I took the one less traveled by,
And that has made all the difference.(
Robert Frost)
When you come to a fork in the road, take it! (
Yogi Berra)
Both quotations have to do with forks in the road. Frost implies he exercised free will and Berra makes nonsense out of the very idea of free choice. The Yankees catcher was good at silly quotes that the press liked to scoop up like fly balls but this one resonates into philosophy and brain science.
We can't start over to discover if we could have done differently because we are creatures of time and perhaps it is merely a construction of our consciousness. Time is what keeps everything from happening all at once, as John Wheeler put it, which is another way of saying we are dimensionally constituted to handle one thing at a time.
