PHILOSOPHY FOR THE 21st CENTURY: TIME

Thinking about the past is really like science -fiction. Let's say you think of someone who lived in 1415. That person woke up one day and thinking about what he wanted to do with his life said to himself...«Let's do it tomorrow I still have a lot of time in front of me.» And then you think that person is now dead since...600  years! That's really the best science-fiction.
