Daemonican entity 127/8888: ξ = Xi, in intentione recta. Ludwig Wittgenstein used ξ as a variable in Tractatus Logico-Philosophicus to represent aspects of his “propositions”. He was a mystic who hid his incantations in his philosophy, like how 6.522 + 2.003 = 7. A Daemonican entity is also a proposition, qualitas occulta.
