Euphemisms about the future often describe our relationship to it in active terms. We are “creating the future” or we are “making the future happen.”
But when you really think about it, we are sort of doing the opposite. Simply by existing, every day of our lives we convert another day of the future into a day of the past.
In that sense, there is less and less future all the time. What had once been the future is continually vanishing right before our eyes, only to become the past.
I guess in metaphysical terms this all makes sense. The future is our temporal sustenance, the very food of our continued existence.
In order to live, we eat the future. We just have to hope that our food doesn’t end up running out too soon.
