Are these tensions related to events of the past or rise only out of the events of today?

CRT Discussion
“One of the most common arguments in favor of studying history, the famous quote by George Santayana, which states ‘Those who cannot remember the past are condemned to repeat it’ means that people who do not learn from the mistakes of the past are going to make the same mistakes. The saying is true of both world history and personal history” 
What to do:
Post a 300-word reflection regarding George Santayana’s quote above. Do you agree or disagree? Are there examples you can point to that prove the events of the past can be reflected in the events of today? Or is there an argument to be explored that the past doesn’t matter? That our innate senses of morality or right and wrong should be enough to guide us in our social behaviors or interactions today? What might be the reasons for the racial tensions of today? Are these tensions related to events of the past or rise only out of the events of today? Your post won’t answer all of these questions, or course. In fact, your post may simply help you and your classmates explore this social conversation without your coming to a conclusion.
