Abstract
The idea that we should simply live in the moment, and should not concern ourselves about the future or the past, has long been a staple of popular philosophy. In this paper, I first attempt to clarify the doctrine and then examine the case for accepting it. My conclusions are, first, that a number of its implications seem quite unpalatable; second, that the main advantages that living in the moment are said to yield are greatly overstated; and, third, that to live by any version of the doctrine that was not highly watered down would be to sacrifice much of what gives meaning to our lives.
