And it is hard to imagine any human act or endeavour that does not depend on the ability to conceive the existence of time beyond the immediate moment. We could not have intentions or decide to go out of the house, or build dwellings or voyage across the sea and savannah, without some projection into the future. We could not recognise ourselves each morning as the person we were yesterday without the mind’s constant reach into the past through memory. We could not even register the awareness of a fleeting moment without the perception of time’s fleet progress.
