Back to Nabokov's Spiral

I feel like I'm behind on posts, but I still want to share my thoughts.

We had a discussion in class about the spiral, and though my book is a bit different in pages, I want to bring up the first two sentences of Chapter 14 in "Speak, Memory"

The spiral is a spiritualized circle. In the spiral form, the circle, uncoiled, unwound, has ceased to be vicious; it has been set free.

I would like to point out that "spiritualized" is not even an official word, probably along the same lines as the term "chronophobe." With that aside, I would like to point out that in a spiritual or religious sense, circles are used as symbols of eternity. Here, Nabokov sees circles as vicious and only until it's uncoiled is it free. I always saw circles as peaceful things myself, so I tried to think of it the way Nabokov seems too. A circle is made of a line that is perfectly curved that finishes where it starts so it is continuous and you can not find the beginning or end. Then I thought, that even though a circle is eternal, it is also so finite. You can't travel beyond that line of that circle, and it just keeps looping you through the same path, just over and over and over again. A spiral, though still looping, moves you progressively forward, or back for those that see the glass half empty. Either way, there is something more than that same area, and you just keep going and going like the Energizer Bunny.

I guess circles are vicious... I know there are some events I'd rather not repeat exactly the same.
