Man is so great that his greatness appears even in knowing himself to be miserable. A tree has no sense of its misery. It is true that to know we are miserable is to be miserable, but to know we are miserable is also to be great. Thus all the miseries of man prove his grandeur, they are the miseries of a dignified personage, the miseries of a dethroned monarch…What can this incessant craving, and this impotence of attainment mean, unless there was once a happiness belonging to man, of which only the faintest traces remain, in that void which he attempts to fill with everything within his reach?
– Blaise Pascal – Pensees (17th century)
