Euclid’s work ought to have been any educationist’s nightmare… it never offers any “motivations ” it has no illuminating “asides ” it does not attempt to make anything “intuitive ” and it avoids “applications” to a fault. It is so “humorless” in its mathematical purism that… …it should have been spurned by students and “progressive” teachers in every generation. But it nevertheless survived intact all the turmoils ravages and illiteracies of the dissolving Roman Empire of the early Dark Ages of the Crusades and of the plagues and famines of the later Middle Ages. ~ Salomon Bochner 1899 – 1982 - Mathematician
