Interstellar’s scientific pretensions capture the religious spirit of our times. What should we make of all the talk of the incompatibility of science and religion? Nothing: Longing for future glory is alive and well among the scientifically literate. Some of their own apparently comprise the most fervent devotees of future hope, displaying the same desire for human transcendence as the ancients but clothing it in modern science. Interstellar is worth reflecting on, not for any dubious relation it may bear to our future, but because of its indebtedness to the past: It is an ancient myth retold and centuries of scientific progress have diminished none of its appeal.
