Pragmatic Semiotic Information (Ψ)

I remember it was back in ’76 when I began to notice a subtle shift of focus in the computer science journals I was reading, from discussing X to discussing Information About X, or $X \to \mathrm{Info} (X)$ as I came to notate it.  I suppose this small arc of revolution had been building for years but it struck me as crossing a threshold to a more explicit, self-conscious stage about that time.
