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)
“How soon country people forget. When they fall in love with a city it is forever, and it is like forever. As though there never was a time when they didn’t love it. The minute they arrive at the train station or get off the ferry and glimpse the wide streets and the wasteful lamps lighting them, they know they are born for it. There, in a city, they are not so much new as themselves: their stronger, riskier selves.”
—Toni Morrison (b. 1931)
