About to go to Greece again, haven’t been for ages. In ancient times their use of the word ‘gnosis’ was a turning point in Human Intelligence. Gnosis translates to ‘I see’ or ‘I know’, it was used by Heraclitus around 650 BC. I think this was significant for human evolution and the realisation of a perceiver, identity. Humans needed identity to progress this far, the have and have nots.
