I think I respectfully disagree almost entirely. Maths requires a huge amount of creative effort and there often is no logical next step. There was a reason that it took three hundred years to go from an idea that a^x + b^x = c^x has no integer solutions when x is greater than two, to a proof of that, and it involved some crazy twists and turns of thinking. However, while a pyramid may have a definite endpoint, cathedrals have historically been in a near constant state of flux - a bishop wants to show his influence and rebuilds a tower higher, a burgher of the town want to show his power by adding a side chapel. New windows are installed, a porch is demolished and replaced with something more beautiful. For the cathedrals which took five hundred years to complete, it wasn't that they were abandoned building sites during that time - they just took that long to reach the state that we see as final today. Maybe in-between there was a wooden roof instead of a stone roof, or a tower was capped at thirty meters tall rather than fifty!
