Nature abhors a vacuum. When a head lacks brains, nature fills it with conceit.
Silence accompanies the most significant expressions of happiness and unhappiness: those in love understand one another best when silent, while the most heated and impassioned speech at a graveside touches only outsiders, but seems cold and inconsequential to the widow and children of the deceased.
Everything dies eventually. We all know that. People, cities, whole civilizations. Nothing lasts. So if existence was just binary, dead or alive, here or not here, what would be the fucking point in anything? My mom used to say that's why we have memory. And the opposite of memory - hope. So things that are gone can still matter. So we can build off our pasts and make futures.
