I believe the defining characteristic of existence is novelty. This may explain why existence occurs over nothing at all. This may explain why we appear to be able to make a choice, and at the same time live in a system where choice is seemingly impossible. A way to view choice logically is to consider it real insofar as it creates novelty. If it doesn't it's just an illusion. This may explain why some decisions, no matter how inconsequential, feel more important than others. It explains why chaos has order.
The reason why academic philosophy may have ground to a halt is because of the occult. The very nature of a global society which large conceptual gaps. Secret societies have, thus far in this history, served as a conduit to pass on certain truths. The world is run by these secret societies in the sense that they use certain scientific laws that exist outside of the public's conceptual base, and hence public science. One of the things that the public is shielded from is the fact that the laws of physics actually change depending on who, and how many people, are involved. This is why many self-professed psychics have demonstrably failed in front of an audience of skeptics, and why weird shit goes on around religious people. A group of 10 children holding hands can, and have, instantly killed entire villages of people. I have personally partaken in timed meditations aimed at one specific person (usually in distress) and seen the effects that a couple minutes of intention can achieve when multiplied by enough people. Imagine what a global consciousness still caught in the throes of self-actualizing as sentient beings would result in. When you imagine that type of a global consideration you perhaps start to realize why these truths are kept hidden in the first place. This is the function of Masons, Templars, and all the rest of those funny handshake henries.
If you look hard enough you will find evidence for the existence of a past civilization(s). The macro evolution theory is an elaborate lie, essentially, designed to limit conceptual areas of thought in the manner that keep people from realizing the true power the hold. If you tell people they come from apes they will act like apes, and we do. Regardless of whether or not you accept that, this is not the first time that we've done this. The question is whether the preexisting 'Atlantean' society annihilated itself from existence finally, or in the sense that collectively they existed this, what is for the most part a linear, mechanistic dimensional framework, and moved onto something else---ironically enough this seems to be the subconscious direction of any good, well-intentioned person: the desire for a sort of relatively Utopian experience. The existence of the psychopaths who, in their desire for power over a chaotic universe, unknowingly facilitated our collective arrival to this point in time is explained by novelty.
In accordance with novelty all things which are hidden eventually become unhidden. Terrence McKenna, aided by a sort of channeled insight induced by magic mushrooms while living in South America was able to decode the fractal nature of the I-Ching---one of, if not humanities oldest puzzle. The consequence of this decryption was an algorithm he called the Timewave, a literal wave function, which, when mapped onto human history, spikes at moments of retrospective moments of novelty: renaissance, splitting the atom, internet, etc. This matches up perfectly with the Mayan conceptualization of time and the workings of the universe, which of course points to some sort of a threshold event around the end of 2012. There has been endless speculation regarding 2012 but I think the novelty explanation is the best, currently. McKenna says that the time leading up to 2012 will get exponentially more novel, compounding all the the novelty of all human history into the last second before the wave function goes flat. If, globally, we realize that the laws of physics literally obey our commands that would be pretty novel now wouldn’t it?
