The words ‘know thyself’ – ‘gnothi seauton’ – were inscribed in stone above the Ancient Greek Temple of Apollo at Delphi. Philosophers have mused on self-knowledge and its uses ever since. But is it possible to ever ‘Know Thyself’? Psychologists, such as Bruce Hood, have even suggested that the self is an illusion and there may not be a self to know.
