Old age, especially an honored old age, has so great authority, that this is of more value than all the pleasures of youth.
Marcus Tullius CiceroArmed forces abroad are of little value unless there is prudent counsel at home
Marcus Tullius CiceroWhen I consider the wonderful activity of the mind, so great a memory of what is past, and such a capacity of penetrating into the future: when I behold such a number of arts and sciences, and such a multitude of discoveries hence arising,--I believe and am firmly persuaded that a nature which contains so many things within itself cannot be mortal.
Marcus Tullius Cicero
