The sound of Thunder is a metaphor for "shocking awake." It's an ancient motif, symbol, and proclamation. The bricoleur, the world-maker tower-builder Finnegan takes a tumble to the sound of the hundred-letter thunderclap onomatopoeia:
Which is said to be a concatenations of parts of the word 'thunder' in several languages. He falls to his death in the beginning, his end is the start in the perpetual cycle that is J. Joyce's Finnegans Wake.
Here is another prophetic pericope extracted from the stream of consciousness; like Nietzsche's Zarathustra, like the existential Dasein thrown into the world, like Chance the gardener in Jerzy Kosiński's Being There, the archetypal NeoSapiens begin their journey in a vaster, sublimated, rarified world.
Whether the thunderclap is to be visceral or subtle, human beings are at a constant crossroads of remaining in the NeoNeanderthal herd or making a quantum jump to the NeoSapiential modus vivendi. The crossroads is always at the immediate moment, and as time accelerates, the precarious gamble of waiting increases in danger. Nothing need be visceral, see how the virtual has now become concrete, how dreams can phenomenally manifest. A Shift is happening, moving away from Plato's Cave and the NeoNeanderthal cave, into the bright future sun. It is not the time for hubris and entrenchment, of grasping to remake the past; hear the subtle thunderclap first, and choose.
