Steven Weinberg on whiggish history of science:
… scientific history with an eye to present knowledge is needed by scientists. We don’t see our work as merely an expression of the culture of our time and place, like parliamentary democracy or Morris dancing. We see it as the latest stage in a process, extending back over millennia, of explaining the world. We derive perspective and motivation from the story of how we reached our present understanding, imperfect as that understanding remains.
