" And amid all this confusion I, what’s truly I, am the centre that exists only in the geometry of the abyss: I’m the nothing around which everything spins, existing only so that it can spin, being a centre only because every circle has one. I, what’s truly I, am a well without walls but with the walls’ viscosity, the centre of everything with nothing around it. — Fernando Pessoa, The Book of Disquiet. (Penguin Classics; New Ed edition, December 31, 2002) Originally published 1982. "
