The present is only a continuation of the past.

We are all tomorrow's past.

The past cannot be altered except by historians.

Yesterday was our past; today is our future for tomorrow is unknown.

The present is judged by the past.

To live for the moment is not to deny the past.

Those who don't remember the past are condemned to repeat it.

All times past were good.

Obsession with the past can ruin our future.
