Setting Sail

And so the coin was thrown in the air, turning many times, landing sometimes heads and other times tails. Man, the measure of all things, speaks here through my mouth and narrates in my own language that which my eyes have seen. It is likely that out of the 10 possible heads, I have only seen one true tail, or vice versa. In fact, it's probable, and there are no excuses, for these lips can only describe what these eyes actually see. Is it that our whole vision was never quite complete, that it was too transient or not always well-informed? Were we too uncompromising in our judgements?
