“When a book and a head collide and there is a hollow sound, is it always the book?”Georg Christoph Lichtenberg · Caietele de însemnări · 1799 · Caietul K, însemnarea 18
When a book sounds hollow on impact, the hollowness may be in your head.
The image is comic: two heads colliding produce a hollow sound — but which one is hollow? Lichtenberg flips the reflex of blaming the object. A book may be dense, while the head meeting it half-prepared hears only emptiness. A modernist novel abandoned at page thirty as boring may simply demand a different kind of attention than the one judging it.
Passage 1 takes the idea a step further: it is not only that the hollow sound may come from our own head — we can actually check. Lichtenberg does not say "believe everything you read"; he suggests a small honesty question: what did I bring to my meeting with the text? Did I read with patience, or with boredom already installed? It is like calling a friend boring after talking to him for three minutes, forgetting that you never asked him anything. The test is not a humiliation but a tool: it separates real judgment from reflex. And if the hollow sound sometimes comes from our own head, a harder question appears: how do we train the head to sound different at the next collision?
Why it matters A good antidote to the reflex of quickly dismissing a difficult work or idea as empty.
