💬 secrets, stories, logic and disco

The following quote from Disco Elysium (one of many notable examples) sounded vaguely familiar in its wording:

Secrets are the currency of human relations.

A quick search unearthed this strikingly similar one:

 “Stories are the currency of human relationships.”

— Robert McKee, Story: Substance, Structure, Style, and the Principles of Screenwriting (1997)

And of course, as is fitting for such a game, we have a possible inspiration from Karl Marx with his “Die Logik ist das Geld des Geistes”, or Logic is the money of the mind.”

So which is it then – secrets, stories, logic? Or disco?
