This is the title of the painting (as seen above) by Francisco Goya made around 1799.
It’s thought provoking. What happens when we give up our critical faculties?
The official motivation for the painting is as follows:
“Goya imagines himself asleep amidst his drawing tools, his reason dulled by slumber and bedeviled by creatures that prowl in the dark. The work includes owls that may be symbols of folly and bats symbolizing ignorance. The artist’s nightmare reflected his view of Spanish society, which he portrayed in the Caprichos as demented, corrupt, and ripe for ridicule.”
