Abstract

Eclipses are proverbially fraught with forebodings. The solar eclipse of 1919 was no exception. Seen in retrospect, that eclipse marked the end of an old era and the beginning of a new in the philosophy of science. Not in science itself, be it noted, for the scientific life is a life of patience and sobriety and continuity, knowing little of what the world calls ‘sensation’. But for the onlookers, the philosophers of science, the event was drama. The reign of Newton, long tottering, was finally broken; Einstein took up the vacant chair. Men were not slow to learn the lesson: if king-making can be done once it can be done again. Philosophy of science must needs hereafter be a philosophy of revolutions—whether continuous revolution or spasmodic revolutions is still a subject of debate.
