Those who cannot remember the past are condemned to repeat it. GEORGE SANTAYANA, Reason in Common Sense

Studying history makes you feel like you understand something. But until you’ve lived through it and personally felt its consequences, you may not understand it enough to change your behavior.

Unlike many “hard” sciences, history cannot lend itself to experimentation. But somehow, overall, history is potent enough to deliver, on time, in the medium to long run, most of the possible scenarios, and to eventually bury the bad guy.

History isn’t the study of the past; it is the study of change. History teaches us what remains the same, what changes, and how things change.
