Those who do not learn from history are doomed to repeat it. (George Santayana), 19th-20th centuries Spanish philosopher and writer)

It’s a common expression, but it bears repeating, because every generation needs to be reminded of its importance. You might easily wonder if certain writers and leaders recognize that what they are promoting has often been tried before with complete failure. If we can learn from the mistakes of our forebears, we have a better prospect for success.

Teach us to number our days that we may gain a heart of wisdom. (Psalm 90:12).
