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)
“When you get out on one of those lakes in a canoe like this, you do not forget that you are completely at the mercy of the wind, and a fickle power it is. The playful waves may at any time become too rude for you in their sport, and play right over you.”
—Henry David Thoreau (1817–1862)
