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 Lord is thy keeper; the Lord is thy shade upon thy right hand.
The sun shall not smite thee by day, nor the moon by night.

soul.
The Lord shall preserve thy going out and thy coming in from this time forth, and even for evermore.”
