Akinbo My Friend,
I want you to understand me rightly, and out of respect I am posting it here. While I acknowledge that sometimes life reduces chices down to either/or decisions, the tendency to assume this applies more generally is a harmful logical flaw prevalent in modern society, because it fails to ask "Is there a middle path?" In more detail; sometimes the middle is excluded erroneously, in other cases the fact there are multiple choices is not considered, and in some cases there is a virtually continuous range of choices - where sometimes our choice among these cases is determined by how we interact with the system. According to an article in August's Scientific American by Meinard Kuhlmann; that sometimes applies for the choice of 'particles vs vacuum' which begs the question "Is there a particle or no particle?"
I first read about the hierarchy of objects and spaces as a point made in passing by Alain Connes, in one of his papers about non-commutative geometry. Measurable is a subset of topological, which is a subset of smooth - in relating the categories of well-defined spaces. This point has more than passing importance, however, to people who study differential geometry and topology. In some cases; one can assert that the boundary between stable conditions or well-defined regions is a fractal. That is; there are interpenetrating regions of yes and no, or black and white, as in an M.C. Escher artwork. So while sometimes a simple yes or no will suffice; sometimes a more subtle answer is called for.
The studies begun at Tübingen, and run by the German Psychological Association for a number of years, showed a marked decline in the perceptual acuity in discerning shades of gray and other colors, for people at the end of the study vs the beginning. Early on more than 200 shades were easily distinguished, and later participants could discern half that - focusing mostly on bright colors. I would hate to imagine a world where everything had to be reduced to yes or no, black or white.
All the Best,
Jonathan
