What this quote means

Calvino suggests that progress and modernity, symbolized by lighting, do not chase away ancestral fears; on the contrary, they make them more visible, like ghosts seeping through walls. The more we try to illuminate our world, the more we become aware of what remains dark within us and in our society. This image evokes the illusion of modern comfort that does not resolve deep anxieties.

How to apply it daily

Examine a fear you thought you had overcome through material comfort. Explore its inner source and address it directly, rather than masking it with distractions.
