A quote from a 1992 interview of Mexican writer Octavio Paz by Sergio Marras, and the epigraph for a novel that is currently sitting on the blocks (translation mine):

If we think of that trio upon which the modern world was founded–liberty, equality, fraternity–we see that liberty tends to turn into tyranny over others; thus, it needs to have limits; and that equality is an impossible ideal that cannot come to be without the use of force, which implies despotism. The bridge between these two is fraternity, which is conspicuous in its absence.

For some of us, that absence is an inescapable void. Happy 15^th, little bro.
