“In the world of eternal return the weight of unbearable responsibility lies heavy on every move we make. That is why Nietzsche called the idea of eternal return the heaviest of burdens.
If eternal return is the heaviest of burdens, then our lives can stand out against it in all their splendid lightness.
But is heaviness truly deplorable and lightness splendid?
The heaviest of burdens crushes us, we sink beneath it, it pins us to the ground. But in the love poetry of every age, the woman longs to be weighed down by the man's body. The heaviest of burdens is therefore simultaneously an image of life's most intense fulfillment. The heavier the burden, the more real and truthful they become.
Conversely, the absolute absence of a burden causes man to be lighter than air, to soar into the heights, take leave of the earth and his earthly being, and become only half real, his movements as free as they are insignificant.
What then shall we choose? Weight or lightness?
...That is the question. The only certainty is: the lightness/weight opposition is the most mysterious, most ambiguous of all.”
