Is it possible to clarify the "helical change" in Hegelian dialectic with an example?
Hegel proffers weltanschauung to be either agreed or disagreed with. Note that while this is distinct from advancing knowledge claims, it is the logical equivalent of poetry and no more philosophy than opinion or sentiment. So, sure - it's possible to clarify. What then does the poet mean when one interpretation is as valid as the other? From "Dialectics for Kids"
Many changes are cyclical--first one side dominates, then the other--as in day/night, breathing in/breathing out, one opposite then another. Dialectics argues that these cycles do not come back exactly to where they started; they don't make a perfect circle. Instead, change is evolutionary, moving in a spiral.
...these are the ABCs of spirals:
A - An Acorn falls in the woods. It sprouts into a tree that eventually makes new, and different Acorns.
B - You're walking along and you happen to trip. Next time you're more careful to keep your Balance.
C - It's the big game. You're team starts to lose and you're feeling bad. But then you feel great when your team makes a Comeback.
D - A baby doesn't know how to use a bathroom so we use Diapers to keep from having a mess. When a toddler learns to use a bathroom we're glad that there is no more need for the Diapers
...and so on.
Here as well is further example by poetic use of analogy, from Popcorn, Haircuts and other Changes:
Circles and Spirals
Some changes go in circles, returning to where they started.
Like a Ferris wheel that goes up and comes back down to the same spot. Or the day which turns into night and then into day Or the seasons--Winter--Spring--Summer--Fall--and Winter again Or our breathing--in and out and in
Some changes go in spirals--they look like they come back to where they started, but something is different.
Like a winding staircase that moves in a circle, but comes around to a higher point. Or going to school and coming back home, but learning more about the world every day. Or losing something; then finding it, and then putting it in a special place so you won't lose it again. Or like children growing up to be parents with children of their own.
