The life given us by nature is short, but the memory of a life well spent is eternal.

The life of the dead is placed in the memory of the living. [Lat., Vita enim mortuorum in memoria vivorum est posita.]

Memory is the treasury and guardian of all things. [Lat., Memoria est thesaurus omnium rerum e custos.]

Wise men are instructed by reason; men of less understanding, by experience; the most ignorant, by necessity; the beasts, by nature.

Amicitiae nostrae memoriam spero sempiternam fore

Nature abhors annihilation. [Lat., Ab interitu naturam abhorrere.]
