It seems to be implied in Objectivism that there is going to be this giant catastrophe like in Ayn Rand's novel Atlas Shrugged that is going to force human society to go from Subjectivism to Objectivism. I can personally remember during the Great Recession, whose worst years were approximately from 2008-10, at least some Objectivists saying "this is it! this is Atlas shrugging!" But that didn't happen. Here we are in 2016, the world got back on its feet and "Subjectivism" has kept on rolling.
Catholic dogma WAS Aristotelianism/Thomism.
It wasn't until this Scholastic, deductive-logic approach to science was "thrown-off" [largely by the British Protestants/Puritans associated with the Royal Society, and the School known as Empiricism (Bacon, Hooke, Boyle, Newton, Locke, Berkeley, Hume, etc.)] that major strides in science were even possible.
There is a difference between "Aristotelian Logic" and being "logical".
