The whole poem (Four Quartets), time is divided into three kinds, (1) the time particular to science, in particular, quantum physics and to a similar extent to Einsteinian/relativistic time, (2) common or historical or "real" time and (3) the eternal, spiritual or religious time of Eliot's devout Christian Anglican faith. While these three kinds of time are all evident in "Burnt Norton," "Burnt Norton" is unique-even within the wide and somewhat eccentric parameters of the whole poem-by concentrating most particularly on quantum time.
