Persistence Over Time
Common-sense tells us that objects persist across time, that there is some sense in which you are the same person you were yesterday, in which the oak is the same as the acorn, in which you perhaps even can step into the same river twice. Philosophers have developed two rival theories for how this happens, called endurantism and perdurantism. Broadly speaking, endurantists hold that a whole object exists at each moment of its history, and the same object exists at each moment, while perdurantists believe that objects are 4-dimensional entities made up of a series of temporal parts like the frames of a movie.

Famous quotes containing the words persistence and/or time:
“Extreme patience and persistence are required,
Yet everybody succeeds at this before being handed
The surprise box lunch of the rest of his life.”
—John Ashbery (b. 1927)
“The vines of her arms
didn’t cling to the ends of his clothes,
or did she plant herself in the doorway,
hurl herself at his feet,
or utter the word “Stay!”
But as that fool began to go
at the time when it was dark with swarming clouds,
the slim girl blocked her lover’s way
with only a rising river
made with her flood of tears.”
—Amaru (c. seventh century A.D.)
