The quote below is from Franco Berardi’s book The Soul at Work: From Alienation to Autonomy (Semiotext(e)2009)

“The soul is the clinamen^* of the body. It is how it falls, and what makes it fall in with other bodies. The soul is its gravity. This tendency for certain bodies to fall in with other is what constitutes a world.

The soul does not lie beneath the skin. It is the angle of this swerve and what then holds these bodies together. It spaces bodies, rather than hiding within them; it is among them, their consistency, the affinity they have for one another. It is what they share in common: neither form, nor some thing, but a rhythm, a certain way of vibrating, a resonance. Frequency, tuning or tone.”  

^*Clinamen is the Latin name Lucretius gave to the unpredictable swerve of atoms, in the atomistic doctrine of Epicurus.
