Gould's arguments on the quirkiness of human intelligence are not only presented as part of an evolutionary argument, but also I believe to buttress an ideological viewpoint. In brief, his assessment of Man as an evolutionary accident is to lead us into a libertarian attitude whereby, by virtue of a cosmic accident, we, and we alone, have no choice but to take responsibility for our own destiny and mould it to our desire.
An architect should live as little in cities as a painter. Send him to our hills, and let him study there what nature understands by a buttress, and what by a dome. There was something in the old power of architecture, which it had from the recluse more than from the citizen.
