daimon

The first, the word 'daemon' is borrowed from Greek daimon and is not very common until Christianity takes hold.

The Yamaguchi-gumi daimon is often called hishi-gata because of its shape.

Add to this Socrates's own personal daimon, who, if I am recalling this correctly, would instruct him against taking certain actions but never instructed him to carry any specific actions out. I've always looked at it as one of the earliest examples of reference to conscience in Western writings.

On the contrary, it is more than likely that the "who," which appears so clearly and unmistakably to others, remains hidden from the person himself, like the daimon in Greek religion which accompanies each man throughout his life, always looking over his shoulder from behind and thus visible only to those he encounters.
