced. The first paragraph of my post here talks about this animal thing:

And my understanding of emotions are clear--they are merely manifestations of differing proportionalities of chemicals (structures, i.e. 3D shapes..) in the brain based on stimuli picked up by senses and interpreted by the brain (a computer), etc. I believe any other interpretation may put them on a pedestal, i.e. put them too high on the order of logical hierarchy on concepts that describe the universe, which may lead to incoherent models.
And I am plagued in angst; but I feel like I am on the downhill now. For years I held an angst that was a product of my thoughts and ideas, but I feel like they are crystallizing now; it's beautiful. It's my meaning of life. When every idea is crystallized, when everything is entirely predictable and ordered, entropy will cease to exist, and time will become meaningless. I think my point of life is to stop time in this manner; mind you, it is a futile thing--our brain may not possess the processing power to do so, and even if a supercomputer figured it all out, well, then it probably means that we are in a simulation that is moderated by a similar supercomputer, which means we are in a permanent prison; a program, not a reality.
All that's left is to figure out airfare and start building houses.
