All revolutions have the (un)fortunate side effect of altering much more than what they’ve initially set out to change. Whether we’re talking about a political act or a scientific breakthrough, a revolution begins with a magical act. What was previously seen as impossible, in a moment, is overcome. Spontaneous outbursts of mass movements (often accompanied by violence) cause major political upheavals, innovations in science and medicine cause humans to live longer or reach other planets, while artistic revolutions cause us to perceive and see in radically different ways. Revolutionary moments happen quickly. But their aftereffects can be felt for many years.
