We here in the United States are celebrating our Memorial Day this weekend. It's a time when we pause to remember those who were willing to risk everything for a cause that they deeply believed in. We are a nation at war, and we remember not only those who served and died long ago, but also those who served long ago and have recently died as well as those who have recently died in service. Remembering those who have passed away is only one tiny factor in the incredible influence that our memories have: not only its influence over our own selves, but over others, over the planet and — whether or not you're prepared to hear and accept this — over the course and destiny of the universe itself.
It's important to take a few moments, as we remember those who have gone before us, to reflect, first of all, on the role that memory has to play in our lives (particularly at midlife), and then, on the role that memory has to play in determining our singular and collective future. Nearly every living organism from the single-celled upward to the most complex lving creature has the capacity to learn. Experience seems to be endemic to what it means to be a sensate being. In higher organisms, parents use this capacity to learn in order to train their offspring to behave in certain ways: to avoid seductively dangerous situations and to modify their behavior in ways that actually promote their well-being as individuals and as a species.
