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)
“In a time of war the nation is always of one mind, eager to hear something good of themselves and ill of the enemy. At this time the task of news-writers is easy, they have nothing to do but to tell that a battle is expected, and afterwards that a battle has been fought, in which we and our friends, whether conquering or conquered, did all, and our enemies did nothing.”
—Samuel Johnson (1709–1784)
