Marcus Tullius Cicero
To be ignorant of what occurred before you were born is to remain always a child.
Not to know what happened before you were born is always to remain a child. For what is a man's life if it is not linked with the life of future generations by memories of the past.
Quod est ante pedes nemo spectat: coeli scrutantur plagas.(No one sees what is before his feet: we all gaze at the stars.)
For no phase of life, whether public or private, whether in business or in the home, whether one is working on what concerns oneself alone or dealing with another, can be without its moral duty; on the discharge of such duties depends all that is morally right, and on their neglect all that is morally wrong in life.
