Philosophy - You can never step into the same river twice


Expert: J.M.J. West - 5/3/2009

Question
Hello, how are you? I would like to talk about a particular situation.  I'm sure you have
heard of the phrase " You can never step into the same river twice". To me, this
basically means that a person's experience compared with another experience(s) can
never be exactly the same, even if the general experience is of the same nature. But
what happens if suddenly stepping into the river day after day gets boring and
stressful? Is there something wrong with the river or with the person stepping into it?
Is the person doing something wrong, approaching it in the wrong way, or is there
some psychological component to this? (Let's say the person is doing the best he/she
can, and trying to stay positive.) What does the river stand for metaphorically
anyway? (Sometimes the river seem hard to comprehend and just seem hard to grasp
mentally). Sometimes the river seems random and hard to control. What are your
thoughts on this? Thank you for your time.

Answer
Heraclitus said this famous phrase, and it wasn't in reference to a metaphorical river, but to an actual river.  Early philosophy was concerned with explaining change and what it meant to our very ability to persist through time.  When he said that you cannot step into the same river twice, he meant quite literally that the river you step in is very different each time you step in it (from a purely molecular level, this is true, as water which was upstream is now down stream, and none of the water molecules are where they were when you first stepped into it).

As for the discrepancy of perceptions (ie. "a person's experience compared with another experience(s) can never be exactly the same, even if the general experience is of the same nature"), a number of philosophers have noted this, and it leaves one either accepting an Aristotelian theory of forms in knowledge (i.e. the overarching form of the thing experienced remains the same, so all knowers know the same thing by knowing its form, or else a radical skepticism a la Quine and the other moderns who think you can know nothing.).

Hope that helps!

Pax,

-J.M.J. West
