Something to reflect on as the clocks change:
"Imagine the Earth devoid of human life, inhabited only by plants and animals. Would it still have a past and a future? Could we still speak of time in any meaningful way? The question 'What time is it?' or 'What's the date today?' -- if anybody were there to ask it -- would be quite meaningless. The oak tree or the eagle would be bemused by such a question. 'What time?' they would ask. 'Well, of course, it's now. The time is now. What else is there?'"
