“The Gods we worship write their names on our faces; be sure of that. And a man will worship something ... That which dominates will determine his life and character. Therefore it behooves us to be careful what we worship, for what we are worshipping we are becoming.”
The ancient Hebrews knew this, of course, long before Emerson.
Their idols are silver and gold,
the work of human hands.
They have mouths, but do not speak;
eyes, but do not see.
They have ears, but do not hear;
noses, but do not smell.
They have hands, but do not feel;
feet, but do not walk;
and they do not make a sound in their throat.
Those who make them become like them;
so do all who trust in them. (Psalm 115:4-8)
