Single Idea 9666

[filed under theme 27. Natural Reality / D. Time / 1. Nature of Time / g. Growing block ]

Full Idea

It is hard to believe that any philosopher means it when they say the future is unreal. If anyone is right that there is no future, that moment is their last, and it is the end of everything.

Gist of Idea

It is quite implausible that the future is unreal, as that would terminate everything

A Reaction

A bit simplistic. I might say 'there will be a future time, but it doesn't exist now'. That's the peculiar thing about time. If I say New York doesn't exist, then clearly I can't visit it. The London 2012 Olympic Stadium is going to exist.
