It is perhaps a moot point as to exactly who is the rider of unicorns. But here is the crux, if we think that others are the metaphorical unicorn riders, we are at least giving credence to the notion of unicorns, if only metaphorically.
So in a derby which unicorn would win? If you went down to the bookies and looked in “The Racing Post” on what basis would you place your bets, hypothetically speaking?
I suspect, what with unicorns being intangible and all that, many may be unaware that they are riding unicorns. They fail to see the point, even though it might be right in front of them.
When it comes down to it, we all have to place our bets on what we believe, what we want to believe and most of all what is convenient for us to believe.
