In life there are so many factors involved that mathematical enumeration is the smallest and often the least important element involved. No illustration is more apt than the time-worn example of the logics, wherein it is presumed that if one man could dig a well in ten days, ten men could dig it in one. The mathematics is, of course, perfect, but worthless as overlooking the fact that ten men would, in that kind of a task, be in each other’s way.
