Of course, it is easy to convince yourself that everything you need to know and understand will be available on the current landing (Level), especially as the number of available doors (study areas) seems infinite, and, crucially, if one door turns out to be useless, you can always switch to the door opposite (the alternative arm of the Dichotomy?), and try that!
Mankind’s basic, and still universal, Pragmatism ensures the maximum possible is extracted from each level, but cannot go any further in a coherent and comprehensive way, without transcending that current level’s impasses.
However, new "hidden staircases" are becoming apparent with real potential for revealing a breakthrough.
One is the investigation into the inexplicable Quantum Entanglement, while another is certainly possible with Nuclear Decay. Finally, a third possibility could well be in the genetic role in Evolution – particularly involving the so-called Junk DNA. And, there are many more such quandaries that are beginning to reveal possible ways up!
The following papers, mostly from December 2015, are perhaps the most fruitful concerning the required General Holistic Approach.
