Before the Age of Reason was announced, humanity had polished strategies for interacting with the world of the imaginary and invisible: complicated magic-systems; sprawling pantheons of gods and spirits, images and names with which we labelled powerful inner forces so that we might better understand them. Intellect, Emotion and Unconscious Thought were made divinities or demons so that we, like Faust, might better know them; deal with them; become them.
Ancient cultures did not worship idols. Their god-statues represented ideal states which, when meditated constantly upon, one might aspire to. Science proves there never was a mermaid, blue-skinned Krishna or a virgin birth in physical reality. Yet thought is real, and the domain of thought is the one place where gods inarguably ezdst, wielding tremendous power. If Aphrodite were a myth and Love only a concept, then would that negate the crimes and kindnesses and songs done in Love's name? If Christ were only ever fiction, a divine Idea, would this invalidate the social change inspired by that idea, make holy wars less terrible, or human betterment less real, less sacred?
The world of ideas is in certain senses deeper, truer than reality; this solid television less significant than the Idea of television. Ideas, unlike solid structures, do not perish.
