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:
“Nothing in the world can take the place of Persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and Determination alone are omnipotent. The slogan “Press On”, has solved and will always solve the problems of the human race.”
—Calvin Coolidge (1872–1933)
“As siblings we were inextricably bound, even though our connections were loose and frayed.... And each time we met, we discovered to our surprise and dismay how quickly the intensity of childhood feelings reappeared.... No matter how old we got or how often we tried to show another face, reality was filtered through yesterday’s memories.”
—Jane Mersky Leder (20th century)
