Hours and days and months and years go by; the past returns no more, and what is to be we cannot know; but whatever the time gives us in which we live, we should therefore be content.
Marcus Tullius CiceroThe most evident difference between man and animals is this: the beast, in as much as it is largely motivated by the senses and with little perception of the past or future, lives only for the present. But man, because he is endowed with reason by which he is able to perceive relationships, sees the causes of things, understands the reciprocal nature of cause and effect, makes analogies, easily surveys the whole course of his life, and makes the necessary preparations for its conduct.
Marcus Tullius CiceroThe harvest of old age is the recollection and abundance of blessing previously secured.
