Emptiness and tomfoolery
If others were to look attentively into themselves as I do, they would find themselves, as I do, full of emptiness and tomfoolery. I cannot rid myself of them without getting rid of myself. We are all steeped in them, each as much as the other; but those who realize this get off, as I know, a little more cheaply.
Michel de Montaigne [Essays III, 9. On vanity]
