the brut first knows death when it dies, but man draws consciously nearer to it every hour that he lives; and this makes his life at times a questionable good even to him who has not recognised this character of constant anaihilation in the whole of life.
Arthur SchopenhauerEvery new born being indeed comes fresh and blithe into the new existence, and enjoys it as a free gift: but there is, and can be, nothing freely given. It's fresh existence is paid for by the old age and death of a worn out existence which has perished, but which contained the indestructible seed out of which the new existence has arisen: they are one being.
Arthur Schopenhauer
