 Prospective memory refers to the ability to remember to perform a planned action, or to execute an intention. Failures in prospective memory are of considerable everyday significance and often cause some personal concern. Experimental and naturalistic work on prospective memory now flourishes in psychology (McDaniel &amp; Einstein 2007), and there is considerable discussion about how it relates to other forms of memory and to other cognitive processes. Prospective memory has not yet been addressed much in philosophy, but this is likely to change given its relevance to understanding links between intention and action and to other forms of future-oriented thought.
